Re: Xanthosoma

From: "Eduardo Goncalves" edggon at hotmail.com> on 2001.06.13 at 15:00:26(6697) Dear George, Yes, I forgot this one. It is the same species I am talking about, despite the individual featured in the picture is too young. The color is too striking to forget! However, I am still considering if X. mafaffa is not the same thing of X. sagittifolium. In fact, the X. mafaffa-sagittifolium-robustum-roseum complex is the most puzzling problem in aroid systematics, in my opinion. It may take me some time to solve. Best wishes, Eduardo. +More >Hi Eduardo, > >In the same website you cited below, there is a page featuring Xanthosoma >maffafa aurea which looked like the Golden Xanthosoma I saw (from memory >only, if you please).
