Oldeania alpina explained

Oldeania alpina, the African alpine bamboo, is a perennial[1] bamboo of the family Poaceae and the genus Oldeania. It can be found growing in dense but not large stands[2] on the mountains and volcanoes surrounding the East African Rift between 2,500 meters (8,200 feet)[2] and 3,300 meters (11,000 feet) elevation.[3]

Description

Stems and leaves: 200 – 1,950 centimeters (6 – 64 feet) tall and 5 – 12.5 centimeters (2 – 5 inches) in diameter;[1] these grass stems get used as fencing,[2] plumbing and other building materials.[4] Culm sheaths (tubular coverings) are hairless or with red bristles.[1]
  • Leaf sheath is covered with bristles. Leaf blades are "deciduous at the ligule"; blades 5 – 20 centimeters (2 – 8 inches) long.[1]
    Flowers: Branched cluster of flowers in solitary spikes, which can be dense or loose and are 5–15 centimeters (2–6 inches) long.[1]
  • Roots: Short rhizomes described as pachymorph[1] (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).[5]
