Common Name : Hedge Bamboo, Chinese Bamboo

They occur as loose clumps and are not perennial. The rhizomes are short and pachymorph type. The culms are erect growing from 200–400cm in length and 10–30mm in diameter. They are without nodal roots. The culm-internodes are cylindrical, medium green, hollow and are smooth distally. The lateral branches display a tree like appearance. The bud complement is one, the branch complement is three or many and they are in a clump, there is one dominant branch and thinner than stem. The culm-sheaths are deciduous with hairs on the shoulders and sharp at the tip. The culm-sheath ligule is 1–1.5mm in height. The culm sheath blade is acute, 1–2cm in length with 7–13 leaves per branch. The leaf-sheath oral hairs are covered with thick hairs and are 3–5mm in length. The leaf-sheath tips are sickle-shaped. The ligule is an enciliate membrane. The collar has an external ligule, the leaf-blade has a petiole-like connection to the sheath and the petiole has 0.1–0.2cm in length. The leaf blades are deciduous at the ligule, 7–10cm in length, 10–13mm in width, dark green in colour and having a frosted look with discoloration on the last colour beneath. The leaf blade surface is hairy abaxially and puberulous and is sharp at the tip. The synflorescence is bractiferous, at the nodes clustered, lax and in untidy tufts, with subtending spathaceous bracts, leafless between clusters, below the lateral spikelets prophyllate, at the base of the spikelet with axillary buds. Fertile Spikelets: Laterally compressed, lanceolate, 30–40mm in length, at maturity they break-up, disarticulate below each fertile floret. Internodes of rachilla are definite. There are seven to 10 fertile florets which comprise the spikelet and florets are diminished at the apex. Florets: Without keel, 15mm in length, veins-20 in number, fertile lemma is lanceolate. Apex of lemma is acute. Palea keels ciliate and winged, palea oblong and 1 length of lemma. Apical florets are sterile though they resemble fertile florets and are underdeveloped. Flower: Lodicules membranous and three; Anthers 6mm in length and six in number; Ovary pubescent at apex and umbonate. Fruit: Caryopsis. Pericarp adherent.
