I've been looking around on the net. I found another site that says G. vesicarium is a synonym for S. vesicaria. The exact opposite of what the other one said. I think this is going to prove to be the correct plant and all I need to do is verify it when I can see it blooming and making pods. The info on this site
http://essmextension.tamu.edu/... really makes me think it's what I have. It confirms a very toxic nature for cattle should they eat the bean. It also lists my specific area in Texas as an area of natural distribution. Good photos that match closely what I've seen as well as good descriptions. I expect the proof will be in the details.
