138 TRIANDRIA— D1GYNIA. Festuca. 



through the latter part of summer, and making too conspicuous 

 a figure on lawns about houses. Leaves bright green, short, 

 narrow, smooth ; with long, smooth, striated sheaths. Stipula 

 rather short and abrupt. Spike erect, rigid, linear, green, uni- 

 lateral, about 2 inches long, with a wavy, rough stalk. Anth. 

 prominent, pendulous, purple. Outer valve of the corolla with 

 a short awn. Glumes all permanent, especially the neuter spike- 

 lets. Seed elliptic-oblong, acute, filling the valves of the corolla. 

 A valuable grass in pastures, for sheep and deer, thriving on dry 

 open ground, and, according to Mr. Sinclair, still better in wa- 

 tered meadows. Yet it is certainly not suited to marshy, boggy, 

 or low land. 



2. C. echinatus. Rough Dog's-tail-grass. 



Spike compound, ovate. Neuter spikelets awned. Awns of 

 the corolla full as long as the glume.

Annual. July. 



Root with downy fibres, as usual in grasses inhabiting a loose sand. 

 Stems one or more, smooth, round, leafy, 10 — 20 inches high. 

 Leaves roughish, broad at their base, tapering to a 'sharp point. 

 Sheaths two-edged, swelling, roughish. Stipulas lanceolate, the 

 uppermost longest. Spike dense, various in luxuriance, distin- 

 guished by the elegantly pectinated neuter spikelets at the back, 

 and bristly with the long rough awns of the perfect ones in front. 



The late Mr. Davall suspected the larger-spiked variety, Barrel. 

 Ic. 1. 123./. 2, might be a distinct species. It is the Swiss plant, 

 and approaches C. elegans of Desfontaines, Atlant. v. \. t. \7. 

 Ours has a smaller spike, with much fewer flowers.
