Prarie Bowyer, if you can't ID the plant, then you shouldn't eat it. They're probably fine, but on the other hand, they could be the beans of the mysterious willy willy shrub from Timbuktu--the one that makes you foam at the mouth, piss fire, cluck like a chicken and causes your testicles to swell up like balloons. The owners planted it from seed, no doubt, which they received from their world-traveling uncle who happens to be on the US Customs watch list for the illegal importation of willy willy beans. He too has swollen testicles.
