A. verticillata (Type), A. ramosissima.Culmi ramis verticillatis. Flosculi parvi (minus 
quam 4 mm). 
Culms with whorled branches. Florets small (< 4 mm long). 
The epithet is a Latinised diminutive of the Malay word 'bambu', referring to the 
resemblance of plants of the two species to small clumps of bamboo.
