A tree endemic to Ecuador, where it is known from four locales on the eastern slopes of the Andes. One 1938 collection is from Mera; a 1968 collection is from Colonia 24 de Mayo, also in Pastaza province. The Morona-Santiago locale, "Puerto Santana", cannot be located on modern maps. Two collections from 1988 and 1989 are from Sumaco volcano in the Parque Nacional Sumaco-Napo-Galeras. Considered "Rare" by the IUCN in 1997 (Walter and Gillett 1998). The holotype was apparently destroyed in the Berlin herbarium during the Second World War. Apart from habitat destruction, no specific threats are known.
