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.

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.

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 .

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 grandiflorus / rowleyi (Echinopsis grandiflora)

Trichocereus grandiflorus / rowleyi (Echinopsis grandiflora)

Trichocereus grandiflorus is a cactus from the genus Trichocereus. Its status is highly questionable as a correct species and the opinions are as varied as the names it carried. Joel Lodé has listed Trichocereus grandiflorus as Trichocereus rowleyi right now, while Anderson listed it as a synonym of Echinopsis huascha in his Cactus Lexicon. Please note that some people also refer to this plant as Echinopsis grandiflora, but this name is also used by Echinopsis eyriesii v. grandiflora and the older name has priority.

Synonyms of Trichocereus grandiflorus:

Lobivia grandiflora, Lobivia grandiflorus, Helianthocereus grandiflora, Helianthocereus grandiflorus, Helianthocereus huascha, Trichocereus rowleyi, Echinopsis huascha

Trichocereus grandiflorus was moved around between the genera  a lot in the past. It is genetically close to both Lobivia and Soehrensia, which is why it was sometimes included there. Friedrich et al. listed it as Echinopsis grandiflora. Anderson then listed it as a synonym to Echinopsis calochlora in his CACTUS LEXICON. Joel Lodé lists it as Trichocereus rowleyi. Schlumpberger lists it as Soehrensia grandiflora (Schlumpberger).

T.grandiflorus Flower:

The flowers of Trichocereus grandiflorus are often red and/or show various variations of red flowers. There are many hybrids, which is why the flower color is relatively unrelaible. There also are versions of flowers that are white in color and between 15-25 Centimeters in size. The tube is usually very hairy, but there are countless hybrids with all kinds of flower colors available on the open market.

Origin of Trichocereus grandiflorus:

Argentina, especially around Catamarca. The original description refers to a plant from a private collection and it is suspected that Trichocereus grandiflorus is extremely close to Trichocereus huascha and might even be part of this species.

The original description as Lobivia grandiflora came from Britton & Rose. Because of that, the plant was labeled as a Lobivia in most classic cactus literature. In addition, the title “Grandiflorus”, which roughly means “Large Flower” makes a lot of sense because most Lobivias usually have smaller flowers. The large flower size for a Lobivia shows that it is not a very normal Lobivia either. The collector Fric, who labeled it Chamaecereus giganteus (same principle because most Chamaecereus are tiny Lobivia), originally introduced the plant into the market, but since it was so different from Chamaecereus, this did not last long. Backeberg wanted to put it in his own problematic Genus Helianthocereus due to the diurnal flowers, but this flawed system was not adapted. Eventually, the plant ended up in Trichocereus, where it was until the restructuring made by Friedrich et al.

Cultivation of Trichocereus rowleyi (ex GF):

Trichocereus grandiflorus is a very hardy plant that can grow a lot during just one growing season if watered accordingly. The plant is able to tolerate some light frost but I would not recommend trying it out to the limit. I keep them at around 10° Celsius during the wintertime in a bright and well-ventilated room. I do not water them during the wintertime and only start watering again in March.

Buy Trichocereus grandiflorus / Seeds or Plants:

This plant is available every now on then on marketplace sites like Ebay or Amazon. In addition, many growers use it to produce hybrids. The Californian nursery Sacred Succulents has some colored Grandiflora hybrids and they sell seed every now an then. You can also try to make a post at our Trichocereus group at https://facebook.com/groups/trichocereus   because there are some growers there who give some away every now and then.

Trichocereus grandiflorus also shows similarities to Trichocereus schickendantzii and some even consider them close relatives. It´s sometimes difficult to keep the two apart and growers or collectors mix them up all the time. The same applies to Trichocereus huascha, which differs from Trichocereus grandiflorus through its spination.

Due to the fact that there are so many misidentified Trichocereus grandiflorus, or plants that are identified as Trichocereus huascha but are actually GF, a large part of the photos that can be seen online show something else. This whole confusion is worst with small and juvenile plants. Trichocereus grandiflorus is MULTI-Ribbed and grows columnar. Its higher rib count and the strange pupping behavior in combination with shorter spines than T. huascha and its typical pupping style at the base make it possible to identify it reliably though. The pups almost look like little balls on the base of the plant while Trichocereus schickendanzii forms large clusters that can get up to 1-2 meters wide. The problem with Trichocereus grandiflorus is that the original description was written after a collection plant, which may or may not have already been a hybrid of Trichocereus huascha.

Before we get to the pics, let me first take the time to say thank you to Prier, who donated those amazing pics. Thanks Prier!

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.

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.

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 cephalomacrostibas / Echinopsis cephalomcacrostibas Weberbauerocereus

Trichocereus cephalomacrostibas / Echinopsis cephalomcacrostibas Weberbauerocereus

Trichocereus cephalomcarostibas, also known as Echinopsis cephalomacrostibas, is a columnar cactus that was described as a Trichocereus species by Curt Backeberg and Werner Rauh. However, the plant in question later turned out as a Weberbauerocereus and the flower makes it pretty obvious that Echinopsis cephalomacrostibas is not a Trichocereus.

The currently valid name of this species is Echinopsis cephalomacrostibas, but most authors went on to treat it as an incorrect species or move it to Weberbauerocereus as Weberbauerocereus cephalomacrostibas.

The original description of Trichocereus cephalomacrostibas

The original description was published by Backeberg and Werdermann in the book NEUE KAKTEEN, which is German for NEW CACTI. The book was released in 1931. The original description described a plant that was then called cereus cephalomacrostibas. Most plants that are now part of the genus Trichocereus were treated as Cereus at the time, which is why the name wasn’t surprising.

