Species
Cuzcoensis
One of the better-collected names in this genus, and one that has quietly absorbed several others.
The name
The International Plant Names Index records Trichocereus cuzcoensis Britton & Rose as a validly published name, first published in 1920. The current treatment accepts Trichocereus cuzcoensis and carries both Trichocereus knuthianus and Trichocereus tarmaensis in its synonymy.Reported by one source, and not corroborated anywhere else.
What has been found in the wild
Asked for Trichocereus cuzcoensis by name, the collectors' own field-number lists return 34 distinct collections from 6 collectors — 32 at Peruvian localities and 2 whose locality names no country. Some of those records are filed under the species with a second name in quotation marks after it — uyupampensis, puquiensis and schoenii each appear that way — so the collectors writing them were already treating those labels as forms within cuzcoensis rather than as species of their own.Reported by one source, and not corroborated anywhere else.
Names in the library filed under this species
These are entries where a source names this species for the plant. An entry is not listed here because its name looks like the epithet — that would be a guess, and a guess is what this library exists not to publish.
Every feature on this page moves with age, sun and water: a thirsty plant in hard light grows longer spines and a heavier bloom than the same clone in the shade. None of it settles an identity on its own, a clone name is not proof of a species, and a photograph is a pointer rather than an answer.
