cels 2 to 3 lines long: fruit broadly ovate, hispid, 2 to 3 lines long; 
lateral wings broader than the narrow dorsal and intermediate 
ones. 
An aquatic, first collected in the mountains of N. Nevada, 6,000 feet 
altitude {Watson 456); since collected in S- Utah or N. Arizona {Palmer 183);

flowers; pedicels 2 to 4 lines long: fruit oblong, smooth, 3 or 4
