Macaranga is a large genus of Old World tropical trees of the family Euphorbiaceae and the only genus in the subtribe Macaranginae. Native to Africa, Australasia, Asia and various islands of the Indian and Pacific Oceans, the genus comprises over 300 different species.[4][5] It was first described as a genus in 1806, based on specimens collected on the Island of Mauritius.[1][3]

Macaranga is noted for being recolonizers. Macaranga species are used as food plants by the larvae of some Lepidoptera species including Endoclita malabaricus. Macaranga species often form symbioses with ant (Formicidae) species (particularly Crematogaster ants of the subgenus Decacrema) because they have hollow stems that can serve as nesting space and occasionally provide nectar. The trees benefit because the ants attack herbivorous insects and either drive them away or feed on them.[6]

Use[edit]

Macaranga Gum, a crimson resin is obtained from Macaranga indica.