Trichocereus cephalomacrostibas, also known as Echinopsis cephalomacrostibas, gets 1,5 – 2 meters tall and pups have a maximum diameter of 8-12 centimeters. The areoles are very close to each other, which is even more obvious on older plants later on. The areoles are between 1-2 centimeters in diameter and the plant is very spiny. It has up to 20 small radial spines and between 1-3 middle spines that can be up to 14 centimeters long. The spines are dark brown to red brown (old growth gray). It´s noteworthy that the original flower from the Backeberg description only had a size of 12 cm (which would fit here), but was said to have scales on the flower. Besides, it was supposed to be white instead of this cream or beige color.

Origin: South peru, near Mollendo.

Please note that there also is a plant called KK1421 Trichocereus cephalomacrostibas that has nothing to do with this plant anmd, that probably grew on the same site  and was confused with a Trichocereus.

This field collected Trichocereus cephalomacrostibas / Echinopsis cephalomacrostibas is fairly interesting though it probably has nothing in common with the species that it is supposed to be part of. Knize collected this nice strain near the Rio Tambo in Peru. It almost looks like a spiny Trichocereus pachanoi strain and should definitely be investigated some more.

If you compare those two plants to the plant that was originally described as Trichocereus cephalomacrostibas, it gets obvious that they are all different plants. The plant in the link was actually a Weberbauerocereus. The seed and the flower are so unlike the ones on any other Trichocereus that it´s absolutely obvious that it’s not a Trichocereus.  But that’s a different story. The original Trichocereus cephalomacrostibas (you know, the one from the link, which actually is a Weberbauerocereus) is said to grow east of Mollendo in the Department Arequipa and occurs from Chala to the Rio Tambo in the south. And that’s where KK1421 is said to originate from. Rio Tambo.

Case of mistaken identity ?

Just because there are Trichos near the Rio Tambo, it does not make em automatically the same population of this Trichocereus cephalomacrostibas from the description. That´s not Ill will but just the flaws of this particular labeling system. It´s  just natural that you can sometimes find a couple of different plants growing at the same area. And because of that, seed collectors should give every single collection (instead of just the whole collection site) a unique number, so you can easier track them down and see which ones would fit in the descriptions and which ones don´t.

Alright, what does that say about those two different plants labeled as KK1421. Well, very little. Both are interesting Trichocereus and while one of them is definitely a cuzcoensis relative, the other one needs further investigation.

Another KK1421 Trichocereus cephalomacrostibas

The original description goes like this:

Cereus cephalomacrostibas grows in packed groups of columnar cacti that get up to 2 meters tall. They are up to 10 cm thick, a gray-green color, tightly packed areoles, 3 – 6 radial spines and 3 middle spines. The flower is 12 cm long (which is too small for a Trichocereus flower), white, covered with white wool and scales. This original plant occurs in South Peru, above Mollendo.

Now back to KK1421: The Seeds came from Karel Knize and were originally collected from Matarani, Peru at 300m altitude. Knize´s plant obviously comes from the group around Tr. cuzcoensis but it´s difficult to know if this is actually the same plant as Backeberg described as I lack a pic of the flower. What I can say is that 12 cm would be very small of a Trichocereus flower. And there are pics showing a type of Weberbauerocereus, which most believe is THE original Tr. cephalomacrostibas. Mr. Knize´s plant is 100% sure NOT a weberbauerocereus.

Where to buy seeds of KK1421: I actually have some in my shop every now and then. Check it out here: trichocereus.net/shop . This article is an excerpt from my book KAREL KNIZE TRICHOCEREUS FIELD GUIDE.

TBM – Trichocereus bridgesii Clone A + Clone B / Penis Plant aka Penis Cactus

TBM – Trichocereus bridgesii Clone A + Clone B / Penis Plant aka Penis Cactus

The so-called TBM (short for Trichocereus bridgesii monstrosa) is a Trichocereus clone that produces some very typical spineless growth that gave it its name “Penis Plant”.  It forms small & penis-like pups that look like green sausages (or a really small penis) that pup repeatedly over and over again. The fact that the new pups tend to have a small insertion in the middle reinforce this impression.

There are two clones that we know of this well know monstrose:

TBM CLONE A / Trichocereus bridgesii monstrosa Clone A

This version grows like a classic columnar cactus and grows upright columns. This version does not terminate its growth over and over again, and produces regular spines very sporadically. It is almost spineless and forms some blue/green stems with 2-4 flat ribs. In very rare cases, it produces yellow spines that demonstrate that this plant is actually a Trichocereus bridgesii, also known as Echinopsis lageniformis. This type is always mixed up with the smaller version of the penis cactus, Trichocereus bridgesii monstrosa clone B. The columnar version is  much more rare than the smaller TBM Clone B.

TBM CLONE B: Trichocereus bridgesii monstrosa / Echinopsis lageniformis Clone B

This clone has between 2 and 5 ribs and produces some strong spines that are very visible, even on small plants. The pups reach 3″ to 6″ before they terminate their growth and produce a new pup on top of it. This version  is also referred to as TBM Clone 2.

Curt Backeberg claimed to be the source for at least one of the two TBM in his book DIE CACTACEAE. I have no reason to doubt his explanation, as he had the infrastructure to make this plant one of the most common monstroses that it is today.

Where to buy a TBM Clone A or Clone B?

CLONE B is widely available and can be found in cactus collections all over the world. You often come across TBM that are for sale on marketplace sites or classified ads. In Australia, CLONE B is very common while CLONE A is extremely hard to find. There are a handful of growers who got their hands on a Clone A, but almost all plants on the Australian market are Clone B.
