A variety so little different as scarcelj to deserve thename, but with somewhat broader leaves and more luxuriant habit?of growth, was at one time much celebrated among agriculturists,under the name of Fiorin Grass, or Agrostis stolonifera. It waslunduly lauded, and tlie consequent disappointment led to its beingunduly disparaged. It is a useful grass in moist grounds, newly. reclaimed bogs, or land liable to inundation. The first three orfour joints of the culms lie flat on tlie damp soil, emitting roots inabundance, and it was formerly propagated by chopping these intopieces, and scattering them, but now generally by seed.—HerdGrass [A. dispar) is a native of the United States, with broaderleaves than either of the preceding species, very creeping roots,and large panicles almost level at top. It was at one time stronglyrecommended for cultivation, but has gone out of repute in is, however, more liighly esteemed in France, particularly uponaccount of the great crop which it yields on deep sand and onmoist calcareous soils. — Brown B.
