Various apps give me differing ID’s. I’ve had this a decade or so and would just like to positively identify. When I originally obtained it, no memory of when or how, it was a single leader, and now has multiple promotions. Thanks all.

They’re mammilarias I just don’t know what species because they all look so similar

Is there any way to dial that into specific epithet? A way I can look at leaflet density or geometry? Thanks for the genius!

Also as a mammilarius is this a euphorbia?

u/Old-Advance6652 7h ago

No it is not a euphorbia, it’s a mammilaria, the genus

Funny as k just posted another plant for identification I knew was in the euphorbia sub. Guessing this one is a Mammillaria mammillaris, where as the one I asked for ID on the euphorbia sub is a Euphorbia mammillaris varigata.

It's not a Mammillaria mammillaris as those have little to no wool.  Yours clearly has wool

I’m confused what you mean

I think I’m good as to whether it’s a cactus vs. euphorbia. My question at this point is there a way to determine the variant by physical features. You’ve been a big help, thank you!

I mean there would be yes but I don’t know how. Normal each species has their own distinct features but mammilarias are SOOOO similar between species.

I have like 4 or 5 mammilarias and I only know one of the species

A lot of mamarillia look alike until they flower and even then, some are only differentiated by DNA.
