enter image description hereenter image description hereI saw this growing out of a yard and onto the sidewalk. Is it Poison Sumac or non-poisonous Sumac? 11 leaflets, It has a smooth stem and leaflets so it is not Staghorn Sumac. I did not see any berries or fruit. Is there any of the poisonous kind around hear that I can see? Does It only grows in wetlands.

    Where do you live? To me it seems much more to Ailanthus altissima. – Giacomo Catenazzi Jun 04 '19 at 14:57
  • I am in Northern Maryland. And I think you may be right. It does look like Ailanthus altissima. I think the poison sumac needs wetlands to survive. – paul cappucci Jun 05 '19 at 19:03

    Ailanthus , It will have a chiastic odor if you crush a some leaves , which I think is unpleasant. Fast growing , relatively soft wood , relatively short life. – blacksmith37 Aug 13 '21 at 03:33
  • I haven't checked this post in a long time. Thanks for responding. I am in Rockville Maryland so this is Ailanthus altissima - http://mdinvasives.org/iotm/sept-2007 – paul cappucci Aug 13 '21 at 10:57
  • @paulcap1 if you think my answer is right I'd love you to accept it! – Marisa Aug 19 '21 at 20:40

The first image is absolutely a Wisteria spp. leaflet--you can see the vine the leaves come from.

The second set of pictures is not Ailanthus altissima; it's missing the characteristic knob at the base of the leaflets (almost like the thumb on a mitten), and there is a gentle serration to the leaves (which is completely absent in A. altissima).

Absent photos of the stem, I'm inclined to say it's Jugans nigra, or black walnut. Key features that make me believe this is the way the leaflet 'starts' earlier on one side vs the other.

I know this is resurrecting a question, but I was tracking down images to confirm an ID for someone else and it struck me that the person was actually asking for ID's on two different plants.
