Elaine,
Your plant is sometimes sold as "Alocasia bullata". I have a hybrid of it crossed with Alocasia micholitziana 'Frydek', done by Brian Williams years ago. I couldn't resist the fun of crossing that hybrid with my hybrid, Alocasia "Imperial Giant". But my real goal is to cross Brian's hybrid with A. odora.
Here's a link to my page on Brian's hybrid:
