History, Use, Propagation, Culture, 
154. Folypogon. Named by M. Desfontaines from ^oku, much, and -rooyMv, beard, in allusion to its bearded 
heads. 
155. Gastridium. From ■yMcrri^i^iov, a little swelling : the glumes are ventricose at the base. A vpry small 
grass, formerly referred to Milium. 
156. Agrostis. Derived from ccy^o;, a field. Agrostis was the name given by the Greeks to all grasses. 
Of this genus the most remarkable species is the A. stolonifera or fiorin, so much recommended by Dr. 
Richardson ; but respecting which the opinion of practical men is still unsettled, and, on the whole, rather un- 
favorable 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 squitch, quick, &c. 
like the common couch-grass, from the length of time it retains its vital power. Like other plants, which pro- 
pagate themselves abundantly by extension of their parts, it rarely bears seeds, and is therefore propagated by 
cuttmgs of the stems laid along drills an inch deep, and slightly covered with soil. A. vulgaris, which in 
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 rejected by the agricul- 
turLst on account of their lateness of flowering; but this circumstance, as Sinclair observes [Davy's Agr. Cficm. 
App. Ixxv.) does not always imply a proportional lateness of foliage. A. vulgaris is in leaf by the middle of 
April. A. stolonifera is two weeks later, and A. nivea, and repens, three weeks later. In the south of France 
and Italy, the poor people collect the stolons of different species of agrostis by the roadsides and hedges, and 
expose them for sale in the market places in small bundles, as food for horses.
