Trichocereus thelegonus / Echinopsis thelegona Friedrich & Rowley

Trichocereus thelegonus, also known as Echinopsis thelegona, is a columnar Trichocereus species from Argentina.

Pic: Noah Reams

Origin:

Argentina, Tucumán, Salta, 5500-1100 meters altitude

Synonyms:

Trichocereus thelegona, Trichocereus thelegonus, Echinopsis thelegonus, Echinopsis thelegona, Cereus thelegona, Cereus thelegonus

Trichocereus thelegonus is a branchy & creeping cactus that only produces a handful of shoots. It can reach a maximal height of approximately 2.2 meters and can get up to 10 centimeters in diameter. But that´s only the case on very old plants and most of them get 6 – 8 cm in diameter. The plant has 12-13 ribs and is characterized by its very dominant areoles that sit in top of some extremely hexagonal warts. It´s look is very typical and once you got used to the plant, it´s very hard to overlook or misidentify it.

Trichocerus thelegonus has rounded areoles and yellow to dark/brown spines. There also are regional types that rather have a reddish spine color instead of the brown one. Old growth tends to change its color to a more blackish tone, similar to how it can be observed on Trichocereus cuzcoensis. That said, both are really not very similar and this interesting plant from Argentina rather resembles a hanging basket cactus, than a classic columnar. Tr. thelegonus / Echinopsis thelegona usually has one and, in some very rare cases, two middle spines and between 5-8 radial spines that can reach up to 2,5 centimeters in length.

FLOWER:

Trichocereus thelegonus is a night flowering species, with flowers than can stay open until the early morning. The flower is white and gets up to 22 centimeters long and I measured a staggering 17 centimeters in diameter.
Apart from the size, the flower is very beautiful and has a wonderful scent!

Fruits:

The fruits of Trichocereus thelegonus are round and have reddish brown hairs. The fruits are reddish and can reach 6 centimeters in diameter. It does not produce as many seeds as other plants from the same genus. Trichocereus thelegonus / Echinopsis thelegona is self-sterile and it needs pollen from other plants to produce seed.

Trichocereus thelegonus cristata / crest:

There also is a crested clone of this plant that is extremely cool and resembles a monstrose Cereus. I´ve been lookingf or this crest for years, but wasn´t able to find one yet. Luckily, there are some pics from a Botanical garden:

Buy seeds or cuttings of Trichocereus thelegonus / For sale:

This species is kinda rare, but I sometimes get viable seeds of Trichocereus thelegonus. The problem isn´t that there aren´t any seeds available; but most of the ones that were, did not germinate. I am working on putting the type in my shop and if you want to be up to date about my fresh seeds, please subscribe to my newsletter at: trichocereus.net/newsletter.

After all these years, our Trichocereus Facebook group has almost 17.000 members and we´re getting bigger every year. In regards to the subjects and topics that are allowed, we are rather open to off-topic subjects or threads about other cactus genera such as Lophophora, Lobivia, Hildewintera, Pseudolobivia, Ariocarpus, Akersia and many others.There are lots of different threads with hundreds of Trichocereus photos per week.

You can find the group here: facebook.com/groups/trichocereus

The current Christmas seed giveaway in our Facebook group

To celebrate the Trichocereus Christmas spirit, we have organized an amazing seed giveaway this year. Below you can see a small selection of the seed prizes from our 2018 Trichocereus Facebook giveaway. There are many, many more Trichocereus seeds that you can get for free.

These seeds were donated by the family of Karel Knize, the Peruvian seed and plant collector who had just passed away, and we are very proud that we can pass them along to the community.

Secret Santa 2018 Trichocereus Giveaway

In addition to the Trichocereus seed giveaway, we´ll also have a Secret Santa event where our members are gifiting each other with some cactus related gifts. So far we have over 40 participants who are participating, and we still leave it open for new members to join. We´ll probably pick the matching Santas in 10-14 days, and it´s definitely not too late to join.

Regular giveaways, events and Trichocereus and Echinopsis seed trades/sales

We are very welcoming when it´s about events or giveaway, and there´s lots of private members who run their own giveaway or events as well.

Australian Trichocereus clones and hybrids

We´re truly an international Trichocereus Facebook group, and a large part of our members are actually from Australia. Because of this, we see quite a fair share of Trichocereus Australia clones that are being posted in our group.

Members from all across the world

Due to the fact that there are so many different people in our Trichocereus & Echinopsis Facebook group, there are members from all over the world. We have members from Europe, the United States, Australia, India, Africa and and and. Having so many different people in our group provides our members with great insight into the lives of cactus growers worldwide.

