Torr. Club 14: 133. 1887. Culms ii°-4° tall, erect from a long horizontal rootstock, simple, smooth and glabrous. Sheaths smooth, the lower short and overlapping, often crowded, the upper much longer; ligule a ring of short hairs; blades i°-2° long, i"-2" wide, invo- lute ; panicle ample and diffuse, 8-22' in length, the branches finally widely spreading, fiexuous, the lower 3'-8' long; spikelets about 3" long, 1-3-flow- ered, the empty scales acute, glabrous; flowering scales with a ring of hairs at the base, minutely scabrous, twice the length of the empty ones, acute, the middle nerve usually excurrent as a short point.

Tufted grasses/ with narrow flat leaf-blades and long slender spikes arranged in an open panicle, or rarely only one terminal spike. Spikelets several-flowered, narrow, sessile or shortly pedicelled, erect. Two lower scales empty, membranous, keeled, acute, unequal; flowering scales 1-3-nerved, 2-toothed and mucronate or short-awned between the teeth. Palet hyaline, 2-nerved. Stamens 3. Styles distinct. Stigmas plumose. Grain free, loosely enclosed in the scale and palet. [Greek, referring to the 2-toothed flowering scales.] About 15 species, natives of the warmer regions of both hemispheres. Besides the following species, about 6 others occur in the southern and western parts of North America. Type species: Festuca fascicularis Lam. Awn less than ^ as long as the flowering scale. Spik
