G. pilis patentibus partim glandulosis pubescens; foliis trifoliolatis ; folio- 

 lis oblongo-lanceolatis utrinque acutiusculis integerrimis ; sepalis basi 

 connatis lineari-lanceolatis ; petalis (luteis) oblongo-obovatis vix unguicu- 

 latis; sta minibus subwqualibus ; siliquis late oblongis dense pubescenti- 

 bus stipite vix cequalibus stylo longo persistente superatis. 



Hab. Klamet River, Northern California. 



Annual. Stem about a foot high, somewhat branching. Pubes- 

 cence of two kinds; one shorter, grayish, and consisting of simple 

 hairs; the other twice as long, the hairs stouter, yellowish, and partly 

 glandular. Leaves all trifoliolate ; the leaflets 6 to 8 lines long, and 

 pubescent on both sides. Flowers in a terminal raceme which is 

 elongated in fruit. Sepals distinct nearly to the base, tapering to a 

 long subulate point, nearly half the length of the petals, ciliate-serru- 

 late on the margin. Petals about one-third of an inch long, obtuse, 

 furnished with a very short claw. Stamens 6, a little unequal : fila- 

 ments filiform, about twice the length of the petals, smooth: anthers 

 linear-oblong, homomorphous, revolute when dry. Torus very short, 

 bearing a minute fleshy nectary. Ovary supported on a long slender 

 stipe, oblong, densely pubescent, abruptly pointed with a style, which 

 is one-third the length of the ovary itself. Pod three-fourths of an 

 inch long, and about 4 lines broad, compressed, 10-12-seeded, rather 

 obtuse at each end ; the persistent style nearly three lines long ; the 

 valves separating from the filiform placentae. — This is a very distinct 

 species, but allied to G. lutea, from which it differs in its trifoliolate
