15. C. excavata Bdg. Stem branching above the base, 5 to 9 inches high, the 

 branches long and slender ; herbage ascending-hispid, the hairs on the leaves with 

 pustulate bases ; leaf-blades linear, 3 to 9 lines long ; spikes in 2s and 3s, becoming 

 elongated and 1 to 4 inches long, the flowers rather remote; calyx-lobes linear, soft- 

 hairy, furnished with a few slender short bristles, the tips of the lobes spreading; 

 corolla 1 to II/2 lines broad; nutlet 1, borne horizontally, strongly obcompressed 

 and keeled dorsally, ovate-acuminate in side view, obscurely tuberculate on a mi- 

 croscopically papillate-tessellate ground, the ventral groove opening below into 

 a large triangular areola, the areola deeply excavate; fruiting calyx I14 lines long, 

 as broad as long. 



Sandy banks in the hills, 300 to 1000 feet : inner North Coast Range from Yolo 



Co. to Colusa Co. Apr.-May. 



Geog. note. — A species characterized by very remarkable nutlets, both as to structure and as to 

 position in the calyx, Cryptantha excavata is an extremely narrow endemic with a longitudinal 

 range of about twenty-nine miles. Detailed knowledge of its localized occurrence is almost wholly 

 lacking and only three stations are here cited : Cache Creek Caiion, w. Yolo Co., C. F. Balcer 2886 ; 

 e. Lake Co., K. Brandegee ; Sites, w. Colusa Co. The single nutlet is set horizontally in the calyx 

 with the beak pointing outward from the axis and protruding between the two outer calyx lobes.

16. C. recurvata Cov. Stem slender, more or less branched from base, 2 or 

 3 to 9 inches high, appressed-hispid ; leaves with somewhat spreading hairs, the 

 blades linear-oblanceolate, % to % inch long ; spikes in 2s or 3s, bractless, becoming 

 loose ; calyx spreading, in fruit a little recurved, 1 to 1% lines long, the lower half 

 densely bristlj^ with stiff divergent hairs; calyx-lobes linear; corolla minute (V3 

 line broad), scarcely exserted ; nutlet 1, ovate-lanceolate, very finely papillate,