Information about the best Fertilizer or Soil Recipes

A large part of the posts in our group discuss the best fertilizer for Trichocereus and Echinopsis, or look into the most unseful soil recipes and minerals that are best suited for Trichocereus. There´s lots of content available about Pumice, Lava, Coir and all the other additives needed by cactus growers.

Trichocereus Tissue Culture, Cytokinines and Plant Hormones

Due to the fact that some of our members are into Tissue culture and have extensive experience with it, there´s quite a few postings about it and how to do it right. Also, there´s many posts about other plant hormones that can be useful, e.g. BAP, GA-3 Gibberellic Acid, etc. All of these can be very useful if you know how to use them.

Trichocereus Pests and Disease Treatments

If your Trichocereus plants are sick, you can find answers about the pests and diseases that affect them in our group. We have threads about pretty much everything that can infect or attack a Tricho, for example Thrips, Root mealies, Fungus gnats, Nematodes, Bugs, Slugs, Snails, Virus infections like Tobacco Mosaic Virus and other viruses, Witches broom disease, etc

DNA Testing on the genus Trichocereus

During the last year, some of our members started organizing DNA testing on plants from the genus Trichocereus and we´ll try to bring in some of the results that we´ll hopefully have during the next years into my upcoming book THE GENUS TRICHOCEREUS. We´ll try to conduct tests on some of the rare species like Trichocereus orurensis, Trichocereus uyupampensis, Trichocereus riomizquensis, etc, to find out if they deserve to be seen as correct and sepparate names or not.

Insight into the production process of the books we make

I am posting regular updates about the book production process in our Facebook group, and pretty much all of the content and photos are shown there as well. If you enjoy the Trichocereus and Echinopsis books that we make, feel free to join our group to see how we´re making them.

Lots of colored flower hybrids and beautiful clones

We have lots of professional breeders in our midst, which is why there´s regular photos of beautiful Trichocereus, Echinopsis or Lobivia flowers to be seen in our group. There´s lots of unique and amazing hybrids like Flying Saucer, Orange California, Wörlitz, First Light, some of the MEX hybrids, hybrids like SUNNY and other hybrids like HELLFIRE, GOLDFISCH, ETC, lots of rare Pseudolobivia and Lobivia hybrids from Thailand and Asia such as BIT, BIV and all the other cool hybrid.s

So yeah, I hope I could give you a small preview of our group and how amazing it is. 😉 Hope to see you soon in our Facebook group.

Trichocereus werdermannianus / Echinopsis werdermanniana

Trichocereus werdermannianus / Echinopsis werdermanniana

Trichocereus werdermannianus, also known as Echinopsis werdermanniana, is a columnar Trichocereus species from Bolivia. It is a close relative of Trichocereus terscheckii and I consider it an intermediate species between the large Andean Trichoereus terscheckii and Trichocereus taquimbalensis.

Original name:

Trichocereus werdermannianus Backeberg & Knuth, Kaktus ABC

Trichocereus werdermannianus is an old name that is debatable because it is so genetically close to Trichocereus terscheckii and might as well be seen as a regional form of it. The plant was discovered and described by Curt Backeberg, who named it after the German Botanist Erich Werdermann.

Trichocereus werdermannianus is a species that is difficult to identify, and its similarity to Trichocereus terscheckii make it difficult to distinguish it from it.

Apart from T.werdermannianus being mislabeled as T. terscheckii, they are also often labeled as Trichocereus taquimbalensis or tacaquirensis. For example, there are a few seed & plant distributors that sell cacti labeled Trichocereus werdermannianus, and the plants we grew from them ended up being all kinds of species. Trichocereus werdermannianus was sold as Trichocereus terscheckii, Trichocereus taquimbalensis, Trichocereus pasacana, Trichocereus peruvianus and Trichocereus macrogonus.

A very constant trait in all Trichocereus werdermannianus plants is the dark green to blue gray green color of epidermis, that is very typical for this species. Most if not all specimens I ever saw had a very dark green epidermis and a spination that looks like a mix of Trichocereus taquimbalensis and Trichocereus terscheckii.

I included the Description from Backeberg´s Book below. Backeberg acknowledges Trichocereus werdermannianus´genetic proximity to Trichocereus terscheckii and Trichocereus validus, but mentions that its flowers usually emerge from the top of the plant, while the two species mentioned before would have flowers that appear at lower regions of the plants body. Based on these observations, we think that it should merely count as a form or variety of Trichocereus terscheckii. That is if we even go so far to split a species up based on such criteria.

Flowers of Trichocereus werdermannianus:

White, flowering from the apex, flowers similar to the flowers of E.terscheckii.

