F71FB942FFAAFFBCFF27FED13DC19E4A.taxon	distribution	Distribution and ecology: — Magnolia lacandonica is endemic to the Usumacinta-Lacandonian region of Chiapas in tropical rain forest in the Lacantún and Tulijá basins. It should be looked for in southeastern Tabasco, Mexico, and in the Guatemalan portions of the Usumacinta river basin. No seedlings or saplings were observed, and there was heavy predation on flower buds and immature fruits by squirrels and / or howler monkeys. Cyclocephala sp. (a beetle) chews on flower buds and eats stamens. Magnolia lacandonica is locally rare throughout the Lacandonian rain forest. Eponymy, ethnobotany and conservation: — It is named after the Lacandonian region, where is locally known as “ tajchak ” (Lacandón), “ jolmashté ” (Tzeltal), “ anonillo ”, “ canelo ” o “ magnolia ” (Spanish). Scent of the flowers resembles the smell of guanábana (fruits of Annona muricata L.). The wood of this tree is highly valued by local people, and outside protected areas its occurrence has been drastically reduced due to conversion of rainforest to agriculture and pasturelands. There was a single adult tree at the type locality and two adult trees at the Misolhá waterfall, both under protection. Several trees are protected at the Chajul Tropical Biological Station (UNAM), Montes Azules Biosphere Reserve.	en	Vázquez-García, J.
