Abstract

Magnolia lozanoi is rediscovered 26 years after being collected for the first time. Herbarium specimens were collected by Al Gentry in 1993 and formally described by Antonio Vázquez and Ernesto Castro in 2012. This species is known only from El Quimi Biological Reserve in the province of Morona-Santiago, southeastern Ecuador. An emended description, distribution map and the first photographs of this species are provided. Additionally, its relationships with other species are discussed. Its conservation status is proposed as critically endangered (CR) according to IUCN criteria.
