Petals at least 10mm long.
It may be hard to see, but I did my best to get pictures of conical protuberances on the achenes.
Growing in a small, partially-shaded depression that becomes inundated with water when it rains enough.

First time finding Robinia! I was very excited to see this. Not sure what variety it is.

This didn't appear planted, but it's by a cemetery, so there's a chance that it's escaped.

There was a small colony of these growing under the trees. Most were not flowering. There were also some especially short plants growing in the same spot with leaves that looked the same as those on the larger plants, but they lacked bristles on the stems. Maybe a separate variety or species? It wasn't flowering, and I didn't get photos of it, but I may return at another date to take a closer look and get some pictures.