The trees reach a size of 5 meters and a maximum diameter of 65 centimeters. Young plants have 10+ ribs while adult specimens can have 14+ ribs. The plant has ten spines that are between 5 and 10 centimeters long, color between yellow and yellowish brown. Many flowers that arise around the apex of the plant. The flowers can get up to 22 centimeters long, but the whole complex is very variable in this regard. The fruit is up to 4 centimeters in diameter and has many white or black hairs.

Trichoecreus werdermannianus seeds

The seeds of this species are usually 1,4 mm large, but that is also influenced by other factors such as region, plants that grow in direct neighborhood.

Origin of E.werdermanniana:

Bolivia, the type location is in the Charcoma Valley east of Tupiza. However, the species is also present around Potosi. Backeberg suspected that Trichocereus taquimbalensis from the region around those aforementioned locations is actually Trichocereus werdermannianus. It is obviously related to Trichocereus taquimbalensis, but there are substantial differences between these two species.

The first Two Pictures are in Fact the plant that Backeberg understood as Trichocereus werdermannianus. Pictures from the unspeakable Thunderhorse! 😉 In Front on the lower left: True validus! Please note that some pics on this page actually show plants labeled Trichocereus werdermannianus, but get very close to Trichocereus taquimbalensis.  It´s probably not that easy to draw a firm line between these two species sometimes.

The three pics above show seedlings that were raised from KK1094 Trichocereus werdermannianus seed. Please note that those seedlings actually ended up being Trichocereus taquimbalensis var. wilkae instead
Knize used this number for two plants. First, Trichocereus giganteus and then Trichocereus werdermannianus. Maybe he wasn’t sure about the ID, called it Tr. giganteus and changed it to Tr. werdermannianus later on. Both plants are collected in Otavi, Bolivia. Giganteus at 3200 Meters and Werdermannianus at 3500m.  Pics: MUTANT.

I own a Trichocereus giganteus KK1094, which ended up being a completely typical Trichocereus werdermannianus.

trockenen interandinen Tälern der Departements Potosi und Chuquisaca, auf
ca. 2600 m Durchschnittshöhe der Vorkommen) (Abb. 1054—1055). Während Trichocereus validus und T. terscheckii seitlich ± weit herab blühen,
ist T. werdermannianus durch seine nur hochsitzenden Bl. eindeutig unterschieden.
Sie alle scheinen nach den viel längeren Bl. und der sich nie verändernden
Stachelbildung an den Spitzen großer Pflanzen echt trichocereoide Riesenformen
zu sein, die (zum Teil) auch nachts geöffnete Bl. zeigen, wie ich zumindest an zwei
Arten beobachtete.
„Trichocereus pasacana“ dagegen scheint die größten Formen der Helianthocereus-
Formengruppe zu bilden, mit kürzeren Bl., gedrungeneren Röhren und an
alten Exemplaren bzw. solchen an hohen Standorten mit borstenartig elastischen
St., wie sie den Hochlands-Helianthocereus-Arten eigentümlich sind. Ich habe
daher Trichocereus pasacana auch zu Helianthocereus gestellt. Er ist zudem Tagblüher, soweit bekannt.

Trichocereus litoralis – Echinopsis chiloensis ssp. litoralis

Trichocereus litoralis – Echinopsis chiloensis ssp. litoralis

This beautiful Trichocereus species is definitely closely related to Trichocereus chiloensis and the current taxonomy is treating it as a variety or subspecies to it. Trichocereus litoralis always was a problematic species because there are so many intermediate forms between Trichocereus chiloensis and Trichocereus litoralis that it is extremely difficult to draw the line somewhere. While some treat it as part of Trichocereus chiloensis, some others disagree and treat it as a separate species. Personally, I think that the whole group of plants surrounding Trichocereus chiloensis is very variable and we should simply respect that plants can be related to each other and at the same time, look a little bit different. The species is also very closely related to Trichocereus skottsbergii, which I also regard as a variety of Trichocereus chiloensis/Echinopsis chiloensis.

Origin of E.litoralis:

Chile. Growing mostly around the coast line. Coquimbo

Synonyms of T.litoralis:

Echinopsis litoralis, Cereus litoralis, Trichocereus chiloensis var. litoralis, Trichocereus chilensis var. litoralis, Cereus chilensis,

The type location is in Zapallar, north of Valparaiso near the coast of Chile. The species is widely distributed all across the coast up to Los Vilos. The many radial spines are needle-like, while the middle spines are pretty strong and thick and up to 3 cm long. It has 9-28 radial spines and 3-6 middle spines.

Trichocereus chiloensis ssp. litoralis gets between 1-2 meters tall. It has a very dark green color and and a maximum diameter of 10-15 centimeters.

Ribs of Echinopsis chiloensis ssp.litoralis:

15-22, areoles approximately 1-2 centimeters apart of each other.

