This is a photo of a plant sent to me last year from Amante Darmanin. He thought it could be M. san-anglensis. Its not a species I have grown or seen before. Is anyone able to confirm it or offer another suggestion.

haageana DAR 091a, aff san-anglensis Dar_0910



haageana DAR 091a, aff san-anglensis Dar_0911

The location is possible Colonia De Los Curuces. Amante can not rember which State it was in but the general area is east of Mexico City where the States of Hidalgo, Mexico, puebla and Tlaxcala all meet up. On the top of a steep hill where Agave vershafeltii also grew.
If anyone could shed some light I would be grateful.

Oh dear!! Here's the old bag of worms, and they are still wriggling eh?

I have only seen this species in Puebla, south of the city, and around Tehuacan, a good distance from where Amante found this form. My view, based on the degree of variability I saw in this area, both at the same location,and at different locations, is that this is such a variable species that to divide it into subspecies has no real validity. I'd expect that it would continue to be variable in other parts of its geographic extent.

Reppenhagen uses elegans as a species name to include dealbata and san-angelensis; Hunt used haageana ssp. elegans to include collina, but now (New Cactus Lexicon) scraps all previous subspecies in favour of a single highly distributed and variable species under haageana.

So, I don't really think you are going to get a satisfactory outcome on this. Sleep
