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.[1] A few are cultivated as ornamentals.[2]
Isertia was named by Johann von Schreber in 1789.[3] The generic name honors the German botanist and explorer Paul Erdmann Isert.[4]
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.[5]
Molecular phylogenetic studies have shown that Isertia is most closely related to Kerianthera, a monospecific genus from Amazonian Brazil.[6]
