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.

KK1421 Trichocereus cephalomacrostibas cv. Rio Tambo

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.

I guess the deeper I get into the rabbit hole, the more I appreciate the Peruvian Haageocereus species. Those members of the Trichocereeae are amazing columnar cacti that are very similar to Trichocereus. The whole genus is poorly understood, but there has be some amazing work done in the past years.

So yeah, long story short…I stocked some Haageocereus species and I am sure a lot of you will apreciate them! Most if not all Haageocereus species are CITES 2 and can be shipped as seeds into most countries. I´d also like to mention that some Haageocereus species can´t be imported to Australia because of quarantine, so please make sure to check the permitted species before ordering.

Here is the list of new Haageocereus seeds that I have in stock. Some of those names are no longer considered valid, but I stocked them under the name that I got them with.

All Haageocereus seeds are very limited and I just have enough for a few orders. All it takes is one big order and I am out of a certain species, so if you are after one don´t wait too long!

Other Cacti from the Sacred Succulents Field Trips

Other Cacti from the Sacred Succulents Field Trips

Hi Guys, in this post I will show you some of the other cacti from the Sacred Succulents Field trips. The copyright of all those pics is: Ben Kamm, Sacredsucculents.com

BK08530.1 Mahueniopsis boliviana, Tambillo, Bolivia

This majestic Mahueniopsis is from Bolivia. Sacred Succulents gave away seeds of that plant, which was visited during the 2008 Sacred Succulent Field Trip

190 BK08530.1 Mahueniopsis boliviana, Tambillo, Bolivia

Haageocereus sp, Matucana, Peru

This very nice Haageocereus grows in Matucana, which is the home of many amazing Trichocereus species as well. There were no seed collected from that species.

 BK09508.4 Borzicactus fieldianus, Chavin, Ancash, Peru

This interesting Borzicactus is definitely a Trichocereus Lookalike that you should have seen. At first, it looked a little big like a Rauhocereus but the strong segmented areoles are a lot more dominant than on other Rauhocereus species. This plant was visited during the 2009 Field Trips!

 Rebutia sp, Rio Lope Mendoza, Cochabamba, Bolivia 2010

Have a look at this barely visible cactus in between rocks and dead plants. That´s a pretty typical Rebutia population and it gives you a better understanding why cacti are sometimes so hard to find. I am pretty sure that there still are a lot of new species out there to be discovered, that are just not visible enough to be found. There were no seeds collection from those plants.
