Chimonobambusa is a genus from the Arundinarieae tribe of woody bamboo - species of temperate climates . The range of the species is in East Asia.

description

The species of the genus grow persistently , bush-like, more rarely almost tree-like. The rhizomes are leptomorphic . The woody stalks usually grow scattered and sometimes form tufts. They stand upright and are 60 to 1400 centimeters long. The internodes are round or square and often form a groove ("sulcus") at the base over the branches. The nodes are thickened to severely thickened. Nodes near the base of the stalk often form a sparsely to densely thorny ring made up of roots. A part of the straw sheath can remain at the base of the knot or a hairy ring can form at the scar. The buds at the nodes are egg-shaped-triangular and have only a reduced cover leaf . Usually three side branches are formed per node in the middle of the stalk, and up to seven side branches of approximately the same thickness towards the tip of the stalk. The straw sheaths are leathery and soon fall off, they are less often membranous and permanent. The straw leaf tubes are very small or missing. The blade blade is up to 1 centimeter long and narrow. Seldom only one, usually two to five leaves are formed per branch. The leaf blade is lanceolate, the base wedge-shaped.

The inflorescences show bracts and one to three spikelets, i.e. spikelets with basal buds that can form further spikelets. A few to many sessile flowers are formed per spikelet. The usually one to three glumes are shorter than the spikelet, with one often at the base of a bud. The lemma is membranous, membranous, doubly keeled and obtuse. Three membranous cavernous bodies and three stamens with free-standing stamens are formed per flower . The ovary is ellipsoidal and wearing a short pen with two or three feathered scars . The fruits are nutty caryopses with a hardened pericarp .

Young shoots grow from April to November.
