Isertia
Genus of shrubs
Isertia is a genus of flowering plants in the family Rubiaceae. It contains 15 species of shrubs or small trees that are indigenous to the neotropics. A few are cultivated as ornamentals.
01Systematics
Isertia was named by Johann von Schreber in 1789. The generic name honors the German botanist and explorer Paul Erdmann Isert.
Isertia is divided into two sections: section Cassupa and section Isertia. In section Cassupa, the fruit is a berry and the ovary usually has two or three locules. In section Isertia, the fruit is a pyrene and the ovary usually has five or six locules.
Molecular phylogenetic studies have shown that Isertia is most closely related to Kerianthera, a monospecific genus from Amazonian Brazil.
