Happy Easter - 2 mammis for ID/confirmation :)

Well, Happy Easter for all mammis lovers

First mammi i don't even know if it is a mammi at all:) If it is I suspect on Mamm. sphacelata ssp viperina. Bought (saved!!!) on a green market from a some peasant, dried, in a terrific soil,... Impossible to count the spines, even to see the color of the body. Here it is:





Second one is from the same source. I don't have a good idea - looks a little bit like erythrosperma but flowers are very interesting and I think don't match the type. Very small (5cm pot) nice flowering (flowers don't open full) and wildly prolifering??? About 12-13 radials and one longer hooked central white/yellow on the bottom and red on the top. Any guess???

You could well be right about the first plant. The dark spines turning white as they age, and the clustering habit do suggest M. sphacelata, not sure about ssp. viperina, but maybe once it recovers and grows it might develop longer segments.
Your second plant is striking some sort of memory, but I can't get it in to focus yet. I need to think a bit more about it...though the flower doesn't seem right with what image (vague) I have in my mind.
You certainly give us some challenges!

My suggestion for the second plant is Mammillaria oteroi

Yes, Ento, at least the flowers are right, though my M. oteroi plants don't look like this in the body, darker spines and tighter body. Could just be cultural conditions and natural variations though. I'd go by the flowers.

Mammillaria oteroi ml 351 in my greenhouse

After looking at the pics and the books - oteroi looks like a nice match Thank's Ento!!!

@Chris - yes there are some challenges for me also!!! Usually I buy plants without any markers. Some plants are very easy to recognize, but other ones (especially ones witch are not usually sold) are a nightmare. And this place is unique and precious for that kind of help. Thank's a lot for your time and good will for keeping this forum alive

P.S. More to come  

Absolutely right, Ento!
