Trichocereus riomizquensis RITTER (Echinopsis)

Trichocereus riomizquensis RITTER (Echinopsis)

Trichocereus riomizquensis is a Bolivian Trichocereus species that is closely related to Trichocereus bridgesii. I count it as a close relative and potential regional form of Trichocereus bridgesii, which is only endemic to one site in Bolivia near the Rio Mizque.
The species was discovered and described by the German cactus field botanist Friedrich Ritter, who gave Chuyllas as the type locality and described it growing on steep slopes in the province Campero.

His Field Number was FR 856. Friedrich Ritter was one of the leading Cactus experts of his time and successfully ran a seed shop, in which he sold this species as seed to people all over the world. Trichocereus riomizquensis was also visited during the Sacred Succulents Fieldtrips and they found a couple of different types growing around that area.

In Ritter´s book, he published a photo of this species. Unfortunately this photo is not very good and it is one of the species that are rare in cultivation. Almost all labels on plants grown from Ritter´s seeds are lost, but the plant is definitely available. On the market, it sometimes shows up labeled as Trichocereus bridgesii, or probably also labeled as Trichocereus PC. Please note that there is a wide variety of plants from this site and the range is very big, ranging from spiny to completely spineless plants.

Ben Kamm published some photos of a Herbarium specimen that was very close to Trichocereus bridgesii as well.

Where to buy seeds and plants of Trichocereus riomizquensis?:

Though Trichocereus riomizquensis is common in cactus collection in the USA, it is usually mislabeled. Sacred Succulents were giving away seeds after their Field Trips and some plants might have gotten into the hands of collectors. They are also selling live plants grown from their collected seeds sometimes.

Description of Trichocereus riomizquensis:

This is partial description of Friedrich Ritter´s original description, including remarks on how to keep it apart from T. scopulicola.

Trichocereus riomizquensis is 6-8 centimeters thick (while Trichocereus scopulicola is 8-10 centimeters thick), it has 5-6 ribs, (T. scopulicola: 4-6), its flanks are 2 centimeters wide (Scopulicola 3-4 cm wide flanks), the flanks are less rounded than the ones on Tr. scopulicola. It has rounded areoles (while the ones on T. scopulicola are usually oval). The areoles have a very visible fluff with a diameter of 2-3 mm. The 1-5 spines are honey-colored and between 1-3 mm long. Sometimes they are even missing.
The flower of Trichocereus riomizquensis is 20 centimeters long (while the flowers of T. scopulicola are 16-20) and covered with dark brown/white wool with large scales. The fruit looks knobby.

Type locality: Chuyllas near the Rio Mizque, on very steep rock walls in the province Campero, Bolivia. Discovered from Ritter in 1958 – FR 856.

Trichocereus riomizquensis is one of the most interesting species from the Sacred Succulents Field Trips because of its incredible range. Some plants look like the Trichocereus bridgesii-type plants with long spines from the Field Trips and some other ones look like the short spine versions that Friedrich Ritter´s description was about.

If you take a close look at the whole appearance of this plant, you can see that it has a similar areole shape to the areoles on the well known Trichocereus PC clone, also known as predominant cultivar or predominate cultivar.  The flower and the overall appearance are so similar that everything else would be extremely surprising. Despite the fact that there are some very spiny plants at this site, there are some other which get extremely close to Ritter´s original photo. Though this will probably never be proven, there´s definitely reasonable doubt that this PC clone is actually a Trichocereus pachanoi.

There is a lot variation within the populations the original site near the Rio Mizque. This population is one of the most interesting Trichocereus populations out there and DNA testing should absolutely be made to look into its relationship to Trichocereus bridgesii.

Where to buy seeds or cuttings of Trichocereus riomizquensis:

Well, Ben and Sacred Succulents would be my starting point if I were in the USA. They don´t ship plants internationally, but if you have the luck to be in the country you might be able to get some cuttings. Apart from this, I do not know any sources for this species. Most of Ritter´s old plants have lost their labels meanwhile, which makes getting one even harden. I am sure that some of them show up on online market places labeled as Trichocereus bridgesii every now and then.

