I recently took a walk through the wood of east texas and found a strange tree resembleing acacia family, it always seems to grow near streams almost in the stream with shade cover. it has a wonderful smelling flower when the pistils come out( the flowers without pistils don't smell) it leaves are broad unlike the mimosa family.

yes its a sample i brought back

Im not 100% sure, but according to that site I gave you it looks like Acacia AKA Catclaw. So you may be inluck, but I'd be doubly sure if I were you.

didn't realize the link oops . /: But no the leaves were long and narrow unlike that of a mimosa family still stumped on this one no web resources are showing it ):
