to the Colombian department of Antioquia. It grows in tropical forest and in very wet low mountain forest, in the western cordillera of Jardín, between 1,900 and 2,800m altitude.

Uses

In the past it was probably a very sought-after logged timber species, similar to others species of its family.

Conservation status

''Magnolia jardinensis'' was classified as a critically endangered species (CR) by the Red book of Colombian plants, which is due to its distributional range and because the population is very small.

Flowering and fruiting

The tree has flowers almost the whole year, with a slight decrease of the reproductive output during the month of June. It offers an abundant flowering with floral buds and opened flowers covering more than 20% of the top. Insects pollinate the flowers. The production of fruits is low, which is due to numerous miscarriages during this process. During the rainy season (December to February and August to September) the production of fruits increases.Con base en los informes de trabajo de campo de Suárez, G.A., 2001-2008. Seeds are scattered by birds and small mammals.
