Abstract

Four new species of Hymenasplenium (Aspleniaceae) from Africa and Asia are here described based on both morphological and molecular evidence. These four new species include H. guineense and H. kenyense from mainland Africa and H. sabahense and H. wusugongii from Asia. These new species have been erroneously treated as H. unilaterale by earlier pteridologists. The information on their distributions, habitats, and major distinguishing characters of these new species are provided.
