A new species of Campsiandra (Caesalpinieae) from the Lower Rio Napo and Rio Nanay of Peruvian Amazonia is described and illustrated. Campsiandra cowaniana resembles C. angustifolia in the size and general characteristics of the flower and chartaceous leaflets, and C. steyermarkiana and C. robclarkiana by the tortuous stamens. However, it is distinguished from all other species of the genus by the large, chartaceous but glabrous, nitid, obovoid-lanceolate leaflets and one of the 5 petals rotate.
