Bambusa alamii (Keng. jacsui, Nep. mugi bans)                                                                   B42

 

This rare species is similar to Chinese Hedge Bamboo, Bambusa multiplex, and is sometimes found near Bhutan's southern border. Like B. multiplex it reaches a maximum diameter of around 4cm and is short for a Bambusa species, with a maximum height of 10m. It has very straight culms with long internodes, and little swelling at the nodes. This species is recognised by its small size, and by its glabrous asymmetrical culm sheaths with large auricles bearing long bristles. The auricles are separated from the culm sheath blade, and one auricle can extend almost

 

halfway down the sheath. The leaves have no hairs, and the culm sheath is firmly attached to the culm below the branch bud. The narrow culms with long straight internodes and small branches are highly suitable for splitting into weaving strips. In the heat of the plains small bamboos from genera such as Drepanostachyum and Himalayacalamus will not grow, and species such as this are a very useful substitute for the smaller hill bamboos. Probably a synonym of B. jaintiana, a species name published with a less than ample description. The types need critical comparison.
