Abstract:

 The Chinese species of Selaginella subgenus Tetragonostachys are revised. Three spe-
cies are distinguished in the present study, i.e.S. sibirica, S. indica and S. vardei. Illustra-
tions of the leaves and strobili, distribution maps of the subgenus and the species occurring in China
are made to facilitate easy identification of the species. The distribution of the species in China
shows an interesting southwestern China and northeastern China distribution pattern.

Key words: Selaginellaceae, Selaginella subgenus Tetragonostachys, China, Distribution andecology
