Re: [Aroid-l] Dieffenbachia hoffmannii photo?

From: "Carol McCarthy" <Carol.McCarthy at mail.wvu.edu> on 2010.03.02 at 14:10:25(20684) Hello Steve, John, Conrad and anyone else reading along, I checked my database yesterday, I got the name from the same source John quotes; A.B. Graph's Exotica; page 172 of Edition 9 to be more exact. I will also note that the plant has been in one of two university greenhouse here at WVU for at least 15 years. From what I know of the collections, I do not believe that this material was collected straight from habitat even back then. Whether it was bought, traded for or a gift I do not have any records to enlighten me. The two professors who might know are both long retired. We have been doing an inventory update of the greenhouse collections and working on correcting and updating questionable names along the way. I guess for now, this one will stay questionable. This Dieffenbachia grows very slowly and has a different, deeper green than most. As the picture John attached shows a little, the petioles show stripes and or dots of lighter colors on the deep green ground color. Currently the plant is at another greenhouse across campus, I will try to get a picture of this plant, whatever it is, in the near future and post it. Since we have established that D. hoffmannii is not a valid name does anyone have any suggestions as to a correct identity? Thanks to a great group for any help at all.

The name is no longer valid, if it ever was, but D. ââ‚ ¬Ã‹Å“Exoticaââ‚ ¬Ã¢â€ž ¢ or ââ‚ ¬Ã‹Å“arvidaââ‚ ¬Ã¢â€ž ¢ may be a mutation of it, whatever it is.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.
