9. S. eminens Cav. Culms slender, puberulent below the nodes, 2 to 3 feet 

 high; sheaths smooth, sparingly villous at throat; ligule very short; blades 

 flat, narrow, 1 to 2 lines wide, pubescent on upper surface near base; panicle 

 rather loose and open, usually 6 to 8 inches long, but sometimes more than 1 

 foot long, the branches distant, slender; glumes 3-nerved, smooth, unequal, 

 acuminate, the first 3 to 5 lines long, the second about 1 line shorter; lemma 

 about 3 lines long, sparingly villous, nearly glabrous toward the hairy-tufted 

 apex; awn indistinctly twice-geniculate, about 1 to V/ 2 inches long, scabrous 

 but not villous. 



Coast Ranges from Berkeley Hills (Davy 4235) to San Diego (Orcutt 1065), 

 east to San Bernardino (Parish 2055) ; south into Lower California and east to 

 Texas and Mexico. 



Var. andersoni Vasey. Differs from S. eminens chiefly in the slender invo- 

 lute blades. This form is, on the average, a smaller plant, the culms being 

 shorter, the panicles narrower and few-flowered, the spikelets usually smaller. 

 Confined to California, where the range is about the same as that of S. eminens 

 but extending north to Mt. Shasta (Jepson in 1895).
