  Hello. I've noticed that there are several iNaturalist observations of Toxicodendron pubescens in New England and New York (northeast of the USDA database's range limit of New Jersey). Most of these look more like T. radicans (to my unexperienced eyes) however a few have larger rounded lobes on the leaflets, more like other images of T. pubescens. Do you have a sense of how reliable leaf shape is here? Is it likely this plant has populations in the northeast? Thanks!

  Dear MatthewS, good morning. Thank you for this comment. I would be interested in discussing this with you further--perhaps we could initiate a conversation at ahaines@nativeplanttrust.org. We could examine specific posts and determine which species are actually being discussed. Best wishes.
