not-so-variegated Alocasia micholitziana variegata

From: Lester Kallus <lkallus at earthlink.net> on 1997.11.20 at 00:25:30(1639) I have (or perhaps should say "had") a variegated Alocasia micholitiziana "Frydek". It came with one macerated leaf and an active growing tip. The next 3 leaves were nicely variegated and the plant continued to grow quite well. +More The last leaf to come out was solid green with some very faint lighter green discolorations. A new leaf now is also nearly totally green with little if any variegation. Do these plants revert? Have I spent a near fortune for a plant that I already had? Is there anything I can do to increase its variegation? The light level had actually increased when the variegation began to decrease. It was outdoors at the time and night temperatures were dropping into the low 50s. It's now indoors and the light level has consequently dropped but the temperature has increased. Les
