very green Mammillaria/Coryphantha ?

[fabricius]

This one is a bit to green too be true, but is it a Mammillaria ?
In a 6 cm pot.

Thks for your advice.

It looks more like a Coryphantha, possibly C. elephantidens, but my knowledge isn’t the best for this species. Someone else might know better than me.

I thought Corpyhantha. Not C. elephantidens though, it has central spines. Perhaps one of the weaker-spined forms of C. longicornis?

[fabricius]

Thank you.
May be the flowers will help to confirm next year.

C radians IMHO (commercial, thick, overfertilized)

Hello

I read from several sources (LLIFLE for ex) that Coryphantha radians is a Coryphanta cornifera without central spine(s). The one I presented has central spines, so it would rather be a C.cornifera.

However, by reading the compared description of both C.cornifera and C.longicornis on LLIFLE, it seems to me more likely a C.longicornis.

The C.cornifera/radians I already own show more tubercles than this new one.

The plant of my post has 3 central spines and approx 12 radial spines, exactly as the C.longicornis described in LLIFLE. (although the C.cornifera/radians described in LLIFLE could also have 10-20 radial and 0 or 1( to 3) central spines.

I think I may have to wait for flowers and fruits to hopefully have a final answer...or not has it may be an hybrid.

Thanks for yr comments.

My guess: a somewhat light deprived Coryphantha pallida subs. calipensis

[fabricius]

Thank you.

I must say that the description I can read in LLIFLE for Coryphantha pallida subs. calipensis shows a very good match with my plant, specially the "pineapple form" !

But is also looks a bit like C.pycnacantha (syn C.andreae)....

Not easy, these Coryphantha's....