Flowers of Trichocereus litoralis:

Trichocereus litoralis has a white flower, which is extremely similar to the one on Trichocereus chiloensis. The flowers are up to 15 centimeters long, which is on the lower end of the scale for Trichocerei.

Fruit of E.litoralis:

Round, dark green. Up to 5 Centimeters in diameter

Where to buy seeds and cuttings of Trichocereus litoralis?

Trichocereus tarmaensis / Echinopsis tarmaensis

Trichocereus tarmaensis / Echinopsis tarmaensis

Trichocereus tarmaensis Rauh & Backeberg – Deser. Cact. Nov. 20. 1956

Trichocereus tarmaensis is a close relative of Trichocereus cuzcoensis that was described as a separate species. There are various differences between Trichocereus cuzcoensis and Trichocereus tarmaensis, and some forms of Trichocereus knuthianus are considered to be synonymous with Trichocereus tarmaensis as well.

Echinopsis tarmaensis Tarma Trichocereus tarmaensis

Trichocereus tarmaensis reaches a size of 2 meters and is pupping from the base. It has 7-9 ribs that are approximately 2 centimeters wide, rounded at the top and with very distinct V-notches above the areoles. The areoles are approx. 2-2,5 centimeters apart with a diameter of 9 millimeters. Young growth areoles have a very fine brown wool that changes it´s color to a darker brown. It has 3-6 radial spines that are between 1 and 3 cm long. It often has one very large downward pointing spine that is up to 10 centimeters long. The plant usually has one of those middle spines. Old spine growth changes its color very soon to a gray, similar to what we know from Trichocereus cuzcoensis.

Flower of E.tarmaensis:

White, very similar or identical to some of the spiny forms of Trichocereus cuzcoensis or  Trichocereus peruvianus. The tube has brown hairs and the fruit reaches a maximum diameter of 5 centimeters.

Type location:

Central peru, Tarma in Peru at around 3000 meters.

Trichocereus tarmaensis looks very similar to Trichocereus tulhyacensis and both species are hard to distinguish if do not have the luck to observe them during the flowering phase . The flower of Trichocereus tulhuyacensis is pink, which is something that does not apply to any other Trichocereus species from this complex. If your Trichocereus has a reddish to pink flower, it´s not Trichocereus tarmaensis but Trichocereus tulhuyacensis or another close relative. Both Trichocereus tarmaensis and Trichocereus tulhuayacensis are very rare and mislabeled anyways. Karel Knize is selling seed of this type under the name KK2148 Trichocereus tarmaensis .

SAB Trichocereus Tarmaensis KK2148 Echinopsis tarmaensis knize

When looking at this pic, it gets obvious that this type is VERY similar to some types of Trichocereus cuzcoensis, and even has similarities to a KK242. I do not think that specimens of KK2148  could be recognized as such without knowing the label. They are simply synonymous with some types of Trichocereus cuzcoensis. This species grows at around 3000 meters altitude.

Trichocereus knuthianus (Echinopsis knuthiana)

Trichocereus knuthianus (Echinopsis knuthiana)

Trichocereus knuthianus is a plant that can be found in many parts of Peru. As a species, it is much more diverse than the clone that it is mostly reduced to and there are various forms that belong into the context of Trichocereus knuthianus.  In addition, there are intermediates with Trichocereus schoenii, Trichocereus tarmaensis and Trichocereus cuzcoensis.

Alternative name: Echinopsis knuthiana

Synonyms: Trichocereus knuthiana, Trichocereus knuthianus, Trichocereus cuzcoensis var. knuthianus, Cereus knuthianus, Azureocereus deflexispinus, Cereus deflexispinus, Trichocereus tarmaensis, Trichocereus peruvianus var. Tarma, Trichocereus crassiarboreus, Trichocereus schoenii, Echinopsis schoenii, Echinopsi tarmaensis (not all, but some of them clearly belong into the knuthianus context as well)

Though Trichocereus knuthianus is still considered a correct species with the name Echinopsis knuthiana, it is closely related to Trichocereus cuzcoensis and Trichocereus peruvianus. There was never any good DNA testing done to verify or question this, which is why it is on our short list of species that we´ll test for our upcoming book on the genus Trichocereus. In my opinion, it is a relative of Trichocereus cuzcoensis. We will find out how related exactly once we´ve ran some tests.

Trichocereus knuthianus was discovered and described by Curt Backeberg on the upper course of the Rio Marañon. The plant was named after Graf F.M.Knuth, who was Curt Backeberg´s co-author in the book KAKTUS ABC and a financier for some of his trips.

