Sorry to piggyback on my own post, but I found a photo of the glands
on Ailanthus:

Um, have you double-checked against Ailanthus, Tree-of-heaven? It has
pinnately compound leaves and orangey, flat fruits. You can confirm
it by the little glandular lobe at the base of each leaflet. It's an
exotic and very weedy in some spots. The trees can be quite large.
