Bambusa longispiculata, or Mahal bamboo, is a species of clumping bamboo native to Bangladesh and Myanmar, but widely grown in many other countries including Australia. Growing in wide and open clumps, it makes an excellent shelter for waterfowl. It is not suited for harvesting and is very suitable for soil stabilization on dam faces. It can grow up to a height of 10 m, and a thickness of 5 cm.

Bambusa longispiculata est species Bambusearum familiae Poacearum, in Australia endemica. Latos apertosque fasciculos faciens, tutum avium aquaticarum perfugium fit. Stabilitatem soli in faciebus molium adiuvare potest. Ad altitudinem 10 metrorum et ad crassitudinem 5 centimetrorum crescere potest.
