All I can think of is honey-locust (Gleditsia triacanthos), but these leaflets are much larger and I don't recall seeing any doubly compound leaves. Is there something else it could be?
That sounds right. I was thinking Juglans nigra had a terminal leaflet, but I see now it's not always present. Thanks!
Hi Michael, You might be right with Juglas nigra, of course. I suggested Pterocarya for two reasons - leaves and fruits, -- we see no fruits. Susan G was taking several photos of different parts of the tree for help in identification and walnut fruits remained unnoticed to her, both on the branches and on the ground. I thought this is unlikely. While Pterocaya fruits are mainly on the ground this time, they are much smaller and much easier to overlook.
