 pubescent or glabrate : stem slender, erect or ascending, one-half to two 

 feet high, branching : leaves digitately 3-foliolate ; leaflets cuneate-oblong, 

 obtuse, mucronulate, smooth above, a half to one and a half inches long, 

 exceeding the petioles ; stipules setaceous : peduncles terminal and opposite 

 the leaves, loosely flowered: bracts minute: pedicels recurved: calyx 

 two lines long or less: petals three to six lines long, the keel with a
