Abstract: Restored as a distinct genus in 1961 by Tindale, the fern genus Arachniodes D1. has so far not yet been monographically studied, its exacte rande of distribution and total number of species remaining unknown in the world. From the Asian main-land including Taiwan province of China and Japan the confu-ssed genus has recently been revised by prof. R. C. Ching and the present author and, as a result, there are 116 species, thus constituting a medium--sized genus of the family Dryopteridaceae with Polystichun and Dryopteris being the largest genera each, represented by more than 200 species in the world. Taxonomically, the genus is rather difficult to deal with because great majority of the species are more or less similar in the degree of division of lamina, shape of ultimate pinnules, type of serrature, and form and color of scales on stipe and rachis. The classification scheme proposed in the present paper is based upon about 130 species of the genus from Asia and may serve as well the classification of a few species from extra-asi-atic regions.
