UPLANDS, HEATHS AND MOORS 25 land ; it is distributed all over Britain. Rootstock tufted ; leaves flat, firm, rather short, tapering above, with scarcely perceptible ribs, rough margins, dull glaucous green ; ligule short and trun- cate. Culms about a foot high. Panicle deltoid or pyramidal, lax, vifith capillary spreading branches. Spikelets pendent, i to j inch long, subtriangular, or broadly ovate and compressed, tinged with brown or purple, 6- or 7-flowered ; glumes very closely im- bricate, broad, deeply concave or saccate, rounded on the back, obtuse at the tip, and awnless ; empty glumes smaller than the lowest flowering ones. Perennial, flowering middle of June, July. Deschampsia flexiiosa, the Wavy Hair-grass, is generally distri- buted throughout Britain on dry heaths and in upland pastures and copses, always growing in abun- dance. Rootstock rather densely tufted, producing numerous leaves, which are setaceous and solid, usually curved, smooth, dark-green. Culms IJ ft., reddish-purple. Panicle with slender, spreading, wavy branches, which are mostly in pairs and triply- forked. Spikelets \ inch long, pur- plish-brown and glossy, 2-flowered ; flowering glumes with a tuft of hairs at the base, a truncate and toothed or jagged tip, and a bent and twisted awn inserted near the base, and ex- ceeding their length by one half. Perennial, flowering in July. Triodia decumbens, the Decumbent Heath-grass, is found in the same habitats as and is widely distributed, though not very common. Rootstock tufted, rather stout, de- cumbent and compressed. Leaves narrow, stiff, and often involute, glaucous above ; sheaths hairy ; ligule, a ring of hairs. Culms about a fcit high. The panicle rarely bears more than 5 or 6 spikelets, which are shortly pedicelled, about \ inch long, green, tinged with v
