These species are Athyrium attenuatum (Wallich ex C.B.Clarke) Tagawa, Athyrium flabellulatum (C.B.Clarke) Tardeau-Blot., Athyrium micropterum Fraser-Jenkins, Athyrium rupicola (Edgew. ex Hope) C.Chr., Cystopteris dickeana Sim, Gymnocarpium fedtschenkoanum Pojark, Dryopteris yigongensis Ching, Phegopteris connectilis (Michx.)
