Abstract: In the present paper several species of Lycopodium L. from Sichuan, West China, are enumerated, of which 4 are described as new. They are: L. emeiense Ching et H. S. Kung, L. nanchuanense Ching et H. S. Kung, L. crispatum Ching and L. kangdingense Ching. In the course of this study, the writer has tried as much as he could to review rather exhaustively all the Lycopodium species of the province published sporadically in the literature in the past and their identity is established on the basis of rich materials available, thus a number of mistakes by earlier authors being revised. My thanks are due to the comrades of herbaria of many botanical institutions and universities for their friendly co-operation, and to Prof. R. C. Ching of the Instituteof Botany, Academia Sinica, under whose guidance the present study was carried out.
