Festuca Earlei Rydb. sp. nov. 



Perennial with rootstocks and extravaginal innovations ; basal 

 leaves with short ligules ; blades filiform, 5—10 cm. long, strongly 

 involute, 0.5 ram. wide or less; sheaths of the culm-leaves 3-5 

 cm. long, striate, smooth ; ligules very short, truncate ; blades 3-5 

 cm. long, 1 mm. wide or less ; culm about 3 dm. high, very 

 slender ; panicle narrow and spike-like, 3—5 cm. long ; branches 

 short and erect, smooth ; spikelets 2— 3-flowered, about 5 mm. 

 long; first empty glume about 2 mm. long, narrowly lanceolate; 

 the second about 3 mm. long, ovate-lanceolate, 3-nerved ; flower- 

 ing glumes narrowly lanceolate, about 4 mm. long, smooth, usually 

 awned ; awn 1 mm. or less long. 



This species is related to F. rubra, but differs in the smaller 

 few-flowered spikelets, the smaller flowering glumes, and the fine, 

 soft leaves.

Festuca ingrata (Hack.) Rydb. 



Festuca ovina ingrata Hack. ; Beal, Grasses N.Am. 2 : 598. 1896. 

 This is the common plant of the Rocky Mountain region, 

 which has been known under the name F. ovina. It is quite dif- 

 ferent from the European F. ovina L. The latter is found in 

 America only in the northeastern part of the continent. 



Festuca minutiflora Rydb. sp. nov. 



Tufted perennial with intravaginal innovations ; leaves mostly 

 basal ; sheaths smooth, 1 cm. or so long ; ligules 0.75 mm. long, 

 obtuse or rounded at the apex ; blades 5—10 cm. long, narrow and 

 flaccid, about 0.5 mm. wide; sheaths of the culm-leaves 2-4 cm. 

 long; blades 1—3 cm. long; culm very slender, t— 1.5 (seldom 3) 

 dm. high ; panicle very narrow, lax, 2—4 cm. long, with very short 

 erect branches ; spikelets, excluding the awns, about 5 mm. long, 

 2-3-flowered ; first empty glume narrowly lanceolate, 2—2.5 mm. 

 long, acute; the second 2.5-3 mm. l° n g. ovate-lanceolate, .short- 

 acuminate or awn-pointed; flowering glume oblong-lanceolate, 

 about 2 mm. long, purple-tinged above, abruptly contracted into a 

 short awn, 1.5 mm. or less. 



This is closeK' related to F. brachyphylla, but differs in the 

 smaller spikelets, the more abruptly acuminate flowering glumes, 

 the shorter awns, the laxer panicle and the soft filiform leaves. It
