Species
Huanucoensis
This page is different from the rest, and worth reading for that reason: it is a name in common use that two separate reference indexes return nothing at all for.
The name index has never carried it
The International Plant Names Index holds no record published under this name in Trichocereus, and none in Echinopsis either.Reported by one source, and not corroborated anywhere else.
Nobody has collected one under it
Asked for it by name, the collectors' own field-number lists return no collection at all: nobody in that record has been out and numbered a plant under it.Reported by one source, and not corroborated anywhere else.
Why that is worth saying
Both of those are checkable negatives rather than an absence of effort, and both are re-read every week — if either index ever carries the name, this page is wrong and has to be rewritten.
What that does and does not mean
It does not mean the plants sold under the name are not real, and it does not mean anyone selling them is being dishonest. It means the word is a trade label rather than a published botanical name, and that nothing in the formal record fixes which plant it belongs to.
What growers report
One grower describes plants held under the name as carrying alternating short and long spines, with a distinctive lip or eye pattern around the areole.Too little stands behind this for us to confirm it.
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.
