Poison Ivy

[Bill Williams]

What's the proper scientific name for the poison ivy commonly found in
Maryland?  Brown and Brown's "Woody Plants of Maryland" uses "Rhus radicans
L.," but many locals seem to think it should be "Rhus toxicodendron L.,"
which Brown and Brown call "poison oak," and say is "uncommon."