Trichocereus sp. ‘Isla del Sol’ (Echinopsis)

This population from the Bolivian island ‘Isla Del Sol’ belongs into the distant complex of Trichocereus bridgesii / Echinopsis lageniformis. However, it is currently discussed whether or not this plant is actually a different species and DNA testing is required to look into its status.  Sacred Succulents visited this population during their Field Trips and made some amazing photos. I also have some sick photos of it in my first book.

 

BK08601.1 Trichocereus Isla del Sol, Bolivia

Now, this is one of the most interesting Trichocereus species that were visited during the Sacred Succulents Field Trips! All the photos shown here are from Ben Kamm & Sacredsucculents.com! This was from the 2008 Field Trip and it is very similar to an intermediate between Trichocereus bridgesii and something from the Trichocereus cuzcoensis complex. Trichocereus cuzcoensis is mostly known for the plants in Cusco that were used to write the original description, but there are similar plants and relatives of Trichocereus cuzcoensis that can be found in other Peruvian states.

It also reminds me a little bit of Trichocereus knuthianus, which also belongs to the Cuzcoensis complex and has similar, massive areoles. Those plants are definitely very old…how they evolved exactly is not known.
Sacred Succulents gave away seed of this amazing species in 2008, but I do not know of anyone who raised some of them so far. If you happen to own this type, please let me know because it´s on my most-wanted list and I urgently need more pics of seed grown plants. The Isla Del Sol is an area that can be found in the southern part of the Lake Titicaca in Bolivia. It´s a wonderful area that is filled with ancient ruins and that screams “History”. I do not know if those plants were intentionally planted there or if they just evolved, but it´s definitely one of the coolest Trichocereus species out there.

The history of the PC Trichocereus clone – Predominant cultivar

The history of the PC Trichocereus clone – Predominant cultivar

I wanted to clarify some things about the PC Trichocereus clone. What it is, where it probably is from and what it isnt. The name is probably the most overused name in the history of Trichocereus culture. I personally hate it and spent days discussing the whole situation with friends or interested people in the Trichocereus Facebook group. If you hear the word PC in a Trichocereus group, JUST RUN. Log off, go outside and be in your garden. Still, if you actually wonder what those guys are actually talking about, I am happy to shed some light on this issue. Please keep in mind that I hate to use the name of this cultivar, strain or whatever you might want to call it and I will only mention this one time and one time only.

What does PC stands for? It originally means PREDOMINATE CULTIVAR. However, PREDOMINANT CULTIVAR would probably be more appropriate.

Now what is it really and is this all BS?

It is a clone, but there also are other plants grown from seeds that are probably coming from the same site this clone is coming from too. In California and parts of the USA, this clone is really common around parks, schools or gardens. It is very similar to most other San pedros, but it originally comes from Bolivia. This plant was originally collected by Friedrich Ritter and described as Trichocereus riomizquensis.

Trichocereus Riomizquensis 335This is the original photo from Ritter´s book. Do you see the white hairs on the flower and the way the areoles look? Well, keep in mind. You will need it later. Ritters official collection name of this plant was Trichocereus riomizquensis FR856 and they originally comes from Chyllas.

The original site is the Rio Mizque and we and my friends from Sacred Succulents visited the original site a couple of times.  It is extremely similar to Trichocereus pachanoi, but differs in substantial points like the hairs on the flowers and the overall rib structure. Though it is common belief that the San Pedro cactus aka Trichocereus pachanoi grows in Bolivia, all the San Pedro related plants we ever came across IN THE WILD either belonged to Trichocereus bridgesii or Trichocereus scopulicola. That also applies to the regional type from the Rio Mizque. I have all kinds of photos of those plants on the pages about Trichocereus riomizquensis and I don´t want to repeat this information here again.
This is a long-spined version of this but there also are a lot of short-spined ones on that site. I seen them. Just like this PC, they have 6-7 ribs, those weird areoles and golden spines without swollen spine bases. Overall, they are just a short-spined version of Trichocereus bridgesii.

