Hackberry? Celtis species.

btw for future reference, please say where the plant you want identified is located. Geographical location makes a lot of difference to what it is likely to be.

eta the transatlantic time lag got me again. beng's definite id wasn't there when I posted.

i recall your ID pic.. refresh our memory.. of what your big projects were.. and how they turned out... perhaps bring up some old posts... i think it was about trees.. maybe old maples. or seed growing..
