Description
Stems and leaves
200 – 1,950 centimeters (6 – 64 feet) tall and 5 – 12.5 centimeters (2 – 5 inches) in diameter;[3] these grass stems get used as fencing,[4] plumbing and other building materials.[6] Culm sheaths (tubular coverings) are hairless or with red bristles.[3]
Leaf sheath is covered with bristles. Leaf blades are "deciduous at the ligule"; blades 5 – 20 centimeters (2 – 8 inches) long.[3]
Flowers
Branched cluster of flowers in solitary spikes, which can be dense or loose and are 5–15 centimeters (2–6 inches) long.[3]
Roots
Short rhizomes described as pachymorph[3] (a term which is recommended for describing rhizomes which are sympodial or superposed in such a way as to imitate a simple axis, but the word pachymorph would not be used for describing branches or in the case of bamboos, culms).[7]
