Question
I have these growing in my yard this year. The largest one attracts a lot of ants. I included a picture of one feeding on what seems to be an extra-floral nectary. The stem has spines at the nodes. The leaves have an even number of leaflets -- a pair at the tip.
Answer
Dear jfc, good morning. You have photographed a species of Chamaecrista (sensitive-pea), in the Fabaceae. I can't see the extra-floral nectary well because of the position of the ant, but I think you likely have Chamaecrista fasciculata (partridge sensitive-pea). Best wishes.
