spikelets 4- to 6-flowered; glumes 

 somewhat unequal, lanceolate, 7 to 

 9 mm. long; lemmas firm, rather 

 strongly nerved, scaberulous, acute to 

 cuspidate or short-awned, 7 to 10 

 mm. long. % (F. hallii Piper; F. 

 kingii var. rabiosa (Piper) Hitchc; 

 Hesperochloa kingii var. rabiosa 

 (Piper) Swallen.) — Prairies, hillsides, 

 and open woods, up to about 2,000 

 m. (probably alpine in Colorado), 

 Newfoundland to British Columbia, 

 south to Oregon, North Dakota, and 

 Colorado. Festuca scabrella var. 

 major Vasey. Culms on the average 

 taller; panicle larger and more spread- 

 ing; lemmas more strongly nerved. 

 % (F. campestris Rydb.) — Hills and 

 dry woods, Michigan (Roscommon), 

 Montana to Washington.

 icle, X M; floret X 5. (Rydberg 

 2106, Mont.) 



25. Festuca calif ornica Vasey. Cal- 

 ifornia fescue. (Fig. 67.) Culms 

 tufted, rather stout, 60 to 120 cm. 

 tall; sheaths somewhat scabrous, the 

 collar pubescent or pilose; blades 

 firm, usually involute, sometimes flat, 

 scabrous; panicle open, 10 to 30 cm. 

 long, the rather remote branches 

 usually in pairs, spreading or droop- 

 ing, naked below; spikelets mostly 4- 

 or 5-flowered; glumes somewhat un- 

 equal, 5 to 8 mm. long; lemmas firm, 

 faintly nerved, scaberulous, acumi- 

 nate or short-awned. % (F. aristu- 

 lata Shear.) — Open dry ground, thick- 

 ets and open woods, up to about 

 1,500 m., Oregon and California, west 

 of the Sierra Nevada. A smaller form 

 with pubescent lower sheaths, and 

 shorter, mostly glabrous blades, has 

 been segregated as F. calif ornica var. 

 parishii (Piper) Hitchc. — Oregon and 

 California (San Bernardino Moun- 

 tains) . 



26. Festuca dasyclada Hack, ex 

 Beal. (Fig. 68.) Culms 20 to 40 cm. 

 tall; blades folded, about 2 mm. wide 

 when spread, those of the culm 4 to 

 6 cm. long, those of the innovations 

 10 to 15 cm. long; panicle open, 7 

 to 12 cm. long, the branches rather 

 stiffly and divaricately spreading, 

 softly pubescent ; angles ciliate ; spike- 

 lets pale, long-pediceled, 2-flowered; 

 glumes lanceolate, acuminate, the 

 first about 4 mm., the second about 

 6 mm. long; lemmas rather thin,
