Trichocereus Facebook Group Echinopsis Growers Worldwide

Trichocereus Facebook Group Echinopsis Growers Worldwide

Hi guys, today I wanted to give you a preview from our Trichocereus Facebook group called Trichocereus & Echinopsis growers worldwide. It is one of the oldest Trichocereus groups on Facebook and was funded sometime around 2014.

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.

Orignal description of Curt Backeberg in German:

kaum unterschieden, bis 7 cm lang, gelblich bis bräunlichgelb bzw. hornfarbig;
Bl., wenn zahlreich vorhanden, ± kranzförmig um den Scheitel oder scheitelnah;
bis 20 cm lang; Gr. weiß, kaum die Staubb. überragend; N. 15—19; Fr. kugelig,
3,5 cm ∅, lange, aber nicht sehr zahlreiche schwarze und weiße Haare tragend;
S. 1,3 mm groß, mützenartig, rauh punktiert. — B o l i v i e n (von mir, als Typort,
im Charcoma-Tal, östlich von Tupiza gefunden, von Cardenas auch in den
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?

You can get some seeds of Trichocereus litoralis in my shop.

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 .

This picture shows a seedgrown specimen that was sold through the SAB shop in Australia.

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 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.

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 santaensis / Echinopsis santaensis descriptions

Trichocereus santaensis / Echinopsis santaensis descriptions

Trichocereus santaensis is columnar cactus and species described by Curt Backeberg and Werner Rauh. It is endemic to the Santa Valley in Peru. There are many different forms that belong into the larger context of T. santaensis, e.g. Trichocereus sp. Chavin de Huantar also known as El Lanzon, Trichocereus huanucoensis, Trichocereus pallarensis and many others.

Trichocereus santaensis Chavin de Huantar Echinopsis Chavin Herbalists

Echinopsis santaensis Trichocereus santaensis Rio Santa Peru Valley

Origin of Trichocereus santaensis

Northern Peru, the valley around the Rio Santa, Puente, Bedoya, Huayanca

Can be kept apart from Trichocereus cuzcoensis by the absence of swollen spine bases. It also has a more frosted blue skin color, has fewer spines and shorter middle spines. Unlike Trichocereus peruvianus, it grows always columnar and does not grow prostrate.

trichocereus santaensis Huntington Botanical Garden Echinopsis santaensis HBGTrichocereus Santaensis – Huntington Botanical Garden – by Richard Hipp!

Description of Trichocereus santaensis Rauh & backb g -. Descr. Cact. Nov. 20, 1956

Trichocereus santaensis can get up to five meters high and branches from the bottom. The stems are blue-green to a glaucous green. It has 7-9 ribs that are similarly broad than the ones on Trichocereus knuthianus aka Echinopsis knuthiana. There is a distinct furrow above the areoles. This distinct V-Notch is very strong in young pups. The areoles have a diameter of approximately 1 centimeter and Trichocereus santaensis has between 1-3 radial spines. Spines medium long to short. In addition, Trichocereus santaensis has one very long middle spine, which is up to 5 centimeters long.

Flower: The flower is white and gets up to 22 centimeters in length. It has a similar flower than other San Pedro types, which is another indicator that Trichocereus santaensis is just a regional form of another species, e.g. T. pachanoi or T. peruvianus.

Origin/Habitat: Rio Santa, Puente, Huayacana, Bedoya.

Trichocereus santaensis is very similar to Trichocereus cuzcoensis and is constantly confused with it. However, it does NOT have rounded, knobby spine basesBesides, the spination is less strong and grows always columnar instead of creeping. Today, the species would probably not be considered to be correct and extensive DNA testing is necessary to look into the limits of this species and where other species begin.

Please note that T. santaensis is very variable due to the high number of regional forms. Some of which have red spines, some with yellow spines and some where the spines are completely absent.

trichocereus santaensis Echinopsis santaensis Rio Santa

 

In the Chapter of Trichocereus peruvianus, Backeberg wrote about its growth type:

I even found the Type initially growing erect, then lying or hanging . But near Matucana (Sic!), there also are upright growing varities of Trichocereus santaensis, which probably weren´t recognized as a seperate species.
The identification of these species with Tr. macrogonus (KKDE., 20, 1941) i cannot agree with. 
However, I definitely think that some of the more spiny forms of T. santaensis could´ve been the lost T. macrogonus. Some of them are extremely spiny.

Trichocereus vollianus / Echinopsis volliana

Trichocereus vollianus / Echinopsis volliana

Trichocereus vollianus, also known under it´s currently valid name Echinopsis volliana, is a columnar cactus from the genus Trichocereus. It is a very interesting plant and there is only little information to be found about it. Ben Kamm and Sacred Succulents encountered Trichocereus vollianus during their 2010 Sacred Succulents field trip.

