I am convinced it is not the coral bean (Erythrina crista-galli). The leaves on this are hairy, not a soft hairy but very, very short hairy that makes it rough to the touch as if your clothing dragging across it would catch. My first thought when I saw it was that it was in the trefiol - Desmodium although I have never seen one so large leaved before & it's much lighter green in leaf color. I'm going to watch for the blooms plus I need to check out the stems more closely now that I have more idea what to look for. Thanks Jay & Greene!
Sorry Stone, if it's indeed Desmodium, I will pull them. Believe me, there is plenty enough Desmodium of the smaller varieties on this property for the wildlife. So much so that I fight to keep from being overrun with it.
I will not mark this solved yet until I am positive about it. Soon enough, I will know.
