I know that you are speaking about a Colocasia X Alocasia cross, not the
other shown in the photos. Pete, if at all poss., check the other 'alleged
cross', as Dieffenbachia has 2n = 34, 68 chromosomes while Aglaonema has
2n=40, 60,80, 100, 120 (70, 110) chromosomes. I`m NOT good at
understanding the above, but they don`t seem compatable if you compare the
numbers. The sexual structures of the spadix also look a lot different
(the info. came from TGOA).

I can believe a cross of Alocasia w/ Colocasia, as these genera seem VERY
much alike, and the lines seperating these two genera are often 'blurred',
but the claim of Dieffenbachia X Aglaonema makes me wonder.

<<If it's the same group, a Japanese botanist reported on this hybrid at the
IAS Symposium in Kunming in the mid-90s. There managed to get very few seed
and even fewer seedlings but they were successful. the cross was C.
esculenta with I think A. odora but I'd need to grub out the proceedings to
be be sure.

The Aglaonema group is discussing now if Dieffenbachia can be crossed
with Aglaonema... I know that they belong to deiierent tribes and have
different pollination biology, however the Group says to me that the
Japanese crossed Alocasia x Colocasia (the same tribe). Does anybody know
anything about this Alo-Colocasia hybrid?