Let me just say that one thing that the Bolivian Trichocereus species have in common is their drought resistance. They literally live in a hot desert and are a lot more resistant to drought than Trichocereus pachanoi or some of the other Peruvian San Pedros. And that´s where I want to draw the line directly to this Californian clone. Clones & cultivars are not humbug or bullshit….cultivars exist in EVERY field of commercial cultivation and everyone who tells you different is a fool. One such cultivar is actually this Tr. riomizquensis that was originally described by Friedrich Ritter. Is is extremely drought resistant and manages to thrive in the Californian climate. That´s why this plant is literally everywhere there. We tested it numerous times…almost none of those Californian plants were able to mate with each other…simply because they were genetically identical and cuttings of each other. I seen whole nurseries filled up with them because they are so damn easy to grow. They just cut them in small pieces and stick them into the ground. And after five years, they sell it for 30-100 bucks. All those plants share the same flower characteristics and are closer to Trichocereus bridgesii than they are to Trichocereus pachanoi. They are covered with white hairs, which is absolutely typical for Trichocereus bridgesii. I know a Bolivian Trichocereus species when I see one…and this PC is one without a doubt.

The flowers of the PC:

PC Flower_7

Do you see all those white hairs? Good, because it´s important to differentiate between certain Trichocereus species. Trichocereus pachanoi tends to have black or brown hairs, while this PC has white hairs. And that´s typical for the Bolivian San Pedro strains.

pcPachBudDSC_0462Those two photos are from Misplant.net! Check out their seeds because they are amazing.
Well, just compare the photos and see for yourself. The top photo is the flower bud of this PC Trichocereus and the lower one is a bud on a Trichocereus scopulicola. They are at different stages in their development, but I am sure you see the similarity in the important parts. And the same applies to the flower on Trichocereus bridgesii, which is another Bolivian Trichocereus.

Scop from Misplant.net

Alright, now that we have this out of the way let me just say that the whole internet started having shitty discussions about the PC and what not. Most of the times, those guys just pick out one of the charasteristics of those plants and call  everything that resembles this Californian strain a PC…which is a really bad generalization. Imagine you were a botanist and field explorer that collected seeds in Bolivia. Now you find a cool regionality that produced a whole lot of seeds. Friedrich Ritter was this guy and collected so many seeds that he could populate the whole world with them…which he probably did. He sold his seeds through his Winter Samenlisten (which were written in three languages) and shipped them everywhere. Like literally. People grew them, raised those plants and planted them in their gardens. Some in California, some in Australia and some in other places of the world. That PC clone from California and the rest of the USA is probably just one cutting that was grown from those seeds. All the plants cloned from this one plant are genetically identical. But that doesn´t mean there can´t be more plants grown from the same seeds…which in fact are genetically diverse. You know, this whole site at the Rio Mizque is pretty big and as far as I know, Ritter collected loads of fruits. These days, most labels are lost but what´s left are the plants. And they are usually slapped with a short PC comment in the Facebook groups, though that is only a tiny piece of the puzzle.

And just to make sure this posting here is not misinterpreted. Are all the plants called PC the same? NO, absolutely not. Many people throw this word around and have absolutely no idea what they are talking about. Just one example. Here is a Bolivian San Pedro. As those are also related to Trichocereus bridgesii, they have a similar rib structure. Imagine them with long golden spines and you are good to go.

Trichocereus riomizquensis

Trichocereus aff. pachanoi in Boliva

Well, okay. I want to come to and end but it´s important to make a very good point. YES, there are many San Pedros that are extremely similar to this clone. Not all of them are the same and I am sure there´s a fair amount that has absolutely nothing to do with this PC. But there IS a common clone in the USA (apart from the many other cultivars that are there, such as the three or four types of cereus monstrosa or all the other mutants that are currently flooding ebay. Nurseries are in the money business and they will replicate everything they can sell. And those Bolivian Trichos (and I count that PC in as well) are TAH (Tough as hell). You literally stick them in the ground and they grow. And that played a part in the fact that this PC Trichocereus strain is so common in some parts of the USA.

