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.

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.
