Abstract
Recent field research on the eastern slopes of the Andes resulted in the discovery of a new species of Bomarea from the Cerro Candelaria Reserve in the Tungurahua province of Ecuador. Bomarea pastazensis is the second smallest species in the genus and differs from the smallest by the presence of glutinous trichomes on the ovary, glabrous sepals, and greenish-yellow petals with purple spots. Based on IUCN guidelines, a preliminary conservation status is assigned as Vulnerable (VU).

Bomarea pastazensis J.L.Clark, Fierro-Minda & N.Exe, sp. nov.
Diagnosis: Similar to Bomarea pumila Griseb. ex Baker, differing in plant height reaching 10–14 cm (vs. 5–8 cm high in B. pumila), pubescent stem (vs. glabrous stem in B. pumila), the presence of ciliate leaf margin (vs. glabrous leaf margin in B. pumila), and the presence of dark spots on the petals (vs. no spotting on the petals in B. pumila).
Etymology: The specific epiphyte, pastazensis, reflects the watershed of the type locality that includes Río Pastaza and adjacent tributaries.

Resumen: Recientes investigaciones de campo en las estribaciones orientales de los Andes dieron como resultado el descubrimiento de una nueva especie de Bomarea en la Reserva Cerro Candelaria en la provincia de Tungurahua en Ecuador. Bomarea pastazensis es la segunda especie más pequeña del género y se diferencia por la presencia de tricomas glutinosos en el ovario, sépalos glabros y pétalos verdes con amarillo y manchas moradas. Con base en los lineamientos de la IUCN, se le asigna un estado preliminar de conservación de Vulnerable (VU).