Rio Maranon Peru Trichocereus knuthianus Echinopsis knuthiana

Most plants that are available on the open market were originally sourced from Friedrich Ritters Seed list. Ritter´s collection number of Trichocereus knuthianus was FR567, sometimes also labeled as Trichocereus knuthianus f. pachanoi or Trichocereus knuthianus FR 677! This strain can be found in collections throughout the World though it is most common in Australia.

Ritter wrote that it´s probably synonymous with Trichocereus tarmaensis and I agree to a certain degree. In addition, he shared the opinion that Trichocereus knuthianus is actually a variety of Trichocereus cuzcoensis, which is most likely correct as well. Trichocereus cuzcoensis only grows in Cusco, but its close relatives grow all over Peru, e.g. Trichocereus tarmaensis, Trichocereus schoenii, etc.

Curt Backeberg, on the other hand did absolutely not agree with Ritter´s attempt to nullify Backeberg´s species, as it would mean that his newly described “species” would´ve become invalid. Generally speaking, Friedrich Ritter knew that plant very well .

Mature plants of Echinopsis knuthiana in habitat tend to have that tree-like rounded log-shape that you can observe on Trichocereus cuzcoensis too. Most other Trichocereus species do not form such  a rounded and tree-like stump, which is another indicator for its genetic proximity to the Cuzcoensis complex.

Trichocereus knuthianus is very widespread and grows in Central Peru and some Departments that surround it.

Trichocereus huascha (Echinopsis huascha)

Trichocereus huascha (Echinopsis huascha)

Trichocereus huascha, also known as Echinopsis huascha, is an Argentinian Trichocereus species that looks very similar to Trichocereus spachianus, Trichocereus grandiflorus, Trichocereus shaferi and Trichocereus schickendantzii. However, there are important differences to distinguish them.

Trichocereus huascha has had a long history with many name changes due to its unique position between Trichocereus, Lobivia and Echinopsis. Friedrich & Rowley renamed it to Echinopsis huascha in 1974 but their actions weren´t really embraced with love.

I have some fresh seeds of Echinopsis huascha. You can get them here:

Synonyms: Lobivia huascha, Helianthocereus huascha, Trichocereus huascha, Echinopsis huascha, Soehrensia huascha, Cereus huascha, Cereus huascha variety flaviflorus, Cereus huascha var. rubriflorus, Lobivia purpureominata, Trichocereus andalgalensis, Echinopsis andalgalensis, Lobivia andalgalensis, Trichocereus grandiflorus, Echinopsis grandiflora,

Described varieties of T.huascha:

Trichocereus huascha v. robustior or robusta

Trichocereus huascha v. pecheterianus

Trichocereus huascha v. rubriflorus 

Trichocereus huascha v. auricolor 

The list of names that Trichocereus huascha already had does not fit on one page, so I will only keep the most important ones. Many varieties of this species were actually labeled Lobivia, Cereus or even Chamaecereus and it´s very difficult to differentiate the plant from similar plants like Trichocereus schickendantzii, Trichocereus spachianus or Trichocereus grandiflorus.

Echinopsis huascha usually grows in small, clumping groups that reach up to 1,1 meters in height. It usually pups abundantly and can grow upwards like a columnar cactus or creeping. The pups can get up to 5-6 centimeters in diameter and has up to 15 ribs as a mature plant. The areoles are between 1 cm and 1,5 centimeters apart from each other. There are yellow colored and needle-like spines on each areole. Trichocereus huascha has 10-12 radial spines that are up to 2 centimeters long. The flower color is absolutely variable; also because there are SO many natural and commercial hybrids. This plant is used extensively in Trichocereus hybrid culture and many hybrids that are floating around on the market cant fully be id´d because the offspring can sometimes look very different from the parental generation. The plant flowers from the apex, through the areoles and the flower color can be yellow, red or orange. You can keep it apart from plants like Trichocereus schickendantzii by the color of the flower (Schickendantzii has white flowers) and the thinner growth of E. huascha. The flowers are 6-8 centimeters in diameter and the species is usually dayflowering! They also are sometimes self-sterile, while other forms are self-fertile. You usually need two plants to get seed, but T.huascha hybridizes so easily in nature that there are some plants that form fruit without being pollinated! There are constant arguments about its synonymy with Trichocereus andalgalensis and at the moment, I consider them synonymous. Trichocereus andalgalensis was described as a red flowering variety of T. huascha (T. huascha v.rubriflorus), but since there are also yellow flowering T. andalgalensis at the original site, this is not really a species that I consider correct.

Origin of Trichocereus huascha:

Argentina. Very widely distributed and can be found almost everywhere around Catamarca & La Rioja. The plant grows at 900-2000 meters altitude.

