Monographs Details: Diodia

Scientific Name:Diodia
Discussion:In the following treatment, which includes the taxa known from Venezuela, the Guayana Highland, the Guianas, and adjacent areas only, the genus Hemidiodia is placed under Diodia. Separation of these genera, based upon the dehiscence of the fruits, appears to be a character of too slight value to be maintained, since a number of species of Diodia show varying degrees of weakness in the septal wall, and the more prominent weakness of the cellular structure of one of the cocci in Hemidiodia apparently represents the extreme of this tendency. This disposition to treat Hemidiodia as synonymous with Diodia has been previously considered by Bremekamp (Rec. Trav. Bot. NĂ©erl. 31: 305. 1934).
