I came across a stand of trees in bloom. At first I thought they might be elder and I'd planned on harvesting some of the blossoms. But when I got closer the leaves were smooth and don't appear to be compound. Here's a photo:
Anybody familiar with this? I'm in Louisiana, and it's growing near the water's edge in a somewhat damp environment, but not in standing water. The flowers are upright and the leaves appear to have smooth margins. They are in an alternate arrangement as close as I can tell (I didn't have a lot of time to examine the tree - incoming thunderstorms).