Alright, I want to sum this up. Everyone is a bit in the right here. The way this plant is discussed recently is out of control. And some people tend to forget that there is a huge number of plants that are really similar to this PC…and they are coming from the habitats. In Peru, there are similar plants and I just posted the examples that you can find in Bolivia as well. But that doesn´t mean that those plants were just invented by cookoo internet theoreticians. They were collected, sold and commercially cultivated. This plant does probably NOT come from Backeberg, which is another theory that was discussed heavily.

Trichocereus bridgesii (Echinopsis lageniformis)

Trichocereus bridgesii (Echinopsis lageniformis)

Trichocereus bridgesii (SD.) Britton & Rose – The Cactaceae, now called Echinopsis lageniformis because the name Echinopsis bridgesii was already taken.

C.F. Förster – H.Friedrich & GD Rowley 1974

CITES: Appendix II.

Origin of Trichocereus bridgesii:

Trichocereus bridgesii, also known as Echinopsis lageniformis, grows throughout Bolivia (LA PAZ, Chochabamba, Chuquisaca, Santa Cruz, Tarija. There are many close relatives, such as Trichocereus riomizquensis, Trichocereus crassicostatus, Trichocereus scopulicola and the populations from Isla Del Sol.

Synonyms of T. bridgesii:

Cereus lageniformis, cereus bridgesii, trichocereus crassicostatus, Cereus bridgesii var. longispinus, Cereus bridgesii brevispinus, Cereus lasiacanthus, Trichocereus boliviensis, Trichocereus riomizquensis (some of them),  and many more.

Some of the Varieties or commercial types on the market:

KK919 Trichocereus bridgesii, KK920 Trichocereus bridgesii, Trichocereus bridgesii Cristata, TBM type A, TBM type B, Lumberjack, Eileen, Jeans, Psycho0, TBM,  Penis Plant, Penis Cactus, Frauenglück or Frauenglueck, Trichocereus bridgesii var. Inermis, Eileen,and many more

Trichocereus bridgesii has been renamed to Echinopsis lageniformis by Friedrich and Rowley during their 1974 merger of the genus Echinopsis. The name Echinopsis bridgesii was already taken by a clumping Echinopsis species from Bolivia, which is a totally different plant and should not be confused with Trichocereus bridgesii.

Trichocereus bridgesii is also called the Bolivian Torch or Achuma and is a very fast growing columnar cactus from the high deserts of Bolivia. It its extremely drought tolerant and withstands colder temperatures than some other Trichocereus species. If you are new to cacti but want to grow one of the San Pedro type cacti, Trichocereus bridgesii is a perfect plant for you.

Description of T.bridgesii

Healthy plants of Echinopsis lageniformis  Trichocereus bridgesii have a light green epidermis and between four to eight ribs. The spines can range in coloration from honey-colored to brown, and are located at the nodes in groups of up to four.

It grows similar to a tree and reaches a size of up to 5 meters. The Species is not as glaucous as Trichocereus peruvianus and Trichocereus pachanoi and has a light green epidermis.

Trichocereus bridgesii reaches up to 15 centimeters in diameter and large specimens are often confused with Trichocereus peruvianus. The fact that very thick specimens can look a lot like Trichocereus peruvianus is a reason that there are many misidentified specimens on the market. Some sellers even label them “SAN PEDRO”, “PERUVIAN TORCH” or simply Trichocereus peruvianus / Trichocereus pachanoi, because they usually are more expensive as Trichocereus bridgesii.

It has 4-8 Ribs and the Areoles are about 2 centimeters distanced of each other. Four-ribbed plants are sometimes called “Trichocereus of the four Winds”, though it´s actually a lot more common for this species to grow or lose a rib than you would think. Besides, that four winds stuff is oftenly used as a marketing gimmick, though the plants grow and lose ribs all the time.
A Trichocereus that grows a rib looks very much like it would put out some monstrose growth, but on the long term you see that it´s just ribs.

