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]

Systematics[]

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]
