Tropicals & Tender Perennials: What is this?, 1 by gothqueen

This is a single very very juvenile leaf of an unknown aroid a friend of mine has had in her collection for many many years. She has never known what it is. She thinks she recalls buying it years ago at either Marie Selby Gardens or Fairchild Gardens at a sale.

Although the leaf here looks tripartate, the mature leaves are much further divided and the plant gets very very large, about 3 ft tall. The stems are pictographical, like the stems of things like Alocasia tigrina and Alocasia Nishihira and others

My friend is moving out of state and is giving me starts of some of the more rare things that she has before she goes.

We do not even know the genera. We only know that it is an aroid.

Any ideas?