But yeah, the larger they get the more ribs they can have. Trichocereus bridgesii has very broad furrows. The plant can reach up to 3-5 meters.

Spines of Echinopsis lageniformis / T.bridgesii:

4-6 needle-like, yellow Spines. Some of them are very uneven and vary greatly in length and appearance. Some large plants even lose their spines completely. This is something that we encountered a couple of times on larger plants and spineless Bridgesii´s look very much large hybrids between Trichocereus peruvianus and Trichocereus bridgesii.

Flower of Tr.bridgesii :

The flowers of Trichocereus bridgesii are white and up to 20 centimeters long and 10 centimeters in diameter. Trichocereus bridgesii is a night flowering species and its fruits are usually up to 5 centimeters long. It had white petals and small scales and hairs on the rest of the flower.

Type locality:

Bolivia, La Paz

Trichocereus bridgesii as Grafting Stock:

Trichocereus bridgesii is an excellent grafting stock and is used extensively for that. Though it´s a great stock, it´s not as accepting as Trichocereus spachianus or a cereus. Nonetheless, it´s a strong and vigorously growing stock that will produce large scions very fast.

Regional forms of T. bridgesii:

The fact that most regional forms look very similar makes it very hard to differentiate between them. There are many known clones available, but Trichocereus bridgesii isnt just as variable as the Peruvian species.

The monstrose form of Echinopsis lageniformis/Trichocereus bridgesii is called PENIS PLANT or TBM, sometimes also called Trichocereus bridgesii Inermis. Contrary to the typical columnar growth habit of the species, the TBM cultivar displays short stem segments that branch forming a small bush. The upper part of each stem section is smooth and spineless, resembling a certain male body part. The lower part shows a tendency to form ribs and is spiny. The plant is light green in color.

Cultivation of Trichocereus bridgesii

This species is one of the strongest growers in the genus Trichocereus or Echinopsis. It´s VERY drought resistant and less problematic than other Trichos. Especially if you grow them from seed, because no matter what else you grow, they will be the ones to survive the longest if you suddenly “forget” to water them for a month or so. The come from Bolivia and live off very little water but also manage to compensate strong rainfalls and are rarely affected by fungal infections or mold. It´s a very thankful plant to grow, especially when you have the luck to plant them outside.

So, cultivation is pretty easy. Don´t water them when it´s cold. It´s the same treatment that you would give any other Trichocereus. Only water them during the hot growth season in summer. If they are in full growth and the temperatures are high, they like to be watered on a weekly basis, but it depends on how fast the soil dries up.

Hold back the humus

They don´t like soils that contains too much humus and i´d recommend to grow them in a purely mineral soil mix, with pumice, coarse river sand and maybe a very little bit of standard cactus soil to make sure that they are able to take in the nutrients. Generally speaking, Trichocereus bridgesii is the  archetype of a cactus that thrives on poor soils. I would not recommend to put them in full sun for the whole day but they can take much more sun that other Trichos that come from more tropical climates.

Winter treatment & frost tolerance:

Trichocereus bridgesii is able to tolerate mild frost. The minimum temperature should now go below -5° Celsius though.  Trichocereus bridgesii usually has no problems to compensate light night frosts but the average minimum temperature should not be lower than 10° Celsius! That is around 50° Fahrenheit. One important factor in frost resistance is the humidity of a soil! Plants should be totally dry in winter to make it easier for them to deal with frost. That´s why growers in Europe and other countries with strong frost have to take em inside in winter. The moisture is more dangerous than the cold, though there is a temperature that will kill all cacti no matter how dry they are. Cacti require a bright and well ventilated space with a temperature around 10° Celsius. Not only ensure it that the plants soil system does not rot, it also promotes flowering!

Cultivation from seed:

Trichocereus bridgesii is very easy to grow from seed. The seeds remain their viability for 5-10 years and some even longer. The best germination rate can be expected within the first year though. The seeds require light to germinate and you only sprinkle them on top of the soil. As a germination medium, I would recommend a mix between sowing soil and coarse sharp sand. This reduces your chance of contamination and/or Algae/Moss production.

