. Handbook of grasses, treating of their structure, classification, geographical distribution and uses, also describing the British species and their habitats. Grasses. RIVERSIDES, PONDS AND MARSHES 29 flowering glume. Both these varieties have the flowering glume 3-toothed. Deschampsia caspitosa, the Tufted Hair-grass (fig. 37), luxuriates in wet, spongy soil, and is very common in such places, in meadows and pastures, woods and wayside ditches throughout Britain Easily recognised by its dense tussocks of leaves, 1-3 ft. long, very narrow and tapering finely, dark-green, stiff and excessively scabrid on the upper surface and margins ; the ribs, usually seven in number, are remarkably prominent, opaque, with translucent inter- spaces. Culms 2-4 Panicle large, repeatedly branched, the branches numerous at each insertion and widely spreading. Spike- lets numerous, ^ inch long, silvery-purple, containing two flowers and a rudiment; flowering glumes hairy at the base, with a truncate jagged tip and a very slender slightly curved awn inserted near the base, and scarcely extending beyond the tip. Perennial, flowering middle of July. Phalaris arundinacea, the Reed Canary-grass, is a reedlike species, frequent throughout Britain on the margins of rivers, streams and ponds, and in marshy parts of woods. Root- stock creeping ; leaves large, broadly linear-lanceolate, finely striated; sheaths terete ; ligule rather pro- minent. Culms 4-5 ft. Panicle lax, the branches mostly in pairs, spread- ing at time of flowering. Spikelets rather crowded on the branches to within half an inch of the rachis, J inch long, compressed, pale green, often tinged with rose-purple, i- flowered, with two rudiments (hairy pedicels) beneath the flowering glume ; glumes awnless, the empty ones keeled, the flowering glume polished and ultimately indurated. Perennial, flowering middle of July. The Ribbon-grass commonly grown in gardens is a variety having the leaves striped with white or pale yello
