description

Chimonobambusa callosa is persistent and forms leptomorphic rhizomes . The woody stalks grow upright and reach a height of 4 to 7 meters and a diameter of 1.2 to 2.5 centimeters. The internodes are gray, hollow, and 12 to 25 inches long. They are round and smooth. The nodes are thickened and covered with root spines. The straw sheaths are about the same length as the internodes, paper-like and hairy. The tip is clipped, the sides are ciliated. The ligule is 2 millimeters long and frayed. The blade of the blade is linear, 1.2 to 2.5 inches long and hairy down. The leaf sheaths are hairy yellow-brown and downy. The bristles at the end of the vagina (oral setae) are bristly. The ligule is a ciliate membrane. At the base of the leaf blade there is a 0.2 to 0.7 cm long, stalk-like connection to the leaf sheath. The leaf blade is lanceolate or oblong, 20 to 33 centimeters long and 17 to 32 millimeters wide. The midrib is clearly pronounced and ten to 16 pairs of lateral nerves branch off from it. The surface of the blade is rough and hairy, the leaf margins are also rough, the end is pointed. The inflorescences form bracts . The spikelets are sessile, linear and laterally compressed. They are 50 to 75 millimeters long and have no lateral buds. Six to twelve fertile florets are formed per spikelet . Another, reduced and sterile floret is present at the spikelet tip. The internodes of the spikelets are 5 millimeters long, flattened and curved. Two permanent, similar glumes are formed, which are shorter than the spikelet. Both are 6 to 7 millimeters long, membranous, keeled, pointed and one to three-nerved. The lemma of fertile florets is ovate, 5 to 9 millimeters long, membranous, keeled and three to seven-veined. The edges are ciliate, the top is hairy, the end pointed. Three veined and ciliated cavernous bodies , three stamens and two stigmas are formed per flower . The fruits are caryopses with adherent pericarp .

distribution

The natural range of the species is in India.
