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 V\ázquez 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.

Se describen dos nuevas especies de Magnolia del norte de la serran\ía de los Yarigu\íes, Santander, Colombia: Magnolia resupinatifolia y Magnolia betuliensis. La primera corresponde a la secci\ón Talauma, subsecci\ón Talauma y morfol\ógicamente se asemeja a M. sambuensis, de la que se distingue por la yema foliar con indumento ser\íceo color cobrizo claro, flores con tres br\ácteas amplectantes, p\étalos m\ás peque\ños, frutos maduros esferoides, eje del fruto obovoide a esferoide, y carpelos en frutos con la pared externa convexa. La segunda especie se asocia a la secci\ón Talauma, subsecci\ón Dugandiodendron, y difiere de M. coronata y M. yarumalensis, principalmente por tener pec\íolos de mayor longitud, y menor n\úmero de estambres y carpelos. Se excluye para la flora de Colombia a M. chimantensis, originaria del cerro Chimant\á en el sureste de Venezuela, la cual fue registrada para el pa\ís con base en la identificaci\ón err\ónea de material est\éril correspondiente a M. betuliensis.
