Oldeania alpina, the African alpine bamboo, is a perennial bamboo of the family Poaceae and the genus Oldeania. It can be found growing in dense but not large stands on the mountains and volcanoes surrounding the East African Rift between 2,500 meters (8,200 feet) and 3,300 meters (11,000 feet) elevation.
Description
Stems and leaves: 200 â 1,950 centimeters (6 â 64 feet) tall and 5 â 12.5 centimeters (2 â 5 inches) in diameter; these grass stems get used as fencing, plumbing and other building materials. Culm sheaths (tubular coverings) are hairless or with red bristles.
Leaf sheath is covered with bristles. Leaf blades are "deciduous at the ligule"; blades 5 â 20 centimeters (2 â 8 inches) long.
Flowers: Branched cluster of flowers in solitary spikes, which can be dense or loose and are 5âÂÂ15 centimeters (2âÂÂ6 inches) long.
Roots: Short rhizomes described as pachymorph (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).
