Calling Crassula experts

Post by Paul D »

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!

Thanks Elizabeth. Looks like that might be a match- not illustrated in Rowley's book.

I have to say that C. rogersi was also my first impression, too.

Where's ChrisR got to - he's the man! :grin:

Well, I would value both of your opinions equally. (tu) :wink:

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,

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

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?

herrei......nothing really to do with nudicaulis seems to be the latest opinion.
