I bought this Mammillaria sp. 2 weeks ago.
Tubercule arrangement: I found spirals 8 – 13
Radial spine: 7 White creamy with black tips.
Central spine: 2 Brown with black tips. Upper one 1 cm curved and lower one is 2,5 cm long, straight.
Not seen flowers
I want to learn name of this sp.
I suspect M. magnimamma, M. winterea, M. melanocentra ssp melanocentra or M. mystax spp casoi? not sure.
Thank you for replies.
