leafy to the summit: leaflets linear-filiform, an inch long, in about 5 pairs: | 
flowers corymbose-cymose: calyx cleft to beyond the middle: corolla half- 
inch broad, white or cream-color: seeds wingless. Collected in eastern 
Washington by Prof. E. W. Hilgard in June 1882.

paniculate inflorescence: leaflets fewer and rather large, membranace- 
ous, only the ultimate at all confluent: style and stamens rather
