The leaves of hogla are largely used about Calcutta for thatching temporary sheds. Monoecious, mostly protogynous wind-flowers in capitate or cylindric spikes characterize the Order. Sub-class GlUMIFERjE Nat. Order i. Graminacece.—Herbs, rarely shrubs or trees. Stems (culm) generally fistular, hollow in the internode and solid at the node, frequently strengthened by the deposition of silica (sand) on the outer wall of the epidermal cells. Leaves distichous, sheath forming a tube enclosing the stem but split down the side oppo- site the blade, with a transverse hy- aline or hairy ligule at the apex of the sheath facing the blade. Petiole usually absent, when present very short. Flowers usually 2-sexual, occasionally unisexual and mon- oecious (Maize), arranged in short spikelets which are usually numer- ous and either inserted sessilely on the rachis forming a compound spike, or pediceled, forming a raceme or.
