Name from Latin cupreus ‘coppery’ referring to the culm sheath cilia.

This bamboo from W Nepal differs from H. falconeri in its erect culm sheath blades, the prominence of the copper-coloured culm sheath cilia, and in its longer culm internodes and culm sheaths.






see origin in Google Earth Himalayacalamus cupreus was introduced into the UK by Merlyn Edwards in 1994 from the Modhi Khola valley in the Annapurna area of W Nepal, where it is harvested for weaving mats and baskets, and for its delicious edible shoots.
