Maybe Finger Cactus - Mammillaria longimamma

Are you agreeing or disagreeing? Dolichothele longimamma is a synonym for Mammillaria longimamma.

Agree on the subgenus, disagree on species. Kind of too skinny and frail and wimpy to be that one.Decipens or mariner- lapostollei or something. Spines are not convincing enough for me....

It came to me as Dolichothele camptotricha (which didn't seem right) so I was also thinking decipiens. Maybe we need to wait a while to know.

camptotricha is a ssp. of decipiens I think, these days.

mammillarias.net

is a pretty good resource when it comes to Mammillarias...

It is what it is!

Thank you everyone for your input. I guess I should have gone with the name it came with, then. (In its modern form.) I had a big clump of camptotricha for years (it rotted rather unexpectedly) but the resemblance is not so obvious with this juvenile. Daisy, your picture shows the ontogeny of the spines in a way that makes a connection for me. And that is a really useful site, Thijs.

Did I just use the word ontogeny in a sentence?

I was thinking Mammillaria longimamma myself.

I think longimamma has a lot more spines compared to this one, but that is definitely not always definitive.

It is what it is!

Regarding other potential IDs, I think the question will be simpler when the plant grows up. Right now it doesn't have the adult number of spines, I think. And the tubercles probably seem more pronounced than they will be with time. The flower color will be definitive with respect to decipiens vs. longimamma (white vs. yellow) so I suspect everything will become much clearer once the plant becomes sexually mature.
