This post is the latest in the series Uncover Diverse Colombia by Colombia Photo Expeditions, in which Kike Calvo profiles interesting information, research and thoughts on Colombia for journalism, ecotourism, science, exploration and photography.

A new journal article in Caldasia about the pollen of Colombian magnolias by Marcela Serna-González and César Velásquez-Ruiz was recently published by the Instituto de Ciencias Naturales, Universidad Nacional de Colombia.

The articles unveils how Colombia, with 36 species, has the highest number of species of the family Magnoliaceae  in South America. In spite of the family’s evolutionary importance and significant threats to species survival, information is still lacking about Colombian Magnoliaceae due to a paucity of research. In this article, the pollen morphology of fourteen Magnolia species from Colombia is described based on size, shape, apertures, exine and sculpture.

The high uniformity of pollen morphology among the Colombian species supports the most recent classification of the American magnolias.
