abstract:Bambusa lako, known as Timor black bamboo, is a large species of bamboo originating from the island of Timor; its black culms may reach 21 m (70 ft) in height. A 2000 molecular study places it as closely related to the similar Indonesian species Gigantochloa atroviolacea, from which it was separated in 1997; it may soon be placed in that genus.