Moss and algae problems on Trichocereus

Moss and Algae are a real problem for cactus growers because they overgrow your seedlings and usually kill them. If you see green crap on your soil, that is exactly what I am talking about. The seeds only need very little water to germinate, so do not overwater them in the beginning. You can always add more water but you can never take back a bad overwatering because it usually washes the seeds away or will lead to rotten seeds and soil.

Germination temperature for E.lageniformis

Germination temperature for Trichocereus bridgesii or Echinopsis lageniformis is around 25°-30° Celsius. But be careful because small seedlings die very easily because of too much heat. Especially if you germinate in closed containers, temps can get quite high in there. The time needed for them to germinate is between 2-6 weeks. If nothing has germinated after that, it´s probably because a.) there wasn’t enough water to kick start the germination. In this case just add more water and wait some more. b.) the temperatures were not high enough. In this case, just increase the temps and continue to germinate. Or C.) The seed is dead.

Bad quality Trichocereus seeds

There are a couple black sheep in seed business who sell seed that´s between 10-20 years old and the viability is horrible. So if you did everything right and nothing germinated, it´s the seed. Seed quality on the market varies greatly and you never know what batch you will end up with. So if you had a batch batch, I´d recommend you to contact the seller and ask him about it. Stay friendly and polite and they will replace it because they are aware of the great differences in seed quality.

Propagation: 

Trichocereus bridgesii can be grown from seed pretty easily. But you can also take cuttings and re-root them. This way, you can multiply your plants dramatically and if you are trying to get a lot of plants, you can also try areole grafting. Trichocereus bridgesii is pretty tough and you can basically stick it in a dry medium like sand and it will probably grow. Just make sure to let the cuts dry out and give the wound enough fresh air until everything is calloused. I use bird sand for that purpose, which is the mineral soil mix that you get in pet stores for the birds to take their dump in. It contains anise and some other minerals that just prevent mold and infections and it is perfect for rooting plants in it.

USDA Zones Trichocereus bridgesii: 

10a, 10B and 11

Purposes: 

Can be used as grafting stock or just because its´an amazing cactus. Besides, Trichocereus bridgesii is used as natural fence to keep away animals and people.

Trichocereus hybrids (Echinopsis)

Trichocereus hybrids (Echinopsis)

There are all kinds of Trichocereus hybrids out there and I am happy to show you a couple of the resulting crosses on this page. I will try to update this page as often as I can, to show you what others grew from a certain cross.

Now let me add a little bit of background info to give you an understanding how this breeding works in case you are completely new to this. Almost all Trichocereus species are self-sterile. That means that you need pollen from another plant to produce seed. The pollen donor needs to be genetically different from the receiver. Because of that, it´s not possible to cross two different cuttings from the same mother plant. If you list the parents of a cross, it looks something like this:
Trichocereus peruvianus x Trichocereus bridgesii
That simply means that the Peruvianus is the mother plant, while Trichocereus bridgesii is the Father. In most cases, the resulting offspring comes closer to the mother than to the father. However, there are a lot of exceptions to this and sometimes, the genes of the father are simply more dominant.
You can cross a whole lot of Trichos with each other and most of the crosses will work, if you did it right. But there are some crosses that just genetically don´t match. For example, the seedlings produced by that cross end up being variegated/albinos or simply die. That´s actually very common and can happen all the time. It happens the most when crossing plants like Hildewintera hybrids. And that´s probably because there werent many plants in the gene pool to begin with.

Most Trichocereus species have a white flower and apart from the extremely rare Trichocereus tulhuayacensis, all San Pedros are flowering white. Because of that, this community is trying to breed some San Pedros with colored flowers. There already are a handful of hybrids involving Echinopsis pachanoi with colored flowers. One such Trichocereus hybrid is called SAARWELLEN and the other one is AMUN-RE. But both Trichocereus hybrids are extremely rare.

