Festuca Earlei Rydb. sp. nov\ 



Perennial with rootstocks and extravaginal innovations ; basal 

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

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

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

 cm. long, I 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 i 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. 



FestJica ornna ingrataYidiCk.; 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. oviua. It is quite dif- 

 ferent from the P^uropean F. oz'iiia 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, i cm. or so long ; ligules O.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 mrn- 

 long, acute; the second 2.5—3 fntri- long, 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 closely related to F. hraclivplivUa, but differs in the 

 smaller spikelets, the more abrupt]}' acuminate flowering glumes, 

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