Trichocereus smrzianus / Echinopsis smrziana

Trichocereus smrzianus / Echinopsis smrziana

Backeberg described Trichocereus smrzianus / Echinopsis smrziana in his KAKTUS ABC, a book that did not get a very wide release. Besides the description is highly controversial because it basically re-describes various forms of Echinopsis schickendantzii / Trichocereus schickendantzii and Trichocereus walteri that are barely on the level of a regional form.

Synonyms: Trichocereus smrzianus, Soehrensia smrziana, Soehrensia smrzianus, Echinopsis smrzianus, Echinopsis smrziana, Trichocereus schickendantzii, Echinopsis schickendantzii, Trichocereus walteri, Echinopsis walteri, etc.

Origin of Trichocereus smrzianus:

Argentina, Salta

Description of Echinopsis smrziana:

This species grows alone or in groups of larger clusters. It has a large, round body and reaches a maximum diameter of 2 meters and can get up to 60-70 centimeters tall. The plant is extremely variable and can grow like a clustering cactus like Trichocereus schickendantzii or in a columnar way, very similar to Trichocereus spachianus. It has 10-15 ribs and only grows at one location, which was also described as the type locality. T.smrzianus is extremely rare, though it is sometimes available on the commercial and sometimes shows up in cactus collections. The fact that the plant has so many ribs, makes it distinguishable from plants like Trichocereus candicans or Trichocereus spachianus. Young plants can look almost identical though, which is why identification of this species should not be done on juvenile plants. The bigger the plants, the broader the ribs are, what gives it a very typical Soehrensia look and it looks much closer to Soehrensia than to Trichocereus.

Spines of T.smrzianus:

The very thin spines are usually yellow to white. Plants have 8-15 spines on one areole, but Trichocereus smrzianus is extremely variable, what makes it so hard to ID. If you encounter the plants in the field it should be fairly easy to identify because it only grows on one location in Chachipampa, Argentina. It has 1-4 middle spines that are up to 3 centimeters long.

Flowers of E.smrziana:

Trichocereus smrzianus has white flowers, almost identical to the ones on T. schickendantzii. Overall it is a form of the latter, which means it is very hard to distinguish it from it. The plant flowers from the upper part of the body, what you can see on the featured image very well. The flowers get between 10-20 centimeters long and look very similar to the ones on Trichocereus tarijensis.

Fruit:

Trichocereus smrzianus has a round, green fruit that is between 2-5 centimeters in diameter and tastes very nicely. The name is a really bad example of how a name should not be. Not sure how it sounds in your language but in mine it sounds like having a seizure while biting your tongue off.
The taxonomic status of this group of plants was very inconsistent and due to the fact that there is a relationship to the genus Soehrensia, taxonomists have moved them back and forth from Trichocereus to, Soehrensia and Echinopsis now. After the merger with Echinopsis, taxonomy went full circle and re-declared Soehrensia as an accepted genus and it seems like it might stay like that. However, the plant is definitely close to Trichocereus schickendantzii and it´s definitely possible that Trichocereus smrzianus is just a natural hybrid between Trichocereus schickendantzii and a different species like Trichocereus tarijensis, or a regional form of the Trichocereus schickendantzii group.

Trichocereus glaucus – Echinopsis glauca

Trichocereus glaucus – Echinopsis glauca

Trichocereus glaucus, also known as Echinopsis glauca, is a Peruvian Trichocereus species described by Friedrich Ritter.

Trichocereus glaucus Echinopsis glauca Friedrich Ritter original photo

Friedrich Ritter original photo

Trichocereus glaucus – Foto: Friedrich Ritter

Origin of Trichocereus glaucus:

Peru ( South Peru ), Arequipa (Rio Tambo), Chile. In Chile, this plant is closely related to Trichocereus fulvilanus and Trichocereus deserticolus.

Description of Trichocereus glaucus / Echinopsis glauca:

Trichocereus glaucus Echinopsis glauca Auxin photo

Trichocereus glaucus can get between 1,5-2 meters tall and is a prostrate/creeping species that you often find hanging down slopes and cliffs. This trait is very distinct in the variety Trichocereus glaucus var. pendens. The color of the skin is very glaucous and small specimens look absolutely like the type of plants that are labeled Trichocereus macrogonus / Echinopsis macrogona today.  Spiny, dark blue versions from the complex around T. peruvianus. However, macrogonus grows columnar while this species tends to bend over with age. New growth is very glaucous.

