BAMBOOS OF INDI A

Dendrocalamus
sometimes very small on one side; blade 25-40 cm long and 2.5-3.5 cm broad, lanceolate-acuminate, recurved. Young
shoots spear-shaped. Leaves 10-30 cm long and 2.5-4.5 cm broad, oblong-lanceolate to linear-lanceolate, acuminate,
short-stalked margins rough; leaf-sheath ligulate, covered with brown pubescence, margin ciliate. Inflorescence a large
panicle of interruptedly spicate clusters of spikelets, sometimes leafy rachis flexuose, flattened on alternate sides 1.3-3.8
cm between clusters, glaucous-green, sometimes rough. Spikelets in heads, sometimes few-flowered blunt, nearly glabrous,
5-7.5 mm long; empty glumes 2-3, obovate, blunt, with short rachillae between; flowers 2-3 fertile; flowering glume
blunt, obovate, cucullate, ciliate on the edges, many-nerved; palea oval, truncate, faintly keeled, 2-nerved between the
keels, faintly pubescent. Stamens short; anther yellow, short, ending in a black mucronate point; filaments short. Ovary
broadly ovoid, somewhat acute, hairy, ending in a rather short style and short purple stigma. Caryopsis ovoid,
somewhat oblique, yellow,
surmounted by a beak
formed by the base of the
style.
The distinguishing vegetative
features are long
papery culm-sheath with
depressed sinuous top covering
almost the whole internode
and the young
shoot with reflexed blades.
