Macaranga

(Genus)

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, Asia and the South Pacific, the genus comprises over 300 different species. These plants are noted for being recolonizers, that is, they are among the first plants to appear on disturbed ground.

Macaranga species are used as food plants by the larvae of some Lepidoptera species including Endoclita malabaricus.

Macaranga are morphologically adapted with thin stem walls to create domatia (housing) for an ant species from the genus Crematogaster, who in turn protects its plant against herbivores. [1]

Use

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