A REVISION OF THE EAST-ASIAN SPECIES OF CAMPYLOPUS

Abstract

  A revision of all taxa of Campylopus reported for E Asia (China, Korea, Japan and Taiwan) revealed thirteen species and two subspecies. Campylopus gracilis (Mitt.) Jaeg. has proven to be synonymous with C. subulatus Schimp. in Rabenh. and is reported here as new to Japan. Campylopus gracilentus Card. described from Taiwan is synonymous with the SE-Asian C. laxitextus Lac. Campylopus fragilis ssp. goughii (Mitt.) Frahm (C. goughii (Mitt.) Jaeg.) and C. fragilis ssp. zollingerianus (C. zollingerianus (C. Müll.) Bosch & Lac.), C. crispifolius Bartr., C. boswellii (C. Müll.) Par. are reported as new to China. Campylopus involutus (C. Müll.) Jaeg. is synonymous with C. ericoides (Griff.) Jaeg. Campylopus yakushimensis Sak. and C. japonicus Broth. var. fuscoviridis Card. have proved to be inseparable from C. atrovirens De Not. and are regarded as synonyms of the latter. Campylopus atrovirens is reported for the first time with sporophytes. Lectotypes have been chosen for Campylopus ericoides, C. involutus and C. gracilentus.
