A tree endemic to eastern Ecuador. Considered an uncertain taxon in the Flora of Ecuador, because the original material was destroyed in the Berlin herbarium during the Second World War and few collections exist. It seems likely that the consistent differences in flower size and number of flowers observed in existing specimens will confirm this species as valid, but more collections and field observations are needed. Only one small population has been recorded, in secondary forests of southwestern Pastaza province. Apart from habitat destruction, no specific threats are known.
