Trichocereus puquiensis / Echinopsis puquiensis

Trichocereus puquiensis Echinopsis puquiensis

The species Trichocereus puquiensis, also known as Echinopsis puquiensis, was described by Rauh & Backeberg as Trichocereus puquiensis Rauh et Backeberg nov. spec.. The description was originally published in DESCR. CACT. NOV. vol. 20 in 1956.

Depending on who you ask, there is a constant debate about whether or not this species is a “good name”. Anderson included it in his Cactus Lexicon as Echinopsis peruvianus ssp. puquiensis. Personally, I think that this plant is closer to Trichocereus pachanoi than it is to Trichocereus peruvianus. On the other hand, I also think that Tr. pachanoi and Tr. peruvianus are probably a very large and variable species with many intermediates between the two and I would not mind to throw Tr. puquiensis in there as well. The rib structure and areole shape of Tr. puquiensis is similar to the one on Tr. pachanoi. The big difference is that Tr. puquiensis has 8 – 11 ribs and a strong groove above the aroles. Please note that there are many different types from the Puquio region, what is the cause for the large number of different plants that go by this name.

Trichocereus Puquiensis gets up to 4 meters tall, but most plants are around 2 meters. It pups from the base and grows as columnar shoots, growing upwards. Tr. puquiensis has no cuzcoensis-ribs but a very similar spination. Think of it as a 8 – 11 ribbed Pachanoi with long cuzco spines that lack the typical cuzcoensis swollen spine bases. This is another giveaway that helps you to ID it.
The color of the epidermis is blue/green. It reaches a maximum diameter of 10-20 centimeters with ribs that are between 1-2 centimeters high, the areoles are 1-2 centimeter in diameter and felted, similar to the areoles on Trichocereus cuzcoensis.
Trichocereus puquiensis has 10-12 radial spines that are up to 2,5 centimeters long. The new spine growth of the radial spines is brown. It also has 1-2 long middle spines, of which one or two are pointing upwards. Those middle spines are 8-12 centimeters long. New spine growth is brown and old spine growth is gray, very similar to the one on Tr. cuzcoensis. You see it´s not a typical Pachanoi but a intermediate that involves traits of various species. Please note that there are some plants in the Puquio habitat that are in fact cuzcoensis related, and the Trichocereus puquiensis from Karel Knize is actually one of them.

Flowers: The flowers are 15-22 centimeters large and white. A typical San Pedro flower. The tube is up to 2.5 centimeters thick and hairy.

Fruit: Unkown. Probably similar to Pachanoi or cuzcoensis fruits.

Habitat: Puquio, Department Ayacucho and it only occurs there. It grows in neighborhood of Erdisia Quadringularis. Rauh assigned the collection number K119.

This is Rauh´s original, latin description, which slightly differs from mine.

Planta 3-4 m alta, a basi ramosa; caules columniformes glauci, 8-10 costati usque 15 cm crassi: costae angustae, ca- 1,5 cm altae; areolae 1cm in dia. lutei-brunnescenti-tomentosae, aculeis marginalibus ca. 10 usque 2cm longis, in calulibus hornis brunneis;aculei centrales plerumque 2, quorum superior oblique erectus vel transverse patents, usque 10 cm longus, basalis oblique deflexus 5-8 cm longus, in caule hornio badius, senectute canus; flores usque 15 cm longi, tubus floralis etiam in statu ante efflorationem rectus, usque 2cm crassus, squamis bractaeneis dense obtectus, quarum pars libera late trigona, in apicem obscurum excurrens, in axillis earum pili lanei brunneo-atri; phylla perigonii exteriora subtus basi rubiginosa, supra virescentia, interiora alba, filamenta, stylus et stigmata virescentia, radii stigmatis 19, ca. 5mm longi, cavum ovarii ferequadrangulare, 0,7cm in dia., nectarium 1,5 cm. longum, angustissimum, stylo crasso fere omnino expletum; fructus ignoti.

Friedrich Ritter sold Seed labeled as FR 155b. Ritter said that the Species would rather resemble Trichocereus pachanoi than Trichocereus cuzcoensis and I tend to agree. The species is limited to the pacific part of the Andes, while Tr. Cuzcoensis grows on the Atlantic Part. After years of investigating I finally think that Ritter was probably right, what means that Tr. puquiensis is more on the Pachanoi end of the spectrum. He knew the South American cacti better than everyone else, but during that time, many regional varieties were described as species and most of them did not age well and ended up being merged into Tr. peruvianus or Tr. pachanoi. I thought about this species a lot, and I guess there are plants that have traits of more than one species.

Karel Knize sold seeds & plants under that name too. Knize´s Trichocereus puquiensis is extremely close to Trichocereus cuzcoensis, but has a couple more ribs than a standard cuzcoensis.  Apart from that, the ribs are clearly Pachanoi ribs. I´ve seen plants with five ribs and some with ten.

Every time you come across a plant with more ribs than usual, Trichocereus puquiensis should be a considered option. It also does not have rounded spine basis, what clearly differentiates it from Trichocereus cuzcoensis. Knize´s version is becoming more and more common because Karel Knize sold large amounts of seed and plants in the past years.

