tew, thin, orbicular or rhombic to oblong or broadly spatulate the blade

14-2 inches long: scapose stems numerous, 4-2 inches long: inyolucral 
bracts large, completely united on one edge and little or not at all on the 
other, forming a broad somewhat angular reniform sessile leaf: flowers 
glomerate in the axils of the involucre and not surpassing it; pedicels 
about a line long: calyx orbicular to broadly obovate, a line long, petals 
not seen: seeds small, very black and lustrous, turgid, with a distinct 
white appendage at the hilum. In moist places, valley of the Walla Walla

opposite and distinct: racemes numerous and prolifically flowered, the 
flowers on pedicels 44-34 inch long; petals pink-white, 3 lines long, emar- 
ginate; seeds 44 line long shining and resembling those of C.‘fiberica, but
