A tree endemic to Ecuador, where it is known from seven records in the western foothills of the Andes. Not known to occur inside Ecuador’s protected areas network, but recorded in the Río Guajalito private reserve and the Bosque Protector Mindo-Nambillo. The principal threat is the large-scale deforestation of coastal forests over the last 50 years. The Guayaquil population was last recorded in 1804 by Ruiz and Pavón, but other collections were made elsewhere on the coast in the 1980s and 1990s. Common name: "lengua de vaca". Classified as "Rare" in the Red List of the IUCN in 1997 (Walter and Gillett 1998).