Areoles of Echinopsis glauca:

The areoles are dark brown to gray in color and approximately 2,5 centimeters apart of each other. Similar to other plants related to Trichocereus peruvianus, the plant has a diameter of up to 10 centimeters and the areoles are gray felted. The spines look a bit like the ones on Trichocereus cuzcoensis and old growth has a typical satin white glow that is common on this species. Trichocereus glaucus has 6-9 ribs, 3-6 middle spines and 8-11 radial spines. The middle spines are 5-10 centimeters and the radial spines 1-2 centimeters long.  New spine growth is black to brown and turns gray with age.

Flowers of T. glaucus:

White, just like almost every other Trichocereus from this complex. The diameter is very variable and usually is between 15-22 centimeters. Trichocereus glaucus is a night-flowering species with green, round fruits. However, the hairy flowers usually stay open until the next morning.

Fruit of E. glauca:

Round, green, and 3 centimeters thick.

Type locality: Lower part of the Rio Tambo in the department Arequipa.

Trichocereus glaucus is very similar to Trichocereus chalaensis and grows in a similar way. We think that Trichocereus chalaensis might be synonymous with Ritter´s Trichocereus glaucus. Ritter´s field number of Trichocereus glaucus was FR270. We distributed seeds of Trichocereus glaucus various times in the past and all ended up amazingly beautiful. It´s a very nice species.

Buy Trichocereus glaucus seeds:

Trichocereus glaucus aka Echinopsis glauca is extremely rare and most plants on the market will probably come labeled as “Trichocereus peruvianus” or “Trichocereus macrogonus”. It is common occurence for some Peruvian cactus collectors to label all glaucous Trichocereus species with this name. This is obviously wrong and causes chaos. We sometimes have plants of this species in our Trichocereus Facebook group, which can be found here: https://facebook.com/groups/trichocereus

Cultivation of Echinopsis glauca:

Trichocereus glaucus is a very resilient grower and likes to be watered well in summer. In winter, they should be kept as dry as possible at around 10° Celsius. Seed germinates very well and the plant is usually very tough. That´s also caused by its drought tolerance, which is very typical for these kinds of plants. The species will probably tolerate temperatures between -5° to -7° Celsius over very short time, but I would not stress it and this also depends on many other factors, like general health and dryness. I would recommend keeping at no lower than 10° Celsius in winter.

Varieties of E. glauca: Trichocereus glaucus var. pendens. This variety does only grow hanging down cliffs and small hills. This variety only grows at one location in Chile and is extremely rare. This local population is in the south of Arica, Camarca in Chile. Backeberg suggested that this would be his Trichocereus uyumpaensis, but Friedrich Ritter vehemently disagreed with that. More information is necessary about this topic.

Translation of Ritter´s description (loosely)

This species forms shrubs the size of 1 – 2 meters and often several meters in diameter, sprouting mainly from shoots that lay sideways on the ground. This plant rarely pups from the top or upper parts. The shoots are 5 – 8 inches thick, erect, later lying in the lower parts, the new shoot blue-green, later gray-green.

Ribs: 7-9, very broad, obtuse, 7.5 to 13 mm high, 15-25 mm wide, notched, with transverse furrows that do not reach down to the separating grooves of the ribs,
areoles: grey felted, 1/2-3/4 inches in diameter, 1 to 2 inches free removal, let down by the humps in the notches
Spines: In the new shoot black to brown, becoming gray, straight, rigid
Marginal spines: 7-10, directed laterally, the lower and lateral 8 to 15 mm long, coarse needle-shaped, somewhat flattened, the upper the upper stronger and not sharply separated from the Central spines.
Central spines: 3-6, very spread apart, subulate in the middle, but usually closer to the top edge and almost in the position of an edge of spine, below 1.5 mm thick
Flower: Not far from the apex, 13 to 19 centimeters long, fragrant, opening in the evening, the morning still open,
Ovary: Green with fleshy green, narrowly triangular, 2-5 mm long, pointed scales and large scales raised bases. The flowers are covered with brown/black hairs.
Partition against the nectar chamber 3-4 mm thick, tube-shaped, 13 to 23 mm long, to the stylus 1to 2 mm wide, brownish, almost openly, with nectar

Tubes:

In addition funnel shaped, 40-65 mm long, the top 2 to 3 cm wide, pale green interior, exterior gray-green, with triangular points, 7.5 to 10 mm long, dark green scales and tufts of hair as on the ovary.
Stamens: white, greenish below, insertions missing on the top 2 to 3 centimeters of the tube to a ring on the hem, pouch pale brown, approximately at half height petals standing
Stylus: pale green, white or pale brownish above, 10 to 11 cm in length, with 14 to 18 mm fall on the 13-16 spread pale yellow stigma lobes, between the pouches or outstanding.

Trichocereus scopulicola / Echinopsis scopulicola

Trichocereus scopulicola / Echinopsis scopulicola

Trichocereus scopulicola is a Bolivian Trichocereus species.

