Memecylon plebejum is a tree or shrub species in the Melastomataceae family. It grows in tropical Asia from Thailan to Myanmar, Assam (India) and Bangladesh. It favours slopes of hills and mountains, growing up to 1685m elevation, in the understorey of primary forests primarily. It hosts at least one fruit-fly and two parasitoid wasps. The wood is very hard to cut, making it difficult to use as firewood, but some people use it for agricultural tool handles.
