Magnolia dixonii (Little 1969: 457) Govaerts in Frodin & Govaerts (1996: 70) has been rediscovered by botanists and conservationists in November, 2017, at the Tesoro Escondido Reserve, a private reserve conserving 2000 ha of primary rainforest in the highly threatened Ecuadorian Chocó, protecting critically endangered species such as the Ecuadorian brown-headed spider monkey (Ateles fusciceps fusciceps). Magnolia dixonii had not been seen in the half a century since its discovery at Hoja Blanca-Gualpi, Esmeraldas Province, northwestern Ecuador.
