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

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

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

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

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

 shorter, the panicles narrower and few-flowered, the spikclets 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).