Now, have a look at some of the photos of Trichocereus hybrids

Trichocereus bridgesii / Echinopsis lageniformis in Bolivia

 Echinopsis lageniformis / Trichocereus bridgesii in Bolivia

Echinopsis lageniformis or Trichocereus bridgesii is probably THE dominant Trichocereus species in Bolivia. Yes, there are others but this species pretty much reflects the Bolivian counterpart to its Peruvian sister species like Trichocereus pachanoi and Trichocereus peruvianus. The populations usually get up to 4-5 meters tall and form large groups. This plant is probably one of the most drought resistant Trichocereus species, which it manages to survive even the extreme temperatures in the Bolivian desert.

Read the full database entry on Trichoereus bridgesii / Echinopsis lageniformis here: https://trichocereus.net/trichocereus-bridgesii-echinopsis-lageniformis

The Californian Nursery Sacredsucculents.com visited some regional populations of Trichocereus bridgesii / Echinopsis lageniformis in their Field Trips and I am extremely glad to have them here on the website. All photos are from Ben Kamm.

BK08603.3 Trichocereus bridgesii & BK08603.2 Prosopis alba, Huachjilla

This plant is very similar to the ones labeled Trichocereus aff. pachanoi. You can definitely see why so many people say that Trichocereus pachanoi grows in Bolivia too. They are extremely similar and it takes a lot of time and effort to differentiate them. The plant grows beside Prosopis Alba!

BK08608.2 Trichocereus bridgesii, mutant Achuma, NE La Paz, Bolivia

Another plant from the Sacred Succulents Field Trip 2008. A mutated version of an Achuma cactus that is just mindblowing. This is the type of thing that you can only encounter in nature. Those amazing walls of cactus are probably some of the most impressive sights that you can come across.

BK08608.3 Trichocereus bridgesii,NE La Paz, Bolivia

 

It comes from the same site as the BK08608.2 Trichocereus bridgesii / Echinopsis lageniformis, but from a different Plant! The BK08 means that it was visited by Ben Kamm in 2008. The later numbers are either labeled BK09 or BK10. There also were some plants that were visited during the 2014 Field Trip, which were labeled BK14. Those plants are dark green and very similar to what is understood as San Pedro. The flowers are covered with white hairs, which is a great way to keep it apart from most of the Peruvian San Pedros.

Echinopsis pachanoi in Bolivia?

Echinopsis pachanoi in Bolivia?

There are many people or books referring to populations of the Echinopsis pachanoi in Bolivia. But much unlike popular belief, most of those plants are actually spineless varieties of Trichocereus bridgesii. Though both species can be very similar under certain conditions, you definitely see the difference on flowering plants. Echinopsis pachanoi usually has brown or black hairs on the flowers, while the hairs on the Bolivian species are often white.

Here are some of the Bolivian Echinopsis pachanoi populations that were visited during Sacred Succulents´Field Trips. Most of the plants are labeled Trichocereus aff. pachanoi, what stands for „affinity to Trichocereus pachanoi“. That means that those plants look similar to Trichocereus pachanoi, while they probably are more closely related to Trichocereus bridgesii. Don´t forget that Trichocereus pachanoi is widely cultivated in every South American country today. It´s just that the Bolivian version of Echinopsis pachanoi is Trichocereus bridgesii, which is also called Achuma or Cactus of the Four Winds. The latter has become a catchy marketing phrase for everything that has four ribs, but that has more to do with marketing than ancient history. Nonetheless, this phrase has been used for a four-ribbed Bridgesii type. With that said, many plants can temporarily have four ribs, but usually grow some later on.

Here I will show some photos from the Sacred Succulents Field Trips from Bolivia. All those pics are from  Ben Kamm and Sacredsucculents.com. Please support them to make more Field Trips like those possible!

