description

Chimonobambusa angustifolia is perennial and forms leptomorphic rhizomes . The woody stalks reach a height of 2 to 5 meters and a diameter of 1 to 2.5 centimeters. The internodes are green and 10 to 15 inches long. They are slightly square in cross-section or with round terete, warty, initially densely white-downy and sparsely hairy with bristles. The nodes are purple in color and clearly thickened. At the vaginal scar under the knot there is usually a ring of nut-brown eyelashes or the base of the straw sheath. The knot at the base of the stalk shows a ring of nine to fourteen thorn-like roots. Three side branches are formed horizontally to each other for each bud. The straw sheaths are reddish-yellow, shorter than the internodes and crisscrossed by clearly raised, purple-colored leaf veins. The ligule is truncated or arched and finely ciliate. The blade blade is sub-triangular and 3 to 5 millimeters long. One to three, rarely four leaves are formed per end branch. The leaf sheaths are bare or initially ciliate. At the transition to the leaf blades there are three to five straight, pale bristles 3 to 5 millimeters long (oral setae). The ligule are small and arched. The leaf blade is linear-lanceolate to linear, 6 to 15 centimeters long and 0.5 to 1.2 centimeters wide, paper-like and hairless. Three to four pairs of nerves are formed per leaf. Inflorescences are unknown. New shoots grow from August to September.
