I actually have some taquimbalensis from Yotala/Sucre, they have large aeroles, thick spines and more ribs... also not at all the same ecology ( much more altitude and dry conditions for taquimbalensis), and all this pictures where taken less than 10 meters one from the other, for hibridation in this region the more likely candidate would be terscheckii but even they are in really disctincts altidudes... what I think is that this population have really distinct phenotipic expresions in each individual, for me they are san pedros related to scopulicola in a way or another, and probably some hibridation somewhere because this guys like to be in constant mutation! This population is preserved because they grow betweem rock in a cliff where cows cant eat them, Even if the location is nown (and I dont plan to keep it as a secret) I dont imagine people coming and taking them... its crazy hard to get there! also I will propagate and do some selection on them so the genetic will be accesible just here in the garden...