The original description of this plant came from Backeberg in his book KAKTUS-ABC. The original type location is in Arque in Cochabamba. The shoots have a maximum diameter of up to 10 centimeters, approximately 13 ribs and a very bright green yellow color. The epidermis of this plant has similarities to Trichocereus spachianus, which has a very bright green color too. The ribs are 7 mm broad and are up to 5 mm high. The areoles are approx. 2-2,5 cm apart from each other. The plant has 7-12 radial spines and very fine and thin spines that can get up to 7 mm long. There usually is only one middle spine which can reach a length of 2,5 cm. All spines are yellow colored (Backeberg used the term “Amber”).

Flowers: The flowers of Trichocereus vollianus are white and up to 12 cm long. However, I assume that the flowers depend greatly on the health of the plant and larger flowers wouldn’t come as a surprise to me.

Fruit: Green and very hairy.

How to keep it apart from Trichocereus spachianus?: Trichocereus vollianus is very similar to Trichocereus spachianus but thicker, even more shiny and has a brighter green epidermis. Backeberg also mentioned that they work very well as a grafting stock.

There also was a Trichocereus vollianus var. rubrispinus with reddish spines, which would probably be regarded as nothing but a regional form under today´s standards. It is a common occurrence that some populations are extremely variable with lots of different forms growing together and it is not enough to warrant a separate description as a new species.

Where to get seeds of Trichocereus vollianus?: Well, it´s definitely a rare species. Sacred Succulents collected some seeds and gave them away under the name mentioned above but apart from that, there are very few sources that provide viable seed.  You could make a posting in our Trichocereus Facebook group because I know of some people who were able to get some seeds back when they were sold by Sacred Succulents. Definitely an interesting plant!

Misidentified Trichocereus vollianus in Australia:

There are a whole lot of misidentified plants of this species going around in Australia. These are probably either Trichocereus thelegonoides or Trichocereus quadratiumbonatum. If your Trichocereus  vollianus has strong ridges/notches above the areoles, it is not the right species.

Trichocereus shaferi (Echinopsis shaferi)

Trichocereus shaferi (Echinopsis shaferi)

The name Trichocereus shaferi was described by Britton and Rose in the 1920s and lacked some important information. However, there were some later descriptions by Friedrich Ritter, Curt Backeberg/Rauh and Werdermann that went more into detail.

Trichocereus shaferi pups from the base and reaches a size of 1-1,5 meters. The plant grows halfway prostrate or leaning over and has between 15 and 20 ribs. Britton and Rose gave an average number of 12 ribs, which is dramatically different from the data that were given in later descriptions. The maximum diameter is 5-12 centimeters and the color is a gray/dark green, which you can very well see on the pictures that were provided by Trout. The ribs are 0,5-1 centimeters high and there are substantial furrows .

The areoles on Trichocereus shaferi are white felted and 1-6 mm in diameter and up to 1,2 centimeters apart of each other.

Spines: The spines of Trichocereus shaferi are yellow, very fine and needle-like with a slightly dark-brown tip. It has 7-10 radial spines (up to 1 cm long) and 1-3 middle spines (1-2 cm).

Flower: Very round flower. White. Trichocereus shaferi flowers from the upper part/apex and Britton and Rose gave a size of 15-18 cm.

Fruit: The fruit has very dominant white hairs, as you can beautifully see on the second picture. The edible fruit is round and 3-5 cm in diameter. Green in color with reddish/green scales.

Origin: Ritter encountered this plant near Leon near Jujuy at around 1500-1800 meters growing on rocky slopes. Britton and Rose gave San Lorenzo in the provence Salta at 1800 meters as the location of the typus. Ritter considered his collection in jujuy to be a regional variety but didnt really follow up on it. His collection name was FR41 and there is a large number of seeds that gotten into the collections of cactus fans all around the world.

Where to buy seeds and plants of Trichocereus shaferi? Well, it´s rare and you might come across them on eBay. Like I already mentioned before, I bought a large plant with this name a few years ago and we´re waiting for it to flower next year. Some seed stores and cactus nurseries have them in stock every once in a while, but it´s a rather rare species and it´s not available from South America. I am sure there are some collectors that offer seeds from their collections sometimes, but it´s probably a little bit hard to find and luck has a lot to do with it. If I´d be looking for this species, I´d write emails to Kakteen Haage, Kakteen Uhlig, Succeed, Sacred Succulents and hope for the best. You can also try making a post in our Trichocereus Facebook group but I´ve never really encountered one there. But it cant hurt to ask.
