Though the fern and fern allies in N. E. China have already beenstudied by the botanists came from Russia, Japan as well as China overand over again, but there are still some questionabal problems which havenot got satisfactory solution at present. After studied all the species sofar reported, some confution in nomenclature have been found. The presentpaper has shown the result. Lycopodiaceae: 1) There are neither ture Lycopodium clavatum L. norL. clavatum L. var. nipponicum Nakai in N. E. China. The plant whichgenerally considered as L. clavatum L. in this region is L. clavatum L. var.robustius (Hook. et Grev.) Nakai, and the name of L. clavatnm L. var.asiaticum Ching is a superfluruous name. 2) The name of Diaphasiasitrum com-planatum(L.)Holub has been adopted in this paper instead of D. complanatrum(L.) Holub var. anceps (Wallr.) Ching. Selaginellaceae: Selaginella tamariscina (Beauv.) Spr. var. ulanchotensisChing et Wang-Wei is a unequivocal variety which differs from S. toms-riscina (Beauv.) Spr. var. pulvinata (Hook. et Grev.) Alst. and both ofthem are distributed in N. E. China. Equisetaceae: The previous report of Equisetum variegatum Schleich. byLiou (1958) from N. E. China is partly a mistake for E. variegatum Sch-leich. var. alaskanum A. Eat. and the figure assigned to B. variegatum byhim was drawn based on the specimen of var. alaskanum. Botrychiaceae: The fern generally identified as Botrychium ramosum Asc-hers. and B. manshuricum Ching by authors from China is a mistake forB. boreale (Fries) Milde, a fern that distributed extensively in N. E.Asia. Hemionitidaceae: The present study has shown that the plants of Coni-ogramme in N. E. China are represented by two taxa namely C. intermediaHieron var. glabra Ching and C. affinis (Wall.) Hieron. Aspleniaceae: Asplenium subvarians Ching ex C. Chr. is a fern differsfrom A. varians by obtuser denticles and chromosome number 2n=72 insteadof 144. Dryopteridaceae: 1) Both of Dryopteris fragrans (L.) Schott. var. fragransand var. remotiuscula can been found in N. E. China. 2) The classicalname of D. austriaca (Jacq.) Woynar is a later synonym of D. dilatata(Hoffm.) A. Gray, and there is no D. dilatata in this region. The previ-ous report of D. austriaca (Jacq.) Woynar and D. manshurica Ching fromN. E. China are mistakes for D. expansa (Presl.) Fr.-Jenkins et Jermy.3) There is no D. panda (Clarke) C. Chr. in N. E. China. 4) The reportof D. bissetiana (Bak.)C. Chr. by authors from Dalian is a mistake forD. saxifraga H. Ito. 5) The report of D. uniformis (Makino) Makino byauthors from Dalian is a mistake for D. monticola (Makino) C. Chr. 6) D.coreano-montana Nakai and D. sichotensis Kom. are two. different species, sofar, only the former detected in N. E. China. 7) D. woodsiisora Hayatavar. tenuissima (Tagawa) Li et J. Z. Wang proposed as a name of newcombination. Polypodiaceae: Phymatopsis shandongensis J. X. Li et C. Y. Wang is asynonym for P. hastata (Thunb.) Kitag. var. pygmaea (Maxim.) Li et J. Z.Wang.
