Mammillaria magallanii v. hamatispina Rog 088

M. magallanii v. hamatispina Rog 088 from West of Saltillo - Coahuila with not very wide open flowers:

Hello Hugo. Nice plant- still, as far as I know v. hamatispina should have a hooked central spine- which is missing in this case...

Hugo may not reply to your message, Laszlo, as he no longer grows Mamms.

The presence of hooked spines seems to be a variable character in these Lasiacanthae plants. I don't know what dictates when a plant decides to grow hooks.

I rather suspect that this variety was named as a result of finding some plants that had hooked spines, but actually there probably were others nearby that lacked hooked spines.

I have seen both hook spined and straight spined plants growing closely together in the magallani populations and also in the stella-de-tacubaya populations. I'm doubt if DNA tests wouldn't show any difference.

my mammillaria magallanii v hamatispina.
this is not from Helmuth Rogozinski collection.
in this plant there is an hooked central spine....






this is an old plant in my collection.
one central spine in present here.

Really very nice plants, Maurillio. Great examples of the hooked spined form.

Thank you very much Chris and Maurillio!
I too have 2 specimens of magallanii Rog 088- one of them lacks the hooked central, the other has it. I will post some photos later.
