Alocasia longiloba magnifica
I obtained this from Dewey Fisk, August, 1997. The leaf is
something like lowii and argyrii but narrower and longer. I presume that as the
plant gets older the difference will be far more apparent. There's a new fat leaf
coming out. Once it's out, I'll upload the new image given that this leaf will be
unblemished as opposed to these two that were slightly burned.
