  Alocasia macrorrhiza or odora
From: Eric Schmidt <leu242 at yahoo.com> on 2004.12.20 at 21:13:26(12481)
Is this Alocasia macrorrhiza or odora in the photos?
It is growing naturalized in a nearby swampy area.
There are 2 big patches of this Alocasia.

What is the main differences between the 2 species?

Looks like A. odora to me; wonder if you could send me a piece (to expand my
gene pool for breeding)?

Hi Eric,

Looks like odora - glaucous spathe and peltate leaf, though the peduncle seems unusually short.
macrorrhizos only has peltate leaves as a seedling and the spathe is not glaucous. Odora is much cold hardier too.

This is A. odora in 95%
When not in bloom you can distinguish them by leaves
A. odora had slightly peltate leaves, macrorhiza not
what is easiest to see in young plants, because an adult
A. odora sometimes produces almost non-peltate leaves
The inflorescences are more different:
You can compare them here

Thanks for sharing.
Never seen a naturalized A Macrorrhiza in a swamp.
There are many A Indica specimens growing wild around
here but not a single A Macrorrhiza.

Hi Asit

The naturalized Alocasia in FL is macrorrhizos (indica = macrorrhizos). The
give away for macrorrhizos is that there is no 'ledge' of tissue in the leaf
sinus (the open part between the lobes of the arrow-head-shaped leaf)
