Re: native North American aroids
As I recall at this moment there are the two species of Peltandra--P.
virginica and P. sagittifolia, Orontium aquaticum, Lysichiton americanus,
Symplocarpus foetidus, Calla palustris, Pista stratiotes, Arisaema with a
couple of species, and MANY introduced genera, i.e. Xanthosoma, Colocasia,
Alocasia, Arum, Dieffenbachia, Caladium, Syngonium, Philodendron,
Epipremnum, etc.. Hope this helps. If you have specific questions
perhaps about Aroids in a specific state, post again.
