14 species, see text

Isertia is a genus of flowering plants in the family Rubiaceae. It has 14 species, all indigenous to the neotropics. [1] They are shrubs or small trees. A few are cultivated as ornamentals. [2] The type species for the genus is Isertia coccinea. [3]

Isertia was named by Johann von Schreber in 1789. [4] [5] The generic name honors the German botanist and explorer Paul Erdmann Isert. [6]

Isertia is divided into two sections: I. sect. Cassupa and I. sect. 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. [7]

Molecular phylogenetic studies have shown that Isertia is most closely related to Kerianthera, a monospecific genus from Amazonian Brazil. [8]
