Oh, c'mon, WHO would want an Ulearum to smell bad??????? I did once cross
Ulearum sagittatum with Amorphophallus bulbifer and the result is indeed a
stinking beauty (Bonaventure and all hybridists, this is your chance to go
mad!!!!). 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.............

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.

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?

The hybrid product is the result of an autoplyploidisation event in the sex
cells of bulbifer and that followed by a reduction in the cross, leading to
a tertraploid hybrid result........ But maybe I haven't made myself clear. I
am going to pubslish it EARLY APRIL 2003........

As for a serious answer: bulbifer will usually not produce a leaf in the
same season when it is allowed seed set.

Strange... my bulbifers always put up a leaf regardless of seed set...

But then again, all my plants are screwed up.

Got it, I think. So actually 3n9 for A. bulbifer (triploid not


From: "Wilbert Hetterscheid" hetter at worldonline.nl> on 2002.05.16 at 03:09:58(8803)
Yeah, and 4n = 387.5 for the hybrid...........

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.

Be cautious, Oh Great Lord Phallus,

Your esteemed eyes are rapidly turning brown, and your nose it grows
exceedingly long!!!

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

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.

Okay, Okay, you got me. 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?
