'''''Upuna''''' is a monotypic genus of plants containing the single species '''''Upuna borneensis'''''. The genus name ''Upana'' is derived from its [Iban](/source/Iban_language) name, upan.<ref name = Ashton/> The species name ''borneensis'' refers to its distribution, being found only in [Borneo](/source/Borneo). It is native to [lowland mixed dipterocarp forests](/source/Borneo_lowland_rain_forests) up to 400 meters elevation. It is a heavy hardwood similar to ''[Vatica](/source/Vatica)''. While ''Upuna borneensis'' occurs in protected areas, it is threatened by logging, expansion of [palm oil](/source/palm_oil) plantations and increasing frequency of fires.<ref name="iucn status 16 November 2021" />
