History, Use, Propagation, Culture, 
often fit for the scythe by the middle of May ; it flowers twice a-year, and gives more bulk and weight of hay 
than any other grass. At Woburn the produce was nearly three-fourths greater from a clayey loam than from 
a sandy soil, and the grass from the latter was of comparatively less value in the proportion of four to six. 
What is almost peculiar to this grass, Poapratensis and Anthoxanthum odoratum, the value of the grass of the 
latter math considerably exceeds that of the crop at the time of first flowering. A. geniculatus, and most of the 
other species of this genus (A. agrestis excepted) are valuable grasses both for hay and pasture. 
165. Phleum. We have no information as to what the (pXio? of the Greeks was. The name being unoccupied 
has been applied by Linnjeus to this plant. Some think the plant of the ancients was our Typha. P. pratense, 
the timothy-grass (so named from Timothy Hanson, who brought it from New York and Carolina about 1780), 
varies much in size according to soil and situation, and the root becomes bulbous in very dry grounds. Opi- 
nions are different as to its merits. Dr. Walker {Rural Econ. Hebrides, ii. 27.) thinks it may be introduced 
into the Highlands with good effect. W. Salisbury says, it is coarse and late. At Woburn, its " comparative 
merits were considered very great. It produces abundance of fine foliage early in spring, which, as it flowers 
late, may be cropped till an advanced period of the season without injury to the crop of hay." Unlike the 
Alopecurus pratensis, the value of the grass as hay when the seed is ripe is to that when it is in flower as 10 to 
23. P. nodosum has gibbous joints, which might have been expected to be sugary like those of Fiorin, which, 
however, is not the case, as Sir H. Davy found them to be less nutritive than those of P. pratense, in the pro- 
portion of 8 to 28. 
16S. Achnodonton. From ctx^v, a chaff or husk, and o^m, a tooth, in allusion to the toothed paleas or inner 
valves of the flower. 
167. Chilochloa. A genus formed by M. de Beauvois, to contain certain grasses referable to both Phalaris 
and Phleum, as formerly constituted. The name is derived from fodder, and x^ori, grass j but none of 
the species are remarkable for their qualities as grasses useful in husbandry.