Trichocereus scopulicola FR991 Rod

Trichocereus scopulicola FR991 (Rodni Kisar)

Synonyms of Trichocereus scopulicola:

Echinopsis scopulicola, Trichocereus cv. Super Pedro, Trichocereus scopulicolus, Trichocereus scopulicola NMCR, Trichocereus cordobensis, Trichocereus crassicostatus, Scop,

Origin:

Trichocereus scopulicola was discovered by Friedrich Ritter during one of his expeditions to Bolivia in 1959. The location of the type is Tarija, Bolivia. More precisely, Ritter gave Tapecua as the location and assigned the collection number FR991 and sold seed of his discovery through his legendary Winter Seed lists. Because of that, he helped spreading the plant all over the world, despite the fact that Trichocereus sScopulicola is really rare in nature. There are very few collections of this plant in nature and I am always interested in obtaining seed from new scopulicola types. The plant grows in Tarija in the province O Connor. And no, this has nothing to do with Sarah Connor from the movie TERMINATOR. Trichocereus scopulicola grows in the cactus forests around the Department Tarija at around 1000-1500 meters.

Description of Trichocereus scopulicola:

Trichocereus scopulicola grows columnar like a tree and pups from the base. But it´s actually rare for this plant to produce numerous shoots and most plants don´t have any side shoots. Trichocereus scopulicola can get up to 4 meters tall though most specimens are smaller. The columns are between 5-10 centimeters in diameter and have a nice, dark green epidermis.

Ribs:

Trichocereus scopulicola can have 4-6 ribs though most specimens have five. The areoles are furrowed. The areoles are sunk in and have very little white fluff/wool on top of them. The areoles are rounded or oval and are between 1-4 mm long and 1-2 mm broad, which is very small for a Trichocereus. The distance between the areoles is between 15 and 30 mm. Areoles that form flowers have 4-5 mm diameter. Large, adult plants often lack the spines, while very young seedlings look remarkably similar to a Trichocereus pachanoi and can only be differentiated by the weird rib shape of Trichocereus scopulicola. Adult plants have (if they have any) 3-6 spines that are very small and up to 1.5 mm long. Seedlings have 6-7 ribs, areoles up to 2 mm in diameter and 3-5 mm away from each other, 7-14 needle-like spines (2-3mm long), of which two are central spines.

Flower of Echinopsis scopulicola:

Trichocereus scopulicola flowers from the apex but there are plants where the flowers come out from lower points on the plant. The flower is white and between 15-22 centimeters long. Trichocereus scopulicola is a night-flowering species but the flowers stay open until the late morning.

Fruit:

The fruit of Trichocereus scopulicola is green and can get up to 6 centimeters thick.

Friedrich Ritter considered this species to be very close to Trichocereus bridgesii, which is one of the plants that grow in the neighborhood of Trichocereus scopulicola. And it´s very likely that Tr. scopulicola is some kind of natural hybrid involving Trichocereus bridgesii or Trichocereus pachanoi.

In addition, Ritter wrote that Trichocereus riomizquensis is related to it, but not as closely related as Trichocereus crassicostatus is. These days, Trichocereus crassicostatus is generally seen as a synonym of Trichocereus scopulicola or Tr. pachanoi. So far, I´ve not been able to track a specimen down but they are certainly out there. If you grow one, let me know.

Cultivation of Trichocereus scopulicola:

Trichocereus scopulicola is similarly tough as Trichocereus bridgesii. The reason is simple; both come from Bolivia and are used to the same conditions. Bolivian Trichocereus species are very drought resistant, but can also deal with strong rainfalls in summer pretty flawlessly. However, they should not be watered when it´s cold and they prefer a purely mineral soil mix because that dries up a lot faster. During the hot summer season, they can be watered every few days when the soil has dried up again. Don´t water them when it´s cold or rainy because that can cause rot.

Winter protection and Minimum Temperature:

Scops are relatively hardy and can short night frosts of down to -5° Celsius and maybe even lower than that, but I would not test it out because low temps weaken the plants. The minimum average temperature should be around 10° Celsius and they should be completely dry over winter if you take the plants inside. If the get wet over a prolonged period of time, it can cause root rot or other infections.

Seed & live cuttings:

I get seeds every now and then and I know a couple of growers who actively breed with Scops. There sometimes are some available at SAB and the SAB forum. Besides, Misplant makes a couple Scop Crosses a year. This year, he made a pretty cool cross between a Scop and a colored Grandiflorus, which I can wholeheartedly recommend you because it might produce Scop seedlings with a colored flower.

Trichocereus scopulicola can be used as a grafting stock. It is a great stock that accepts graftings very easily.
