The specific epithet ("angustisepala") was derived from the Latin words meaning "narrow" and meaning "sepal", referring to the narrow sepals of this species. Distribution and habitat. This boronia grows in forest on sandstone or granite and is found in the Gibraltar Range National Park and the Bylong-Sandy Hollow-Denman area.
