This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1901 edition. Excerpt: ...only, and few motor-cells between (Fig. 23). Sclerenchyma at tips of the ridges dense: smaller bands below: strong at margins. Lower cuticle strong. Leaf rolls up. The flat upper leaves oiFeatuca rubra (Fig. 20) and F. heterophylla are somewhat similar in type. They have stiff hairs on the ridges. = = Ridges not more than 2--3 limes as high as the tissue between; each furrow with motor-cells, and each vascular bundle joined to epidermis above and below by a sclerenchyma girder. Brachypodium pinnatum. Smooth. Ridges rounded. Hairs rare. The strong sclerenchyma girders below almost continuous laterally. Epidermal cells with sinuous thick walls, and a few tooth-hairs. Note the differences from B. sylvaticum, p. 76. Melica nutans, M. uniflora, and Calamagrostis Epigeios also come here. (c) (c) Motor-cells confined to the innermost 2--4 furrows. Sclerenchyma in a continuous band just inside the thick cuticle below. Festuca dwiuscula. The ridges are only about half to one-third as high again as the thickness between, and the motor-cells in four series at the base of the three innermost ridges. Each ridge has only one isolated sheathed bundle, without girders. Stomata on the flanks of the ridges, and few in number. The sclerenchyma forms a thick band just inside the strong cuticle below. The leaf is conduplicate, not convolute. This applies particularly to the more open leaves: the subulate leaves belong to the next type (see Fig. 27). Aira canescens and Spartina stricta also come here. Psamma armaria. Inrolled. Smooth below and devoid of keel, with sub-epidermal band of sclerenchyma, and similar tissue at the margin. Ridges of three sizes, the largest twice or three times as high as the leaf-tissue between is thick, all rounded above, and ver
