There's controversy about the name of the plant. Some insist that it's Alocasia micholitziana. Others call it micholitziana "Frydek" and yet others insist it's just Alocasia "Frydek". I'm choosing to call it Alocasia micholitiziana "Frydek" for the following reason:
No one has indicated that this is a cross. If that's the case, then it needs a species name. On the other hand, if the wild occurring plant is difficult to raise and someone named "Frydek" identified a variety that's easier to grow, then I'm willing to give Mr., Mrs., or Dr. Frydek the due credit.
May 1998 - I've learned that temperature has some apparent effect on the degree of variegation. Towards the end of the 1997 growing season, I had left the plant outside perhaps a bit longer than I should have. (No, for a change it didn't quite get frosty out.) The leaves were barely variegated at all. I feared that the plant was reverting. I had heard from some aroiders that occassionally, variegated plants become solid green. Over the winter, the plant survived and grew on a kitchen counter top. All the leaves over the winter have had this same kind of mottled appearance. As the leaf gets older, the yellow fades to a cream color.
