VAZQUEZ-GARCIA, José Antonio et al. Magnolia perezfarrerae, a new species and a key to Mexican species of Magnolia (section Talauma, subsection Talauma, Magnoliaceae). Bot. sci [online]. 2013, vol.91, n.4, pp.417-425. ISSN 2007-4476.

A new rainforest species of Magnolia, from the eastern Selva Zoque of Chiapas, Mexico, is described and illustrated. Magnolia perezfarrerae belongs to section Talauma, subsection Talauma. It differs from M. equatorialis in having shorter leaf blades that are elliptic rather than lanceolate, longer petioles, and much shorter apices of the carpels. Unlike any published Mexican species of subsection Talauma, this new species presents a circumcissile dehiscence with abaxial portions of carpels detaching in large irregular and united many-carpelled masses, a trait shared with several Amazonian Magnolia. The flowers are used and valued by the Zoque culture for medicinal purposes.

Palavras-chave : Magnolia equatorialis; Magnolia lacandonica; Magnolia mexicana; Neotropical.
