In the present paper the genus Christiopteris is emended. The species C. tricuspis and C. sagitta are retained in the genus. C. variant proved to consist of two different species, both originally published as formas. To one of these the rank of species is given, the other one remains as the typical form to C. variant. Furthermore, both species are transferred to the genus Microsorium (Polypodiaceae).
