 of the lowest cauline leaves about 12 in. long, those of the uppermost 

 2J to 4 in. long; peduncle glabrous; spike 4 to 6 in. long, slender; 

 rachis slender, continuous; spikelets in pairs, sessile, few-flowered; 

 bracts broad, acuminate-pointed, \ in. long, and \ line wide at the 

 middle, channeled; bractlet 5 lines long, excluding its awn, scabrid; 

 awn 6 to 12 lines long, scabrous, hygroscopic, very divergent when 

 dry, straight and erect when moist; palea 4 to 5 lines long, truncate, 

 scabrous on the margins; achene 3 lines long. 



Type locality: on a dry bank by. the roadside near Petaluma, 

 Sonoma Co., Sept. 18, 1897, Davy, no. 4037; common on dry, brushy 

 hillsides, Point Reyes, July, 1900. 



8. E. angustifolius Davy, sp. nov. Nakkow-lbaved Wild- 

 KYB. Slender, erect perennial, forming low, leafy tufts; rootstock 

 apparently not stoloniferous; stems erect from a more or less arcuate 

 base, IJ to 1\ ft. high, smooth, rooting and branching freely at the 

 lowest nodes; uppermost sheaths glabrous, lowest and those of the 

 branches densely retrorsely scabrous and ciliate on the piargins, or 

 glabrous; ligule I'egularly or somewhat obliquely truncate, \ line long; 

 blades flat, or involute when dry, IJ or rarely 2^- lines wide, sparingly 

 pubescent and scabrid on the upper surface, antrorsely scabrid on the 

 lower, much narrower at the base than the sheath and strongly auri- 

 cled; lowest cauline blades 7 to 8 in. long, uppermost about 4 in. 

 long; spike lanceolate-linear, 2\ to 4J in. long, 3 to 5 lines wide; 

 rachis scabrous on the margins; spikelets in pairs, ascending or 

 appressed, 4J to 7 lines long excluding awns, and slightly exceeding 

 the internodes, 3 to 4-flowered, uppermost flower imperfect or sterile; 

 bracts narrow-lanceolate to linear, acute, 4J to 5 lines long, 3 to 4- 

 nerved and ribbed, scabrid on the nerves; bractlet 4 to 5J lines long 

 excluding the awn, 5-nerved, scabrid; awn erect or somewhat spread- 



■ ing, IJ to 4 lines long, strongly scabrid; palea 4 to 4J lines long, 

 slightly emarginate, ciliate, scabrous on the keels; stamens 3; scales 

 2, I line long, oblique or truncately notched or lobed on one side near 

 the base, obtuse; anthers \\ lines long; ovary clavate; stigmas 1 line 

 long, plumose.— (E. Sibiricus Thurb., in Bot. Cal. in part, not of L.) 

 Common on dry hillsides in the Coast Ranges: San Francisco; 

 Berkeley; Point Isabel. Apr.-June. Near to E. glaueus var. tenuis 

 Vasey, but at once distinguishable by its more tufted and leafy habit, 

 by the usually narrower leaf-blades and by the shorter and relatively 

 stouter spikes.
