A few years ago I acquired some Crassulas, many of which were clearly wrongly labelled. I've only now started to get down to sorting them out.
I don't know much about this genus, other than I've got from Gordon Rowley's book, which is good, but I wish had more photographs and a "confusion species" section. Can anyone help me put correct names to them please? For starters, is the attached pic just another of the many forms of C. nudicaulis, or is it something else? It is a distinctive yellow-green colour compared to all the others I have.
Many thanks!

Re: Calling Crassula experts
Thanks Elizabeth. Looks like that might be a match- not illustrated in Rowley's book.

Re: Calling Crassula experts
I have to say that C. rogersi was also my first impression, too.

Re: Calling Crassula experts
Been busy in the Sperrgebiet Ralph.......but DT is "the man" with these, I'm just his apprentice with Crassula
Looks like a reasonable ID to me but see what DT says.

Well, I would value both of your opinions equally.

Re: Calling Crassula experts
Yes, that's the one. I did manage to get a photo of C. rogersii into Gordon's Crassula book on p.228, the Supplementary Species section near the end and insisted he correctly named my photo on p.87, which he included under C. atropurpurea for some unknown reason.
Nice to see your greenhouse on TV, Paul D. and good to hear you're back in one piece, ChrisR!
Best wishes,
Derek Tribble

Lucky you - I had my planned trip there with Graham Williamson cancelled at the last minute ...

Re: Calling Crassula experts
Thanks all. Here is the next one, bearing three labels no less! C. brevifoila, C. nudicaulis v. herrei, and C. grisea. Suspect the last is correct?

Re: Calling Crassula experts
herrei......nothing really to do with nudicaulis seems to be the latest opinion.
