Soon (early April 2003) I will publish the name x Ulephallus malodorus Hett. You would not believe it but it has large, variegated, dissected leaves with bulbils all over.............

From: Betsy Feuerstein ecuador at midsouth.rr.com> on 2002.05.15 at 18:59:27(8798) Perhaps the difficulty is our definitions of 'quite small.' Or perhaps it is growing conditions in the wild. Or perhaps it is the use of fertilizer. I have not seen the specific plant you are referring to. I have many Ulearum Donburnsii growing in my greenhouse and I am using them as my reference along with my experience in the field at the local it is known from. It is wonderful that the leaves on your plant are bigger than those that I am aware of. Since we are talking of less than one inch, I might think it has a bit to do with individual leaves, and individual plants, and individual growing conditions, ....and individual perceptions.

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??

From: mburack at mindspring.com> on 2002.05.15 at 21:05:15(8801) Strange... my bulbifers always put up a leaf regardless of seed set... But then again, all my plants are screwed up.

From: "Wilbert Hetterscheid" hetter at worldonline.nl> on 2002.05.16 at 03:11:41(8804) O.k., well then I stand corrected. I've never seen it happen here with about 30 plants of bulbifer. neither with its direct relative muelleri. But a screwed up amorph is far from unbelievable.

From: Durightmm at aol.com on 2002.05.16 at 19:24:27(8810) A.bulbifer seeds?? I have been under the impression A. bulbifer does not seed but rather, as with dandelions, produce veggetative parts that are simply called seeds. I have collected and grown them on occassion and found them to be unseedlike but vigorous growers. Is this more a botanical technicality? Joe

From: "Plantsman" plantsman at prodigy.net> on 2002.05.16 at 20:58:50(8812) Are you sure about the dandelion seed thing? I thought what they produced by the millions in my area were seeds. They sure look like seeds and accomplish the same pesty purpose . I mean, they are the result of the pollination of the flower. I've never heard this proposition put forth before.

I just figured this out--maybe my cold or the pseudoephedrine (AKA Sudafed) I am taking has fuzzed my brain up. For some reason I thought that April 1st is a uniquely American "holiday"!!! still, A. bulbifer is triploid, right?
