 1-o-flowered ; bracts like the stipules : calyx |- inch long, the upper 

 teeth united to the middle ; corolla an inch long, dark purple and 

 lilac, the banner finely pubescent: pods glabrous, the valves ecostate, 

 1^ inches long: seeds globose to oblong-cylindric. Rio Blanco; July. 

 (159,) — Much resembling C. Gidanensis, but with elongated petioles 

 and rhachis, the leaflets broader at base, the smaller flowers usually
