Yushania alpina or African alpine bamboo is a perennial[3] bamboo of the family Poaceae and the genus Yushania[1][4] or the genus Sinarundinaria.[2][5] Not of the genus Chimonocalamus,[6] it can be found growing in dense but not large stands[7] on the mountains and volcanoes surrounding the East African Rift[1] between the altitudes of 2,500 meters (8,200 feet)[7] and 3,300 meters (11,000 feet).[8]

Description[edit]

Stems and leaves
200 - 1,950 centimeters (6 – 64 feet) tall and 5 - 125 centimeters (2 - 50 inches) in diameter;[3] these grass stems get used as fencing,[7] plumbing and other building materials.[9] 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).[10]
