This one is another confusion. I have this one also some where Mammillaria bocasana.
200 recognised species, 171 known species.
#1. Mammillaria amajacensis .
#2. Mammillaria hahniana.
#3. Mammillaria melanocentra.

Will be needing this latter when I find that white fur spine ball in the morning. Janet if Lynn takes a look at Mammillaria sempervivi 2 and the rest in bloom
.
I have a feeling that this one will cause a bit of fun. Lets give some time for the others to comment.

Masud.
