TRIANDRIA— DIGYNIA. Cynosurus. 137 



with the seed, though Schreber's account of its " closely 

 enfolding the seed and not separating," might suggest 

 such 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 

 tlie corolla remains unchanged, and the seed is as little 

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

 whatever. 

 Roots amiual, or perennial. Stems erect, leafy. Spikes dense, 

 simple or compound, assuming a crested appearance from 

 the neuter sjpikelets, mostly concealing the perfect ones.

In dry pastures, parks and lawns, every where. 



Perennial. June, July. 



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

 high, .simple, rigid, round, smooth, most leafy in the lower part ; 

 remaining brown and withered, with their dry empty spikes, 

 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. eclwiatus. Rough Dog's-tail-grass. 



Spike compound, ovate. Neuter spikelets awned. Awns of 

 the corolla full as long as the glume.
