Hi guys,
Is this a valid taxon? Is it any different to regular v. chloranthus other than the type of soil where it grows? Any way to ID?
Thank you
Echinocereus viridiflorus v. rhyolitensis
Re: Echinocereus viridiflorus v. rhyolitensis
I quote llifle:
"Echinocereus viridiflorus subs. chloranthus (Engelm.) N.P.Taylor: has 10-18 ribs, 5 or more central spines, giving the plants a bristly appearance, it is often considered a separate species (Echinocereus chloranthus). Distribution: W. Texas, S.E. New Mexico, and N. Mexico"
And
"Echinocereus viridiflorus var. rhyolithensis W. Blume & Mich.Lange: (Echinocereus russantus forma) Bristly red-spined plants from New Mexico"

Re: Echinocereus viridiflorus v. rhyolitensis
Yes it was validly published by Wolfgang Blum, Michael Lange, Werner Rischer and Jurgen Rutowin their book called "Echinocereus" in both German and English. The left hand columns are in German and the right hand in English. This is one of the best monographs on Echinocereus I have seen so far, but now out of print I think, therefore often offered at crazy prices secondhand by book dealers, I am certain I only paid about £10 when I bought it new, nothing like the crazy price in this link. With luck you may eventually find it on EBAY:-
https://www.amazon.co.uk/Echinocereus-M ... 3000019103
The authors are certainly splitters compared to say "The New Cactus Lexicon", but they illustrate virtually every form they describe.
I could not find it in their book as E. viridiflorus var. rhyolithensis, but like Tom I found the synonymy on llife as:-
•Echinocereus viridiflorus var. rhyolithensis W. Blume & Mich.Lange
◦Echinocereus chloranthus subs. rhyolithensis W.Blum & Mich.Lange in W.Blum et al.
Therefore I found it as they originally published it in their Echinocereus monograph under chloranthus, before evidently transferring it later to viridiflorus.
I don't have time to copy it for you at the moment, but will try and do so later. Their preamble says:-
"This taxon has been found in collections under the trade name of E. cowperi for some time. Above all as a result of the collecting activities of Kuenzler and Brack, plentiful seeds were already available before 1980, which thrived and provided us with our present knowledge of the taxon."
