Arborescent bamboos, always unarmed, sometimes of very large size. Culms usually 
erect from a densely ramified rootstock. Culm-sheaths deciduous, often very large, 
variably auricled, usually elongate ; imperfect blade narrowly triangular. Leaves shortly 
petiolate, variable in size, sometimes very broad, with no transverse veinlets, but frequently 
with pellucid glands instead. ^ J»flerescence a large compound panicle, the spikelets 
. usually in round congested heads in long spikes. Spikelets ovate, acute or obtuse, 
flowers few, rarely more than six, usually hermaphrodite. Empty glumes 2 to 3, many- 
nerved, ovate, acute or mucronate. Flowering glume similar to empty glume. Palee 
ovate, acute or truncate or emarginate or cleft, those of lower flowers 2-keeled, ciliate, 
those of uppermost flower usually rounded on the back and not ciliate. Lodicules ` none 
or very scarce. Stamens, 6, filaments free; anthers mucronate or with tufted hairs. 
Ovary ovoid, or sub-globular, often depressed, hairy above; style long, usually hairy, base 
persistent ; stigma usually simple. Caryopsis small, the seed surrounded by a crustaceous 
or hardened pericarp, the position of the embryo not usually visible on. the surface. 
 DisrgIB.— Sixteen: species are, so far, known, consisting of the fifteen here described 
and one (2. latiflorus, Munro) found in China and the island of Formosa. Of the Indian 
species, one (D. strictus) is the most widespread and common of all Indian bamboos; 
the rest are confined to the North-East Himalaya, the Indo-Burmese and the Burma- 
Malay regions. D. giganteus is the largest of the Indian bamboos. |
