This is an endemic tree of Antioquia department, where it grows in humid forests in the pre-montane and low montane in a region known as Alto de Ventanas between the municipalities of Briceño, Valdívia and Yarumal. It is a canopy tree and can be found on grazing lands and on the edge of small forest fragments using for protection of water courses. It grows at elevations of 1800 to 2600 m.a.s.l. Uses
This tree is harvested for timber and is used for furniture and wood beams. It is also grown as an ornamental plant. Conservation
This species is listed as Critically Endangered (CR) in the Red Book of Plants of Colombia due to its presence is limited to only one locality smaller than 100 square kilometers. The local habitat is fragmented and degraded, in part by pasture and dairy farming use. Fruit production and seed collection
Magnolia polyhypsophylla produces flower buds year round, but few flowers open or lead to fruit production. Fruit collection should be done during the months of August, September and November, when fruits are most abundant. The fruits take at least 5 months to mature. Fruits are collected before or after they fall from the tree. Immature fruits may be left to ripen so that the seeds may be collected after dehiscence. The fruits are soaked and cleaned to retrieve the seeds. The seeds are sensitive to desiccation. They require no pre-germination treatment and can be sowed in a sand/soil mix. References
