Thanks Evan! I hope Lari Ann sees this post because she's an Aroid expert and will more than likely be able to offer advice regarding jf's plant.
My first thought was Alocasia because it reminded me of my
Upright Elephant Ear (Alocasia macrorrhizos) but I really don't know an Alocasia from a Colcocasia and I have trouble comparing photo's most of the time.
I've seen EE's growing in full shade as well as full sun down here in Florida but I don't really know what causes leaf problems ... I just remember hearing about that virus which affects some aroids and the leaf photo's at that link resembled the leaves of the plant in jfried286's photo.
