Guys I'm gonna need your help on this one. I have bought this plant about 11 years ago but it still eludes me what it really is! It is solitary, 24 cm (10") tall and currently in bloom.

Thanks in advance for your time.

Mark.

I think that is M. chionocephala, which some think is just a form of M. formosa, but M. chionocephala is for me rather different, taller growing, and solitary.

Thank you for your answer Chris! I'm still a bit confused as the pics of M.chinocephala I've Googled seem to have some differences with my plant, mainly at the spines and the amount of wool. Is that a natural variability? Is there also a chance that this is M.formosa ssp. pseudocrugicera or M.lloydii or even a hybrid?

Possibly. Also light and other conditions of cultivation (soil, watering) could change your cactus appearance.

I agree that it isn't typical chionocephala, which is why I wrote "I think" rather than "it is".

It has the right number of central spines, but is short on radials as far as I can see. The flowers look right to me though. M. formosa usually has more cntral spines and its flowers are creamy white rather than pinkish white.

I've seen plants like yours with the name of chionocephala, with fewer radials than the description. As Agrippa says, cultural conditions can affact spine growth and the amount of wool as well.

But I can't place it anywhere else at the moment, I'm afraid. Where has it been growing? In full light in a greenhouse, or indoors, even on a bright windowsill?

Chris this plant has a bit of a history. I bought it back in 2001 in the UK where I was living at the time. The shop I bought it from had its cacti indoors, with no direct sunlight and generally neglected. However I didn't notice any sign of etiolation. Then in 2002 I brought it back with me in Greece, where it is happily living ever since Very Happy . So for the past decade it has received lots of hours of full sun, average water and specialised fertiliser. Its substrate is very well drained sandy loam mostly.

Here's some pictures back from 2001, just in case you find them useful. Quality is pretty bad, since we're talking about scanned old pics but you can get a general idea of its early days! Lol!

Hope this helps a bit.

OK, so scrub that theory!!

I think that having seen the old photos, I'd still go with M. chionocephala, possibly formosa, as I don't have anything else to offer. But I'm not totally convinced. Sorry I can't do better.

I really appreciate your efforts Chris! I'll call it M. chionocephala for now and who knows maybe in another ten years of growth it may give us another clue!
