Abstract: This paper deals with floristics and the ecological distribution of bryophytes in the evergreen broadleaved forests of Daweishan Nature Reserve (22°28′~22°45′ N, 103°39′~103°51′ E) by means of the Point Central Quarter Method. A total of 134 species representing 34 families and 66 genera were reported, among them 59 species (44.0% of the total) belonging to East Asian elements, and 53 species (39.6%) to tropical ones. The ecological distribution of bryophytes in the evergreen broadleaved forests of Daweishan Nature Reserve can be divided into four main types: (1) Epixylophytia (2) Geophytia; (3) Petrophytia; (4) Epiphyllitia. By Kroeber′s percentage of similarity, the index of similarity is high among Daweishan Nature Reserve , Baishanzu Nature Reserve and Huaping Nature Reserve at the level of family and genus. It, however, is low at species level. Chinese names of eight species, Brotherella complanata, Brotherella curvirostris, Clastobryopsis robusta, Sinskea flammeum, Sinskea phaea, Toloxis semitorta, Trachycladiella aurea and Trachycladiella sparsa, are newly given.
