Amsinckia spectabilis F. & M. 



No. 8153, collected April 11, along the San Joaquin river 

 a short distance above Pollasky, Fresno county, on grassy banks. 

 Plentiful and showy. 



Amsinckia i)ustulata 



Annual, about 3 dm. high, branched from the base, the 

 branches ascending, hispid with scattered white pointed hairs 

 which have oblong pustules at base^ leafy throughout: leaves 

 coriaceous, ovate-lanceolate, the largest lower ones 4 cm. long, 

 i5vnm. wide, the upper reduced but usually broad for their 

 length, rather smooth appearing to the eye, but hispid with 

 sharp white hairs, the pustules at base rounded and raised, very 

 prominent, whitish; inflorescence rather lax, barely i dm. long, 

 naked: flowers bright orange-yellow on pedicels nearly 2 mm. 

 long: calyx 5 mm. long in flower, 8 to 10 mm, long in fruit, the 

 lobes lanceolate, acute, hispid like the leaves but with short vil- 

 lous hairs intermingled, only slightly tawny: corollas small and 

 narrow, exserted about 3 mm. from the calyx: nutlets ovate, 

 short-acuminate, 3 mm. long, nearly 2 mm. wide at base, the 

 back with a raised rib and a slight depression on either side, 

 covered with granulate-warty projections. 



The type is no. 8204, collected May 8, 1906, on the edge of 

 the sand hills about three miles west of Laws, Inyo county, Cal- 

 ifornia. Related to ^. tessellata^ but differing in its broader 

 acute leaves, and less dense pale pubescence. Apparently mixed 

 with that species from the beginning, but its type is the speci- 

 men from near Mt. Diablo, in the coast range.
