Hello, I've been searching photos and the spinossisima's I've seen have no hooks, maybe it is this one another subs. different than pilcayensis?

Thank you

I've grown many plants of this genus. Sometimes hybrids are a possibility, so you can never be positive on an ID. The reason I gave my assessment was because that species is likely involved with something similar. Many times you can find occasional hooked spines on Mammillaria spinosissima. It's relatives have a variable number of hooked spines such as M. nunezii, M. crassior, M. guerreronis, and finally with a numerous amount such as M. magnifica. I hope I didn't "muddy the waters" too much.

Interesting. At first sight I said to myself "pilcayensis". Next I saw the hooked spines and said "no".
Interesting to think in hybridization with the more closedly related species of the same group.

On the other hand: there is not any other Mammillaria with hooked spines it could be? I mean, more likely than assuming hydridization?

There are so many Mammillarias...I couldn't tell whether these plant doesn't fit in a "pure" species or not...just giving material for discussion here.
