Gastridium. From γaστρiδiov, a little swelling: the glumes are ventricose at the base. A very small grass, formerly referred to Milium. 156. Agrostis. Derived from ἀγρoς, a field. Agrostis was the name given by the Greeks to all grasses.

Richardson; but respecting which the opinion of practical men is still unsettled, and, on the whole, rather unfavorable than otherwise. It seems to suit the climate and soil of Ireland, and to be more productive and nutritive there than any where else. In the account of the Woburn experiments on grasses, it is observed of fiorin, that it appears to possess "merits well worthy of attention, though, perhaps, not so great as has been supposed, if the natural place of its growth and habits be impartially taken into the account." It is called natural place of its growth and habits be impartially taken into the account.' It is called squitch, quick, &c. like the common couch-grass, from the length of time it retains its vital power. Like other plants, which propagate themselves abundantly by extension of their parts, it rarely bears seeds, and is therefore propagated by cuttings of the stems laid along drills an inch deep, and slightly covered with soil.
A. vulgaris, dry arable land is called the black quitch, is the most common and earliest of the bents, but inferior to several in produce, and the quantity of nutritive matter it affords. The bents are generally in produce, and the quantity of nutritive matter it affords. The bents are generally rejected by the agricularis, which in turist on account of their lateness of flowering; but this circumstance, as Sinclair observes (Davy's Agr. Chem.
App. lxxv.) does not always imply a proportional lateness of foliage. A. vulgaris is in leaf by the middle of April. A.s A. stolonifera is two weeks later, and A. nivea, and repens, three weeks later.

Trichodium. Named from θρiξ τρiχoς, hair, on account of its capillary inflorescence. T. decumbens is the famous Agrostis cornucopiæ of Frazer, respecting which so much was said some years ago; but which upon trial did not prove so valuable an agricultural grass as it was represented to be. 158. Tristegis. From τρεiς, three, and σέγη, a covering, on account of the three glumes or valves of the calyx. 159. Sporobolus. From σπoρoς, a seed, and βaλλω, to cast forth. Its grains are loose, and easily fall out of their husks. 160. Airopsis. A word formed by M. Desvaux, from Aira, and oψiς, like. The genus resembles Aira in appearance. 161. Cinna. An ancient name used by Dioscorides, who ascribes heating and stimulating qualities to this grass when eaten by cattle, whence the name (from κεiv, to heat). Linnæus applied it to this genus of American grasses. 162. Psamma. From ψaμμa, sand, in which this grass grows in vast abundance on the sea-coasts of Europe. P. arenarium has a strong creeping perennial root with many tubers at the joints, the size of a pea. It is planted and encouraged on the coast of Norfolk to aid in fixing the sand against the action of the wind and tides, which it effects in a surprising manner. The marrum, as it is called, is considered of so much importance that there are severe laws to prohibit its being destroyed. Mats are made of it, and it is used as thatch. 163. Crypsis. From κρύπτω, to conceal; the heads of flowers being at one time concealed in the sheaths of the leaves. 164. Alopecurus. Alopecurus. Aλωπ Aλωπηξ, a fox, and sea, a tail: fox-tail. A. pratensis is one of the best of meadow-grasses, possessing the three great requisites of quantity, quality, and earliness, in a superior degree to any other. It is 165. PHLEUM.
