The proportion of such attached seeds is especially high in immature samples. Usually only the lowest pair of paleee contain a grain. Dactylis glomerata, L. (Cocks-foot.) (Fig. 87.) See p. 145. A coarsely-tufted perennial growing on almost every type ofsoil. The plant is entirely glabrous though it may often be roughto the touch. Its foliage is dull and varies much in colour—from alight green to a deep bluish-green

The proportion of such attached seeds is especially high in immature samples. Usually only the lowest pair of paleee contain a grain. Dactylis glomerata, L. (Cocks-foot.) (Fig. 87.) See p. 145. A coarsely-tufted perennial growing on almost every type ofsoil. The plant is entirely glabrous though it may often be roughto the touch. Its foliage is dull and varies much in colour—from alight green to a deep bluish-green hue. Sheaths entire, very sharplykeeled both at back and front. Leaves folded in the flattenedshoots; blade partly conduplicate, long, and tapering into an acute 94 Botanical Section [PT I apex; its edges finely serrated, ribless above, and strongly keeledthroughout its length below. Ligule long, white, and absent. Abundant throughout Fig. 90. Two aquatic grasses. Glycerin aquatica, Shi.(left). Digraphis arundinacea, Trin. (right).About J nat. size. Fig. 01. Two sea-coastgrasses, a. Spike of Ely-iints arenarius. b. Spike-like inflorescence ofPsamma arenaria. About\ nat. size. Flowers late in May or early in June. Culms from two tothree feet high, the upper sheaths and blades of the culm veryharsh to the touch. The panicle consists of clusters of spikeletsarranged on contracted or shortened branches, thus giving it aclose, dense, heavy appearance. Spikelets three to five flowered. ch. vn] Botanical Description of Species 95 Glumes nearly equal, strongly keeled and pointed, with scariousmargins; the lower one distinctly hairy on the keel, andto a lesser extent on the margins; the upper glume lesshairy. Seed. Outer palea of a light straw colour, varying from4 to 9 mm. in length (usual length 5-6 mm.), terminating in acurved point sometimes one-third the length of the palea. Theupper part of the keel of the outer palea
