Trichocereus angelesii, also known as Echinopsis angelesii or Echinopsis angelesiae, was originally described by Friedrich Ritter as a white flowering variety ofTrichocereus strigosus / Trichocereus strigonus, until Kiesling publicized it under the name Trichocereus angelesii.

The flower of Trichocereus angelesii
The flower of Echinopsis angelesii is white and 12-24 centimeters long. Trichocereus angelesii is a day flowering / diurnal species with clear visual similarity to Trichocereus strigonus. The spines, fruits and seeds are pretty much indistinguishable from the ones of Trichocereus strigosus, which makes it nearly impossible to identify the plant unless you find it at the original type location. Trichocereus angelesii, aka Echinopsis angelesii, usually has 14-22 ribs . In comparison to this, Trichocereus huascha has 12-15 ribs.
The typus location is Famatima in the provence La Rioja, what makes it likely that it is synonymous with the commercial name Trichocereus famatinensis. It is also closely related to the plant that Ritter called Trichocereus callianthus. This plant was originally sold by Ritter as FR999, which was still labeled as Trichocereus huascha back then.
Kiesling´s description gives Darwinia in Argentina as the typus location and it´s not clear whether or not those plants were actually the same.
Buy Trichocereus angelesii / Buy seeds of T. angelesii
It´s a rare species that you only get rarely, but classic Kaktus nurseries like Kakteen Haage or Uhlig Kakteen might have some of them available. If you don’t have the chance to collect them at one of the aforementioned locations, you will probably not run into it very oftenly. There are also some older plants that you can find on the commercial market, and these are usually labeled as T. huascha or Trichocereus strigonus. White flowering Trichocereus huascha might very well be a mislabeled Trichocereus angelesii.
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:
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.

This plant looks more like a Trichocereus candicans, but I am still keeping it here for now because it´s from a botanical garden and it migt actually be a hybrid between these two species. Photo by Cliff from Arlington, Virginia, USA Echinopsis huascha

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 andalgalensis has a weird & complicated history. The name first appeared in 1893 in the MONATSZEITSCHRIFT FÜR KAKTEENKUNDE, which is a German publication about cacti. The plant was originally introduced into the world of taxonomy as a red flowering variety of Cereus huascha (Trichocereus huascha). In his book, Schuman mentioned that Weber described this plant and regard the red flowering variety of Cereus huascha (now Trichocereus huascha) to be a separate species called Cereus andalgalensis. The plant is very similar to Trichocereus huascha and was recently declared to be synonymous with Trichocereus huascha. The current taxonomy tends to merge relative plants together in larger, more variable species and I absolutely agree with that. The species was originally found near Andalgala, has very fine yellow spines and is sprouting from the base.
Synonyms: Echinopsis andalgalensis, Lobivia andalgalensis, Cereus andalgalensis, Cereus huascha var. rubriflorus, Trichocereus huascha var. rubriflorus
Now back to the time when Cereus andalgalensis was first desctribed. Back then, a cactus enthusiast and taxonomist called Spegazzini somehow got the idea that the name Cereus andalgalensis would actually be about a small Lobivia that was found near Ancasti. Which was absolutely not the case, since Trichocereus Andalgalensis is a columnar cactus that grows very much like Trichocereus Huascha (but does not get as big) and not a small clumping Lobivia.
And when Britton & Rose wrote their cactus manifest called THE CACTACEAE, they did not realize that Spegazzini described a completely different plant and published the troubled description in their as Lobivia andalgalensis B&R and declared that Lobivia to be synonymous with the red flowering variety of Trichocereus huascha (Trichocereus andalgalensis), which back then was called Cereus huascha Rubriflorus. Now, there were two different plants that were considered to be the same plant. And one (the Lobivia) did absolutely not fit into Weber´s old description of a columnar cactus. Weber originally gave Andalgala in the province Catamarca to be the type location of the plant. Exactly where Rauh found a small clustering Trichocereus that fit into Webers old description and which was most likely the original origin of Trichocereus andalgalensis, which was back then still called Cereus andalgalensis.
Description: Trichocereus andalagensis is bright green in color and reaches a maximum diameter of up to 6 centimeters. The shoots can reach a maximum height of 10-40 Centimeters. It´s pretty typical for this plant to sprout abundantly from the base, even at a relatively young age.
Ribs: Trichocereus andalgalensis has 10-18 Ribs that are up to 5 mm high and between 5-10 mm wide. The areoles are brown and declining in color with age. The areoles are between 1-3 mm in diameter and 5-10 mm apart of each other.
Spines: The spines of Trichocereus andalgalensis are yellow, very similar as the ones on Trichocereus spachianus. All spines are very fine and needle-like. It has 7-15 radial spines that can get up to 1,5 mm long and 1-2 middle spines, which are 1-4 cm long.
Flowers: The flowers are usually red and up to 8,5 cm long, what makes the flower of Trichocereus andalgalensis one of the smallest flowers on a Trichocereus species. The flowers are and have a lot of brown hairs. There also is a variety with a yellow flower. The yellow variety is called Trichocereus andalgalensis var. flaviflorus and the red flowering one is Trichocereus andalgalensis var. rubriflorus.
Where to buy seeds or plants of Trichocereus andalgalensis?: There only are a couple of sources where you can get seeds of Trichocereus andalgalensis. One is Sacred Succulents, which was offering very viable seeds of this amazing cactus. Köhres has them in stock sometimes too though I have no idea how the germination rate of those is. Apart from that, I am not aware of any commercial sources that sell this seed. If you have a shop and have them in stock, you can let me know and I´ll add you to this page. You can also make a posting about Trichocereus andalgalensis in our Trichocereus Facebook Group. It´s not a very common type, but chances are some of our older members might still have some from the time when Friedrich Ritter sold seeds of this plant as FR 428.
This b/w pic shows Trichocereus Andalgalensis var. auricolor. It is probably the same type as shown in the color pics below.
So here´s another video from the 2020 season, while I …
