Alocasia aquino

I purchased this from Glasshouse Works in June, 1996.  It now has 4 offsets.  It's growing in a bit too much light and so the leaves are doubling back on the petiole.  It had a bit of a rough start last winter.  I had left it outside until the nights were dipping into the 40s.  It killed an amazonica but the aquino survived. 

I understand that it's also been called Alocasia corazon.
