  New Dark Alocasia
From: LARIANN GARNER <AROIDIAN at worldnet.att.net> on 2007.05.26 at 14:16:57(15723)
Fellow Aroiders,

I found this Alocasia at a mom n'pop nursery in south Florida; I had
gone there because they seemed to have a lot of Colocasias and
Alocasias. This plant stopped me in my tracks, and of course I got one
for my work at Aroidia. Has anyone ever seen this plant or know the
species? I'm confident it is not Alocasia plumbea Nigra, or the one
people are calling "Jurassic Dark", which is supposed to be a variety of
Alocasia plumbea Nigra.

I think that it is a chimeric variegant of Alocasia sarawakensis, based
on morphological similarities. Once I see it bloom, I will know for sure.

Here's the link:

Thanks!

What a wonderful-looking plant! If its not a hybrid it certainly looks like alba or sarawakensis. I was interested to see you say it was not alba: not disagreeing with you, but why not?

Alistair,

I have the plant right next to a robust specimen of A. alba and the
morphological differences are quite clear once you see them next to each
other. There are similarities, however, as there are between A. alba
and A. sarawakensis. For me, the tell-tale sign will be the morphology
of the inflorescences when they finally appear. The A. alba actually
has much more prominent venation on both the abaxial and adaxial
surfaces and a heavier substance overall to the leaf than has this plant
or A. sarawakensis.

In some respects, one could say that this plant appears somewhat
intermediate between A. alba and A. sarawakensis, as A. sarawakensis
petioles have a rough, almost peach-fuzz texture and both this plant and
A. alba petioles are smooth to the touch. But then there is the color,
which is characteristic of neither of the two species in question!

I would argue against this plant being a hybrid, as one of the most
likely parents, A. plumbea Nigra, has never produced pollen in my
experience, implying to me that it may be a sterile hybrid itself, or a
sterile sport.

An intriguing enigma, for sure!
