Dissotis is a genus of plants in the family Melastomataceae.[2] It includes nine species of annual or perennial herbs, shrubs, or small trees which are native to tropical Africa.[1]

Etymology

The generic name is based on the Greek word dissos, which means 'twofold'.[3] This refers to the two types of anthers that is a characteristic of this genus.

Taxonomy

Until recently Dissotis contained dozens of species, organized into four sections – Dissotis, Macrocarpae, Sessilifoliae, and Squamulosae. A 2020 study found that the genus was polyphyletic, and most species formerly placed in Dissotis were placed in five new genera – Almedanthus (for Dissotis pachytricha), Eleotis (for former Dissotis sect. Sessilifoliae), Feliciotis (for former sect. Macrocarpae), Pyrotis (for D. gilgiana) and Rosettea (for former sect. Squamulosae) – or into the existing or revived genera Antherotoma, Derosiphia, and Nerophila.[4]
