Re: Alocasia of Thailand


The x would indicate that they are stabilized hybrid species (nothospecies)
as, for example, the situation with Cryptocoryne x purpurea (a nothospecies
resulting from the stabilization of the naturally occurring hybrid C.
cordata x C. griffithii) this is not the case. Alistair and are both pretty
much convinced that A. cucullata and A. macrorrhizos are stabilied cultigens
(cultons) of A. odora. In cultivation thus they COULD be cited a A.
'Macrorrhizos' and A. 'Cucullata', but that would then lead to problems with
cultons of these. Best to leave the situation as is.

I was just reading over your fascinating paper on Alocasia in Thailand 
about both Alocasia cucullata and A. macrorrhizos not being valid 
species.   If this is the case and they are old cultigens, why would 
they not be properly written a Alocasia x macrorrhizos and Alocasia x 
cucullata with an appropriate cultivar name for the clone in commerce?
