NMCR 2010 poco – thelegonus

Gallery

Some more Trichocereus that were still at NMCR in 2010:
from poco albiflorus through thelegonus.

 

This is the final photo set of our 1 August, 2010 visit to New Mexico Cactus Research.
The featured image above illustrates how the cacti had overgrown some of their tags. Many of the plant tags were in rough shape, some were missing completely, some were missing a part of the tag and some had become illegible.
More images illustrating the new growth on all of the cuttings which Horst kindly provided will be coming in the future.

 

Trichocereus poco albiflorus

From Cuchu Ingenio, Bolivia. Tag also had the note “possibly Argentina”
Seeds had been collected by “DM” and were obtained by NMCR 4/1977, Horst planted them in April 1980.
Now lumped with Trichocereus tarijensis.

 

Trichocereus-poco-albiflorus-NMCR

 

Trichocereus riomizquiensis

FR856 type from Chuyllas, Bolivia (Rio Mizque).
Seeds had been obtained from Riviere de Carault in November of 1972 and were planted on the first of July in 1980 by Horst.

Trichocereus rubinghanus (I am presently unable to locate this name.)

Grown from seeds obtained from Riviere de Carault but missing a tag.

 

Trichocereus-rubinghanus-NMCR-2010

 

Trichocereus scopulicolus

 FR991 grown from seeds that Horst obtained from Riviere de Carault. They were planted in 1980. Date of seed acquisition is unknown due to partial tag destruction.

Trichocereus spachianus forma brevispinulus

Grown from seed provided by RIV. Horst described this as being an old form which is present in European nurseries.

 

Trichocereus-spachianus-brevispinulosus-NMCR-2010

 

Trichocereus strigosus

Seeds were obtained from “Lopez” in June 1976; they were planted in July of 1980.

 

Trichocereus-strigosus-NMCR-2010

 

Trichocereus terscheckii

“Cardon Grande” from Argentina. Seeds came from “Lopez” in February 1976; Horst planted them July 1980.

 

 

Trichocereus thelegonus

These production mothers were grown from seeds that NMCR acquired from Field in February of 1976. (This is also the featured image on this page.)

 

Trichocereus-thelegonus-NMCR-2010-f

 

This is what they can become when not repeatedly cut for sale.

I hope that you have enjoyed seeing NMCR!

Trichocereus pachanoi or pachanoids?

Image

  A representative few of the many interesting Trichocereus pachanoi or pachanoid offerings that are present in horticulture.

 

Trichocereus aff. huanucoensis
  This specimen is missing its accession data but is suspected by Jon Trager of being grown from seeds provided to the Huntington by Harry Johnson. 

 The pachanoid Trichocereus aff Huanucoensis

 

Trichocereus huanucoensis

  The next image is of another pachanoid plant at the Huntington. It was grown from seeds provided to them by Harry Johnson. 

 The pachanoid Trichocereus huanucoensis

 

 

   The image below is of a plant of Trichocereus huanucoensis at UC.
   This too was grown from seeds provided to them by Harry Johnson. 

The-pachanoid-Trichocereus-huanucoensis-flowering

 

Trichocereus pachanoi cv. Juul’s Giant
  The cutting shown below was harvested directly from a plant in Tom Juul’s backyard garden in San Francisco. No origin data exists but it is suspected of originating on one of the UC cactus collection expeditions but losing its collection data during transportation. These amazingly productive expeditions were cancelled due to criticism that it was inappropriate for an academic institution and commercial cactus vendors to be engaging in co-ventures (as opposed to the spectrum of other academic-commercial co-ventures that exist at UC outside of the world of cactus collecting.)

Trichocerus “peruvianus” Huancabamba (on the left – sp. Peru 64.0762 is to its right and behind it.)
  This entered horticulture via seeds collected in Peru during the 1960s by Dick Van Geest and sold through Mesa Garden over the course of many years. It is variable in appearance but is clearly far more a pachanoi than a peruvianoid.

   There is also some different material that
Paul Hutchison collected as live cuttings from Huancabamba

 

Trichocereus scopulicola
  This Ritter species is currently believed to be extinct in the wild. Or at least several sets of people have been unable to locate it including botanists searching on behalf of the Kew prior to the publication of Hunt’s New Cactus Lexicon. It is suspected of having been extirpated by freely wandering goats, as is the case for a number of cactus species.

  Seed-grown in England.

Trichocereus pachanoi
  Collected in the 1960s in Huamachuco Prov., La Libertad Dept., Peru.
Paul C. Hutchison, J. K. Wright & R.M. Straw 6212

  (UC Peru 64.0762)
This fat pachanoid specimen is no longer present in UC’s desert garden. The last time I saw it there the plant was suffering badly from heavy predation and the rot produced from careless and badly timed harvesting. This plant has been regularly sold via their annual plant sale so it is a tragic loss to all visitors to that garden.

 The pachanoid Peru 64.0762

 

Trichocereus pachanoi
   Collected in the 1960s in Bongara Prov., Peru
Paul C. Hutchison & Jerry K. Wright 4013
   (UC Peru 65.0729)
More recently this plant had its name tag changed to Echinopsis macrogona and, strangely, was given a new accession number and date. The plant itself, however, has not changed.

 The-pachanoid-Trichocereus-sp-Peru-65-0729

 

Trichocereus pachanoi Strybig
  I was told by the Strybig’s staff that this was obtained from UC. The most plausible candidate would seem to be  Peru 65.0729. However, that plant from UC has been demonstrated to show an interesting spiralling desiccation of its flowers that seems to be trasnferred through its progeny. The Strybig’s does not appear to have this feature. Whether that is enough to make them different or if they are one and the same remains to be proven through study.

Trichocereus pachanoi R. Montgomery; Peru
   I presently lack any additional data concerning what was said to be a field collection acquired in Peru many years ago.

Trichocereus pachanoi Torres & Torres; N. Chile
   This came from what was believed to be a wild collection made by M & D Torres at fairly high altitude in northern Chile.  It appeared to be a wild plant which, if true, would extend the range of Trichocereus pachanoi into that country.
(This is the plant that provided material for the article “San Pedro in a Pressure Pot”.)
