Festuca ovina, L., var. Tenurrot1a—South Park, Colorado, 1873 
(1151). 
Festuca ovina, L., var. BREVIFOLIA, Watson.—Mount Lincoln, Colorado, 
1873 (1152). 
Festuca TeNeLLA, Willd—Denver, Colorado, 1873 (1147); Santa

Festuca Tuursert,* Vasey.—Culm 2-24 feet high, erect, czespitose, 
smooth, 2—4-leaved; leaves rigid, involute, 6’ long, scabrous ; radical leaves 
numerous, involute, rigid, 1-14° long, very scabrous on the margin, sheaths 
somewhat membranaceous; blade deciduous when old; panicle compound, 
3-5’ long, a little drooping, of 4-5 nodes; branches or rays single or in 
pairs, slender, 2-4’ long, spreading when ripe, branching at or below the 
middle; spikelets purplish, oblong-lanceolate or cylindrical when young, 
broad above when expanded, 3-5-flowered, 5-6” long, slightly scabrous 
under the lens; glumes thin, membranaceous, $ shorter than the flowers, of 
nearly equal length (2”), obtuse or acutish, upper one convex, not com- 
pressed, obscurely nerved, lower one slightly keeled; flowers cylindrical, 
convex, not compressed; outer palet obscurely 5-nerved, 3” long, lanceo- 
late, acute or short cuspidate, minutely scabrous; inner palet narrow, 
slightly hispid on the keels, equalling the outer, sometimes bifid at the apex. 
This species in several preceding collections from the Rocky Mount- 
ains has been called Festuca scabrella, Torr., but upon careful comparison 
of the figure and description of that species in Hooker’s Fl. Bor. Am., I am 
satisfied that this is a different species —Twin Lakes, Colorado, 1873 
(1153); South Park, Colorado (1154)—Piare XXIX. Natural size.
