This feature is readily determined by cutting across the shoot with a sharp knife and examining with a pocket lens. The following grasses belong to this group :— Perennial Rye-Grass. 1 Crested Dogstail. The Meadow-Grasses. | Sheep's Fescue. Cocksfoot. I Hard and Red Fescue. I. Base of leaf with claw-llke appendages which clasp the stem more or less (Figs. 186 and 189).. Fig. iI Fig. 190. Perennial Rye-Grass {Lolium perenne L.). This grass is not hairy, and its lower leaf-sheafs just below ground are pink. The ligule is extremely short, and the upper surface of the leaf-blade possesses well-marked longitudinal ribs. The latter are seen best when a leaf is cut across with a sharp knife and the section examined with a lens. 2. Base of leaf without claws (Fig. 190). a.
