Also size of the flower and number per stem wasn't apparent. Butterfly Pea has 5 leaflets but I didn't see all five in the photo. With the Cat's Claw, the woody stems looked like a tree or bush rather than a vine. Mesquites have similar looking leaves and flowers.
According to my "Wildflowers of Arkansas" book by Carl G Hunter, Butterfly Pea leaves are trifoliate. Thanks again for your help Mitch! You are the man!
