Re: [Aroid-l] Dieffenbachia hoffmannii photo?

From: "Tom Croat" <Thomas.Croat at mobot.org> on 2010.03.15 at 16:37:48(20756) Dear Steve: I know nothing about the origin of that image but I might not even be D. seguine. That species has at least 3 distinct features, a sharply sulcate petiole, a protrudent spadix which is somewhat clavate spadix and a bilocular ovary. Other than that it is highly variable.

Due to confusion over the link I gave for a photo of Dieffenbachia seguine I located another from the Missouri Botanical Garden. At least to me, this photo resembles the photo posted of "Dieffenbachia hoffmanii" from Graf's work. http://www.mobot.org/gardinghelp/plantfinder/Plant.asp?code=B589 Steve www.ExoticRainforest.com On 3/1/2010 01:19, John wrote: I cannot give a source for the name Dieffenbachia hoffmannii but I have in the 60s and 70s grown this Dieffenbachia, in fact it was a favourite of mine. The name is no longer valid, if it ever was, but D. 'Exotica' or 'arvida' may be a mutation of it, whatever it is. Both are said by Graf to be from Costa Rica. The accompanying illustration may perhaps answer questions about markings on stem and petiole.
