I have a couple of Lithops ultimately from Sonia Barker-Fricker which have "F" numbers. I assume these are Frik du Plooy, can anyone confirm that? If so, are they meaningful, and if so is there a list?

Thanks Derek.
Pruning I assume is the way forward?

In all the editing I lost the heartfelt

"Thank you to all for the help".

Adding the quote somehow erased it!
Again thanks, the online place for reliable C&S info.

David - why do you doubt the name on the label, apart from its gender? I've had at least 3 pygmea/us before and I think DT has reassigned each to a different species, so just suspicious of the veracity of the name! I think it has been applied willy-nilly to small plants - or perhaps I have just bee...
