Abstract: Dryopteris gemmifera, a new endemic species of Dryopteridaceae from Hainan Island, is described and illustrated. The new species is characterized by its 2-pinnatifid fronds, costae sparsely covered with narrow and flat scales, and especially by the presence of proliferous buds on the distal part of the rachis. The affinity between Dryopteris gemmifera and related species, D. fuscipes and D. guangxiensis, as well as the systematic position of this new species, is briefly discussed. An identification key to all eleven species of Dryopteris from Hainan Island is provided.
