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@, 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.

The Best,

Julius
