主　　题：Woodwardia Eocene Climate Hainan Island South China 

摘      要：The genus Woodwardia,which together with the genera Anchistea and Lorinseria comprise the subfamily Woodwardioideae of Blechnaceae,has a disjunct distribution across Central and North America,Europe and the temperate to tropical areas of *** records of Woodwardia occur throughout the Paleogene and Neogene of North America,Europe and ***,well-preserved fertile pinna fossils of this genus have not yet been reported in South *** this paper,a new species,*** Naugolnykh et Song,*** described from the middle Eocene of the Changchang Basin,Hainan Island,South *** and micromorphological features of the fertile pinna show a straight pinna rachis,alternate,subtriangular pinnules,acute pinnule apices,almost entire or slightly undulate pinnule margins,long-ovoid sori,stalked sporangia and spores with wing-like folds on the surface,which are characterised in ***,the present fossil is most similar to the extant species Woodwardia japonica,which mostly grows in warm and moist *** discovery of this new species from the Changchang Basin of Hainan Island indicates that this genus has been distributed in the low-latitude tropical regions of South China from as early as the middle *** on this find,and previous studies of other ferns from the same site,we infer that the climate of the Palaeo-Hainan landscape during deposition of the Changchang Formation was warm and humid,similar to conditions prevailing today across this region.
