RE: native North American aroids


here are the native aroids, as I understand them:
    Calla palustris, in the far north.
    Symplocarpus foetidus, in the East.
    Acorus calamus, in wet spots wherever.
    Arisaema triphyllum; some writers divide this in
two or three species; Eastern.
    Arisaema dracontium, also Eastern.
    Orontium aquaticum, mostly SE
    Peltandra virginica, Eastern.
    P. sagittaefolia, SE
    Lysichitum americanum, the only Western native.
    Pistia stratiotes, subtropical FL
  
    A useful category to add might be the naturalized
species, which are capable of colonizing new habitats
and reproducing.  Maybe a good hypothetical question
to ask about them is 'would they persist if people
disappeared?'
     I'd consider chief among these:
     Zantedeschia aethiopica, in CA
     Colocasia esculenta or close relatives, through
the warm SE and FL
     Pinellia ternata, in the NE- NY and NJ and
spreading.
      Anyone seen others going wild?  As was said
before, in warm FL the number is legion.
