Dear Windy,

The attached photos are fine this time, thanks.
I`ll need opinions from others on this, but I believe that the plant you may
think is Colocasia gigantia may in fact be a species of the Neotropical
genus Xanthosoma, NOT a Colocasia sp.
Also, what you think might be a hybrid may in fact be a seedling of your
Alocasia cuculata. My reasoning is that this species is well known for its
MANY leaf variations that sometimes occur spontaniously, so this may just be
a plant that grew from seed dropped by your parent plants, or even an
off-shoot which has mutated producing leaves of a slightly different shape
and texture. The count of veins of the anterior lobe of the leaf blade ( 4
per side), in fact all the veins of the suspected hybrid, closely match
your A. cuculata, just the shape is different.
The anterior lobes of the leaves in your photo of what I believe to be a
species of Xanthosoma have 10+ plus veins per side.
Have you seen blooms of the smaller plant as yet?? An examination of the
spadix will give additional information.
Also see if the suspected Xanthosoma has blooms, as the spathes of
Xanthosoma are VERY different to Alocasia OR Colocasia.

The Best,
