Abstract

Abstract:

In the present paper, the circum cription of the genus Dryopteris subgenus Ery-

throvariae (H. Ito) Fraser-Jenkins is revised, and a taxonomic study on the subgenus from

Yunnan Province is carried out .The subgenus contains 2 sections, 12 species in Yunnan, of

which D. yongdeensis W. M. Chu is a new species, D. championii, D. erythrosora, D. gymno-

sora, D. indusiata and D. integriloba are first recorded from Yunnan. The confusion between

Dryopteris labordei and D. gymnosora is clarified, the former being treated as an independent

species.

Key words: Dryopteris Adans., subgenus Erythrovariae, revision, new species, new distribution, classification, Yunnan.
