摘要
A new species of Cipoia (Podostemaceae) from the state of Minas Gerais (Brazil) is described and illustrated: Cipoia ramosa. It is distinguished from the only other species in the genus, C. inserta, by its branched stems, stipules composed of two tooth-shaped appendages adjacent to the leaf base, anther thecae that remain at a prominent angle during and after anthesis, and an ovary that is longer than the stigmas at anthesis.
