Christiaan, I would greatly appreciate seeing an explication of the rootstocks of these plants. I have one or two Oxalis that never proliferate and essentially are unchanged after over ten years of cultivation. I wonder about these in terms of acting like bulbs, and also, if they replace themselves each season they are better considered as something other than bulbs. If most of the living tissue in the structure is *stem tissue* rather than leaf bases or modified stipules, combined with annual replacement, then they would have to be corms, no? Dylan
