 to 10 iiK'lies liitrli; herbage {glabrous; leaves very shortly petioled; leaflets linear, 

 Yo to 1 inch lonj;; tlowerinf? raceme dense, its bracts commonly simple, sometimes 

 similar to the leaflets and not reduced, sometimes much reduced; stamens not ex- 

 ceeding the (1 line long) petals; capsule deltoid, 2 lines broad, the valves gibbous 

 or navicular, very bluntly if at all beaked; pedicels 8 to 13 lines long, the stipe l^

 Shumway, Lassen Co., C. C. Bruce 2364a; this appears to be a young state with the leaf bases 

 dccurrent on the stem as very narrow wings; in young specimens of genuine C. parviflora this 

 condition may sometimes be obscurely noted. As to the character, 2 of the stamens "united by 

 the filaments", 2 stamens are often partly united by their filaments in C. parviflora. 



4. C. plocasperma Wats. Stem erect, simple or branching, 5 to 24 inches 

 high; herbage glabrous; leaflets lanceolate or linear, 1/2 to 1^^ inches long, the

 yellow, 2 lines long, exceeded by the stamens; capsule 1 to l^/o lines long, rhomboidal 

 in outline, the valves angular or low-conical; stipe and pedicel about equal, the two 

 together 8 to 10 lines long.
