9. CHIMONOBAMBUSA 

 

Spreading, slightly frost-hardy bamboos with well-separated, solitary culms up to 4m tall and up to 2cm in diameter, found in cool broadleaved forest from 1,400m to 2,000m. The culm nodes are raised, with three branches, and often have a ring of prominent thorns. The culms are upright, arising singly from long rhizomes that have roots at all nodes. In growth habit similar to the spreading bamboos of China and Japan in the genus Phyllostachys, and they also have distinct 

 

 

grooving on one side of the culm above the branches. The culm sheath blades are extremely small, and leaf blades have distinct cross-veins. The rhizomes are similar to those of Sarocalamus, but the culm nodes and branching are very diferent. Species of Chimonocalamus, known from China, Meghalaya and Sikkim, also have thorns, but they grow in clumps, with short rhizomes like those of Borinda, and have not been found in Bhutan yet. Shoots arise late in the year.
