Re: Ulearum donburnsii

From: "Randall M. Story" story at caltech.edu> on 2002.05.15 at 19:00:58(8799) Really?? WOW!! I was under the impression that A. bulbifer was sterile due to a chromosome count 2n = 39 (mentioned in Wilbert's Aroideana article excerpt: http://www.aroid.org/genera/amorphophallus/amcult.html ) and that it produced seed only vegetatively. Did the pollen come from the Ulearum or the Amorphophallus? +More Does that mean there is hope for other intergeneric hybrids? I have some Sauromatum pollen as well as more Sauromatums, a Dracunculus and unless I am mistaken, an A. bulbifer about to bloom. The A. bulbifer is from a 3 inch (7.5 cm) tuber (purchased from Odyssey bulbs) and has what I think are a growing peduncle and unopened spathe of approximately 2 1/2 inches (6 cm) and 3 inches (7.5 cm) respectively. It shows no sign of root development and appears very different from another A. bulbifer which I believe is putting up a leaf. A question on the A. bulbifer: If I don't remove the inflorescence and it makes fruits/seeds, will it fail to produce a leaf this year??
