Dear David and Robin,

Is there any chance David of your posting pictures to the wiki of O. 
cathara, O. gracilis, and  O. heidelbergensis?

Thanks for your responses about the checklist. I have ordered it as it 
sounds like it would be helpful for my collection and for adding 
information to the wiki as well. David's example is fascinating however as 
I found several sources on my computer who described Oxalis crassipes as 
South American. Please help the rest of us in deciphering how to use your 
information. One reference from 1884 describes this as from tropical 
Africa. The second description indicates that a plant named as O. crassipes 
is really a form of Oxalis hirta. And then you have a third reference to a 
plant named Oxalis articulata forma crassipes. But there was no mention of 
where this plant is from.

So what are we to conclude is the correct name for Lauw's plants, the ones 
Andrew B. is talking about and Uli's and presumably the ones in my archives 
that were recommended for the south. Are they all the same plant and should 
it be more correctly named Oxalis articulata forma crassipes?  Or is this 
plant really Oxalis hirta?
