TRIANDRIA— DIGYNIA. Cynosurus. 157 



with the seci1<f though Schreber's account of its " closely 

 entolcling the seed and not separating," might suggest 

 iiuch an idea ; for Schrader, so exact in what he observes 

 with his own eyes, does not describe the seed, as seen by 

 himself, in any of his species. In fact, the substance of 

 the corolla remains unchanged, and tlie seed is as little 

 attached to it, in either of our species, as in any grass 

 whatever. 

 Roots annual, or perennial. Stems erect, leafy. Spikes dense, ■ 

 simple or com})oand5 assuming a crested appearance from 

 the neuter spikclcts, mostly concealing the perfect ones.

In dry pastures, parks and lawns^ every where. 



Perennial. June, Juhj. 



Root tufted, with long simple fibres. Stems several, 1 2 — 18 inches 

 high, siiniple, rigid, round, smooth, most leafy in the lower part j 

 remain in?; brown and withered, with their dry empty spikes, 

 through the latter part of summer, and making too conspicuous 

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

 narrow, smooth j with long, smooth, striated sheaths. Slipula 

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

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

 prominent, pendulous, pur])le. Outer valve of the corolla with 

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

 lets. Seed elli])tic-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. cchhialus. Rough Dog's-tail-grass. 



Spike comjiound, ovale. Neuter spikelets awned. Awns of 

 the corolla full as long as the glume.
