Upuna

Upuna is a monotypic genus of plants containing the single species Upuna borneensis. The genus name Upana is derived from its Iban name, upan.^[2] The species name borneensis refers to its distribution, being found only in Borneo. It is native to lowland mixed dipterocarp forests up to 400 meters elevation. It is a heavy hardwood similar to Vatica. While Upuna borneensis occurs in protected areas, it is threatened by logging, expansion of palm oil plantations and increasing frequency of fires.^[1]
