Found this plant growing under a canopy of oak trees
Hi Gail,
all I can tell you for sure is that this is a Desmodium, but I am not sure of the species. Clearer photos and fruits are needed for a specific identification. They are called tick-trefoil or beggar lice, and it is a native plant.
Sincerely,
