Dear Christiaan, Thanks for letting us know about this site. I see that they accept this taxon: Bowiea volubilis subsp. gariepensis How does this subspecies differ from the typical ssp volubilis. I see that their distributions do not quite touch, but what physical characteristics. And it doesn't mention B.v nana at all. Any thoughts? More questions. Jim W. -- Dr. James W.
