L. williamsii?

[Melt In The Sun]

Hi all,
I've looked at the Lophophora guide at the top, and am still uncertain. The two photos below are: 1) my plant, clearly pink flower and sort-of defined ribs; 2) other plants from the same source, including two closed but clearly pink flowers, but plants with less-defined ribs.

Seems like ribs would lean toward diffusa, but flowers williamsii. Hybrids all? Thanks for any help.

Possibly williamsii they are fairly variable but something about the flowers makes me think lophophora fricii.

Looks a bit too red a flower for L. williamsii which is usually a paler pink. It looks more like L. frickii as diffusa has a whitish flower?

Left to right. L. williamsii, L. frickii, L. diffusa.

Lophophora's can also change the appearance of their ribs depending on how old they are and how turgid.

Thanks all...certainly looks like L. frickii fits the bill.

Melt In The Sun, your plants are two wonderful Lophophora fricii.

And speaking about hybrids:

There is impossible to cross diffusa and fricii. Fricii could be crossed only with koehresii, but those plants have different ribs pattern and different flowers (not your case).
You plants are pure Lophophora fricii - they have more pale epidermis comparing to williamsii, they don't have S-form ribs (so they aren't diffusas) and they have classic fricii flowers Or yeah, and those diagonal notches between areolas on a rib - that's also a fricii case.

There is one presumed Lophophora hybrid with a pinker flower, at least so far it has never been found in habitat, therefore artificial selection or hybridisation in cultivation is presumed. That is Lophophora jourdaniana:-
