More help......

Can you help me to identify these plants?




The second has no central spines.



Thank's

Referring to my previous reply to your earlier question, I mentioned Mammillaria supertexta. These both look closer to that description, the first one has, I think, 2 very short central spines. The presence of central spines is variable in M. supertexta, but that name is probably the closest I can get.

As you don't have any field numbers associated with them, they could also be the result of cross breeding between similar species. I haven't seen any forms of M. albilanata without central spines, so I'm ignoring that name in these cases.

Hi Chris, do you think that the second plant may be a M. supertexta?

In Hunt's New review of Mammillaria names, 1983, he makes the following comment inregard to M.supertexta...' Dr Lau has collected a variety of plants of this affinity, with and without centrals ( spines ) in North Oaxaca.... '
and in The New Cactus Lexicon....' Forms with csp + - 5mm and without csp grow together '.

Has Chris points out it is impossible to say for sure what species this is without any data.
I would suggest that you label the plants M. aff Supertextae.

Agreed, Tam.
