Box Elder

Description:

About 17ft tall 1ft and a half in circumference. Has odd leaf patterns. Like it goes big then to one small that is the terminal leaflet. Yes it is a compound leaf. Hard to tell what the bark looks like because it is covered with moss. Its fruit is the helicopter seeds. The thing that makes this tree different its terminal leaflet doesn't stay consistent because it can have no lobes, be wide or skinny, it doesn't have a certain way. It is also an alternate branched.

Habitat:

On side of road. Growing towards the road to the sunlight sense beside it is a closed canopy.

Notes:

I was wondering what is growing on it in the third picture?
