  Re: Homalomena/Dieffenbachia.

Dear Jonathon,

I have seen this plant for sale at a nursery here in WPB, Florida, it is
certainly a species of Homalomena, NOT a hybrid between two VERY different
genera/tribes of aroids! It is a very pretty plant, but seems sensative to
sun burn and fungus/viral problems. I believe it is produced by tissue
culture.
To my knowledge there has been one intergeneric cross in the Araceae, that
of Colocasia with Alocasia, and these are VERY closely related genera, so
close in fact that there is talk of 'sinking' one into the other. I have
also heard through the 'grape vine' that there was a claim made on an Asian
'talk group' that someone had crossed a Xanthosoma with a Caladium , but
because of the ongoing confusion if identifying plants of these two genera
decisivly (there is a Xanthosoma aristeguietae illustrated as a Caladium on
pg. 208 of TGOA) this claim is probably based on a misidentification of a
plant as belonging to another genus. Caladiums have their pollen shed in
monads (single globular grains) , while Xanthosoma sheds its pollen in
tetrads (groups of four grains stuck together), so I am informed that
cross-breeding between these two genera is highly unlikely.
We must bear in mind that research on aroids is an ongoing discipline, as
yet nothing (or few things!) are cast in stone!
Hope that this helps.

Julius
