Fraxinus flowers?

Fraxinus flowers?

 

These are galls on male flowers.

Looks like the flowers develop into round fruits so probably a Phellodendron. Otherwise, the first thing I thought of was Tetradium (Euodia).

 

Are the two pics from the same tree?

 

I am not sure if this is the same tree. First picture is taken June 1,second on on May, 31, 2010, both in Ottawa. They could be native, they are from the local river park

 

How I understand it is not ash tree.
More pictures would help?Here are some bark on the pictures.

 

Two different trees, -- Fraxinus and Phellodendron as Ron suggested.

 

Thank you, how I understood, last 2 are Phellodendron and first 3 are Fraxinus

 

Just for the record, it was Michael's suggestion that they were two different trees.

 

Any tree that is an ash will have flowers developing into winged samaras, like those of a maple but not joined at the base into pairs.
