Rye Grass
Rye-Grass (Lolium perenne and its variety, L. italicum) is of the most valuable fodder-grasses cultivated in Britain, either in permanent pasture or as a rotation crop. Four crops may be obtained in the year, the first being ready to cut in April, and in sewage-farming the weights of hay which it yields are very great. Its inflorescence consists of a flat compound spike, the spikelets, which overlap, being placed edgeways along the rachis. Each spikelet contains three or more flowers.
