Trewia is a plant genus of the spurge family (Euphorbiaceae), comprising 2 species. It is found from the Himalaya to Hainan Island. These species have hard large fruits. Trewia species are used as food plants by the larvae of some Lepidoptera species including the leaf-miner Bucculatrix verax, which feeds exclusively on Trewia nudiflora. The hard green fruit of Trewia nudiflora, which fall to the ground in large numbers during the monsoon season, are a preferred food of the Indian rhinoceros. The passage of its seeds through the rhino gut enhances its germination rate. NameThe genus is named after Christoph Jacob Trew (German wiki), a German physician and botanist. Synonyms
