Re: Lithops hybrids

Ian, for the genetic work on Lithops , do you know of anything published after the 2010 Kellner et al article? I think that particular paper is decidedly dubious as a starting point for any revision of the genus. There are a few pairs of Lithops species that can be hybridised in cultivation, but th...

Re: Lithops hybrids

The best Lithops, in our narrow sense of the word, seem to come from selective crossing within species and even within particular forms, inbreeding rather than outbreeding. Steven Hammer produced 'Blacktop' from L. lesliei var venteri, but they were more of a browntop for me, the windows being nice ...

Strange species, obviously believes in not working its pollinators too hard.

Re: Conophytum fowering already - is this normal?

C. bolusiae is another one. Mine are never exactly prolific with flowers but this one is intent on taking it to a whole new level.

Re: Lithops hybrids

There is certainly potential for lumping Lithops, but the reasons why it hasn't been done are well-known and widely-accepted. The very difficulty of crossing any particular pair of Lithops species speaks to their being well-differentiated. Infra-specifically, Lithops subspecies are defined (followin...

Re: Lithops hybrids

Forum software messed up again (internal image names do not match actual image names). I've edited the post, pictures should go with the correct captions now.
