Abstract

The genus Diodia s. str. is defined and differentiated from its related genera Borreria G. Mey., Galianthe Griseb. and Spermacoce L. As a result of this study, only 5 American species belong to Diodia: D. virginiana L. (type species of the genus), D. kuntzei K. Schum., D. macrophylla K. Schum., D. saponariifolia (Charn. & Schltdl.) K. Schum. and D. simplex Sw.; all of them are described and illustrated. The remaining species referred to Diodia have been combined into Galianthe Griseb. subg. Ebelia (Rchb.) E. L. Cabral & Bacigalupo or Borreria G. Mey. subg. Dasycephala (DC.) Bacigalupo & E. L. Cabral. D. teres Walt. and its relatives are excluded from Diodia s. str., but their position is still under study.