Cultivation of Trichocereus puquiensis:

There is very few information about frost tolerance of Trichocereus puquiensis available. It should be grown like a standard Trichocereus pachanoi or peruvianus, because it´s general growth type is similar to that. It can tolerate frost but temperatures should not be lower than -5° to -10° celsius. Plants should be kept totally dry over winter.

Buy seeds or plants of Trichocereus puqiensis: 

You can buy seeds of Trichocereus puquiensis in my shop.

In the USA, I know of one supplier that grows the genuine Tr. puquiensis from Rauh & Backeberg´s description.! In Australia you can get live cuttings from the SAB shop.

HB01 (Trichocereus pachanoi?)

Trichocereus HB01 is a clone that originally comes from the Australian Shop HERBALISTICS. The plant was sourced from a garden in the Australian city Gatton in Queensland. The clone is usually short spined, but can get more spiny at a larger size.

It looks like a Trichocereus pachanoi with an very high rib count, or one of Friedrich Ritter´s Trichocereus puquiensis. It is very similar to Ritter´s old description. It tends to have a higher number of ribs than standard T.pachanoi or T.peruvianus. Tr. puquiensis was described with having 8 – 10 ribs and the pics that I got from the SAB member LHB2444 definitely fit the description. But yeah, not sure since this clone has very little background info attached to it. I´ve seen some cuttings of this clone develop some kind of skin discoloration and it´s possible there´s either a genetic or pathological reason for this. We´ll stay on the case to find out more. But yeah, it belongs to Trichocereus pachanoi and I suspect it to be Trichocereus puquiensis.

The photos below (Zed240) show a plant that was labeled HB01 but looks a little bit different and has substantially longer spines as the one in the first two pics. That being said, there is a great variability within all the Trichocereus species, so I would not be surprised if that difference in spine length is caused by environmental factors. There also are 5 – 6 ribbed plants from Puquio and this second plant might be one of them. But no matter if the HB01 clone is actually a Trichocereus puquiensis or a Trichocereus peruvianus, it definitely as an amazing plant that will look awesome in your collection. You can find the description and photos of Tr. puquiensis here!

Crowdfunding Campaign TRICHOCEREUS book VOLUME 1

Crowdfunding Campaign TRICHOCEREUS book VOLUME 1 2

This is the crowdfunding campaign post for our first Trichocereus book TRICHOCEREUS VOLUME 1: THE SAN PEDRO GROUP. This book has since then been published and can be found in our shop. All links below are no longer valid.

Crowdfunding Campaign TRICHOCEREUS book VOLUME 1

Example photo. Original not identical

Hi guys, I just wanted to take the time to let you all know about the status of my crowd funding campaign for the printing costs of my book TRICHOCEREUS VOLUME 1: THE SAN PEDRO GROUP. Until 2016, this book was available exclusively through my Indiegogo campaign here:

The campaign is now closed, but it is now up for sale in our shop here:

I´ve been working on this book for a few years now and it´s finally getting close to a release date. It´ll have more than 300 all-color pages and will contain hundreds of color pics showing plants from the San Pedro Group in the habitat, botanic gardens and collections worldwide. There were dozens of well known people helping me with photos for this book and I am extremely proud that I was given the chance to write it! I´ll make sure it´ll be a high quality book that will look awesome on your shelf! There will be descriptions, photos and cultivation advice as well as a detailed guide on how to germinate difficult seed. The book takes a close look at flowers, fruits and old names that are no longer valid. This book contains a whole lot of different species and commercial varieties like Trichocereus pachanoi, Trichocereus peruvianus, Trichocereus bridgesii, Trichocereus scopulicola, Trichocereus tarmaensis, Trichocereus cuzcoensis, Trichocereus huanucoensis, Trichocereus pallarensis and many, many more!

The printing costs are somewhere between 10.000 – 12.000 Euros and that´s why I started the campaign on Indiegogo two days ago. Now after just 2 days, the campaign already reached 69% of its goal and is getting new supporters every single day.

The number of available books is very limited. There only are 250 softcover books and 100 hardcover books available exclusively through the campaign. The hardcover books already sold out but I managed to add a few that I actually wanted to put in the Trichocereus shop. Both the softcover version as well as the hard cover version are available for a reduced crowd funding price to say thank you to all the backers. The soft cover version will costs 58 Euro (+shipping costs) and the hardcover version will cost 88 Euro (+shipping costs). Both versions will be printed on high quality paper and with high quality ink. But because of the increased price of the hardcover edition, I could use an even better paper- and ink quality as well as some thread stitching to provide a higher value for the collectors. All the hardcover books are limited, numbered and signed as way to thank you for your support!
There also are package deals and re-seller packages to make it easier for shops or group-buyers to buy it. The books will be printed in June and the shipping phase begins in June or July. If you are not able to participate in the campaign due to whatever reasons, just let me know and I´ll try to find a way to make it work. It´s important to me that everyone who supports this project will actually get one.

Alright guys, it counts now and if I can´t get the campaign funded, the books won´t look as brilliant as they will when it reaches its goal. So please support my project on Indiegogo. The crowdfunding campaign will run for 60 days and I hope to reach the goal within the first 2-3 weeks. If you have any questions or just want to get in touch with me, you can reach me through EG [ät] You can also get in touch with me through our Trichocereus Facebook Group!
