Strange Find at Local Nursery, possibly Lophophora?

[Driller64]

Found this odd one at my local nursery in the cacti section. I have found a Melocactus here once so it is not out of the question that this is something exotic. Could it be a Lophophora?

I would put my money on a Matucana or a Gymnocalycium. Probably the latter.

Not a loph in the states. Gymno baldianum would be my guess. McNaughtons? Sue

[Driller64]

Yep, Mcnaughtons

[oldcat61]

They can be hit or miss. Check carefully for mealy bugs or spider mites; they are fairly lax about spraying. Sue

Notocactus uebelmannianus aka Parodia werneri aka P. crassigibba is another possibility.

Parodia crassigibba was my first thought too.

It does have the look of Parodia crassiggiba (Notocactus crassigibbus) but mine is fully spined from the top of the plant whereas Driller64's appears to be bald until the new growth matures. The proof will be when it flowers.

I was using P. crassigibba as a bit of a catch-all, to include P. werneri.

I wonder if the lack of spines on top is abit of "gardencentreitis" because it seems to have no spine growth at all until there are suddenly mature spines on the sides.
