Thank you, UrsulaGelchsheimer. I believe you've got it. From what I read, the seed pods start out yellow, turn green, then brown. It is an invasive species, toxic to birds and mammals. I'm surprised the park service doesn't get rid of these before they become more of a problem.

compare with Sesbania punicea
no, that's just where the leaf stems are coming off the branches
Are those thorns on the plant?
