Discussion of aroidsOnderwerp: Re: [Aroid-l] Amorph titanum
flowering in Sydney, Australia
Hi Julius, I guess Wilbert is the person to
know to what extent smaller than normal Amorphophallus blooms are
female-sterile, though I have certainly seen small paeoniifolius, bulbifer,
variabilis and galbra producing fruits. This titanum had normal-looking
pistils, but one of our illustrators is doing a botanical painting including
dissections and I will ask her to look out for whether or not there are
functional-looking ovules.

Dear Alistair,
Thanks for the information and congrats on getting any size of a
bloom! I read where the spadix collapsed a very short time after
it opened, I wonder if this is not another sign of something I have
been observing in aroids in many species over many
years. I have suggested that many Aroids (the genus
Arisaema has taken this to the ultimate) will produce a smaller than usual
bloom that, though it may have female flowers (in Arisaema the female
flowers are NOT produced) , is never intended and in fact can and does
not produce fruit/seed, the small bloom only contributes pollen to the
genitic 'trail'. This might occur when a
plant 'senses' that it is stressed (too many growing seasons without a tuber
large enough to sustain the development of fruit/seed) or is growing in a
site less-then-optimum to producing a large tuber which is able to sustain
the length of time necessary for fruit/seed production.&nbs p; I
was wiondering if some dissections could possibly be done to the remains of
the female flowers on this or future small blooms to see if all the
necessary parts are there which might indicate if these female flowers could
ever develop seed. Just food for thought.
Good Growing!
Julius

result was pots toppling over as they bulged with swelling tubers, and one
(at 15.5 kg) producing a flower.

us! A happy event indeed. Perhaps Dr. Hay
(if he reads thsi) may be so kind as to try to determine from wence this
plant came, if by chance from a Jim Symon seed
collection? I`m sorry that you missed seeing this
amazing bloom. Any details as to how tall the bloom was, etc.??