 BK10512.11 Trichocereus aff. pachanoi, near Cuchucunata,  Cochabamba, Bolivia 

 BK10512.11 Trichocereus aff. pachanoi, near Cuchucunata,  Cochabamba, Bolivia Those plants are relatively spineless, but look pretty typical for Bolivian plants between Trichocereus pachanoi and Trichocereus bridgesii. In my eyes, those are just spineless or relatively spineless forms of Trichocereus bridgesii but you would need to take a look at the flowers to verify. There certainly are some cultivated Pachanois in Bolivia, but they are grown as natural fencing or garden plants are did not evolve over time. Most populations of Echinopsis pachanoi in Bolivia are actually Trichocereus bridgesii.

Trichocereus aff. pachanoi, Arani, Cochabamba, Bolivia 

On this one, you can see the obvious relationship to Trichocereus bridgesii. I originally wrote that it might be related to Trichocereus scopulicola, but it could as well but just another type of Trichocereus bridgesii. But the labeling with aff. pachanoi fits pretty good, though those are all closer related to Trichocereus bridgesii than they are to Trichocereus pachanoi.

BK10508.5 T. aff. pachanoi, Tiatako, Cochabamba, Bolivia 

Another version of Echinopsis pachanoi in Bolivia, but which is actually closer to Echinopsis lageniformis, aka Trichocereus bridgesii. This one is the most interesting, because it might actually be a relative of Trichocereus scopulicola. But I would need to take a closer look at the rest of the plants. On the second pic, the ribs look very much like the ribs on a Trichocereus scopulicola.

BK10508.7 Trichocereus riomizquensis, Totora , Cochabamba, Bolivia

BK10508.7 Trichocereus riomizquensis, Totora , Cochabamba, Bolivia 

Trichocereus riomizquensis BK10508.7 is a very cool Plant! that is obviously related to Trichocereus bridgesii.

Trichocereus riomizquensis is probably partially synonymous with Trichocereus bridgesii or belongs to Trichocereus bridgesii in a wider sense. The latter is not very surprising because both are from Bolivia and grow very close to each other.

Ritter gave CHYLLAS near the Rio Mizque in the province Campero as the type locality of Trichocereus riomizquensus, growing on rocky slopes.

Ritter assigned the FR/Winter seed code (after the name of his sister, who ran his seed business) FR856. After all these years, there are only very few plants of Ritter´s FR856 left which still have their original label intact and if thereanybody out there who grows a plant labeled Trichocereus riomizquensis FR856, please let me know and I will add them to the database! There were also seeds given away in the Sacred Succulents Field Trips and I´d love to see photos of the offspring as well.

If you are interested in Trichocereus riomizquensis, it can´t get any better than seeing the species in field expert Martin Cardenas´garden in Chochabamba. This plant is very unique, but also shows a close connection to Trichocereus bridgesii. I am sure if I was to take a look at the flowers now, I would see a flower that is extremely close to the flower of Trichocereus bridgesii. Buds, flowers and fruit bear white hairs, which can also be see on the notorious PC clone in the United States (which we suspect might be grown from Ritter´s Trichocereus riomizquensis seeds).

SS02 (Trichocereus bridgesii)

SS02 (Trichocereus bridgesii) 

SS02 stands for a certain clone brought into cultivation by Ben Kamm & his nursery Sacred Succulents. It is a relatively short-spined Trichocereus bridgesii that is known to produce some mind-boggling offspring. Most of the hybrids produced with this plants do not look like a standard Bridgesii and due to the fact that Sacred Succulents has been offering them for years, there is a huge number of different SS02 Hybrids available.

Here is an excerpt of Sacred Succulent´s description of their SS02:

Dense candelabra stands to 16´tall. Blue/green frosted stems up to 5″ in diameter with 5 – 7 ribs. Each areole bears 2 – 4 central spines up to 1.5″ long. White nocturnal flowers. The new growth on old stemps is often spineless. A distinct form of Trichocereus bridgesii. Cold hardy to 25° Fahrenheit. 

The Pictures of the SS02 clone were provided from Nitrogen!

And here are some hybrids that were created with the SS02 clone! If you want to some cuttings or seeds of the SS02, check out the Sacred Succulents website and ask for their seed list. There will be more SS02 hybrids to be seen in my upcoming book SAN PEDRO HYBRIDS.
