GRAMINEJE. 



Type locality: Olema, Marin Co., Aug. 1898, Davy, no. 4306b. 

 Near to E. glaucus var. pubescens, differing in the longer and rounded 

 ligule, the hispidulous clothing to the sheaths which is less abundant 

 on the lowest than on those above, and the hispidulous bractlets. 



7. E. divergens Davy, sp. nov. Divergent Wild-rye. Peren- 

 nial; rootstock short, very stout and woody, not stoloniferous; stems 

 stout, erect, 2 to 2\ ft. high; sheaths densely, or the uppermost 

 sparsely, antrorsely pubescent; ligule \ line long, regularly truncate; 

 blades flat or becoming involute, 2\ to 3| lines wide, pubescent on 

 both surfaces or the uppermost glabrous on the lower surface; those 

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

 2\ 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, h 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 Eeyes, July, 1900. 



8. E. angustifolius Davy, sp. nov. Narrow-leaved Wild- 

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

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

 base, \\ to 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 margins, or 

 glabrous; ligule regularly or somewhat obliquely truncate. \ line long; 

 blades flat, or involute when dry, \\ or rarely 2k 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 1 to 4£ in. long, 3 to 5 lines wide; 

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

 appressed, 4 J 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, 4£ to 5 lines long, 3 to 4- 

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

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

 ing, \\ to 4 lines long, strongly scabrid; palea 4 to 4£ lines long, 

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

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

 the base, obtuse; anthers 1} 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 Kanges: San Francisco; 

 Berkeley; Point Isabel. Apr.-June. Near to E. glaucus 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.
