1. DENDROCALAMUS
A genus containing the largest of all bamboo species, forming clumps up to 30m tall. The culms are thin-walled and covered with thick furry wax when young, often with aerial roots at the lower nodes. The branches are usually absent lower down the culm, and are very variable in size, some being more than 5cm in diameter, bearing roots at the base. The inflorescence is spherical, with bracts at its base usually narrow with one ciliate keel (fig. 8), in contrast to those of Bambusa, which are more spicate, with broader bracts that have two ciliate keels (fig. 12).
