IMHO, every plant I've ever known as Alocasia micholitziana 'Frydek' is in no way Alocasia 'amazonica'. The Frydek has bold white veins and distinctively velvety, dark green leaves, with no sign of red or reddish color anywhere on the plant. Petioles are pale green. It is not out of the question that some unscrupulous seller would mislabel one of the plants, though.

No amount of natural variation is going to make a true A. micholitziana 'Frydek' be another type of Alocasia 'amazonica', unless we are tossing out all criteria for determining what a species is. If we are doing that, then there is not much point at all in talking about "different" kinds of plants!

Agreed, but I've seen plants that appear to be Alocasia micholitziana in our local Home Depot and Lowe's on more than one occasion with an Alocasia Amazonica tag in the pot.

I just joined this cubit and don't see Steve's atrium. Am I missing something?

I once worked inmanaged a florist /greenhouse in Oklahoma.

We had philodendron growing in the soil under the growing tables. We hired a new grower and he came in and chopped them down. I literally bawled.
