ADDITIONS TO THE MOSS FLORAS OF MT. WILHELM NATURE RESERVE AND MT. GAHAVISUKA PROVINCIAL PARK, PAPUA NEW GUINEA

抄録

  A total of 101 genera and 174 species of mosses are accounted for Mt. Wilhelm in Papua New Guinea based on past and present collections made from 2000-4300 m elevations. Twenty-two species are new records for the mountain and Brotherella longipes is reported as new to New Guinea as well as East Malesia. Leptotypication of B. longipes is also proposed. Meteorium buchananii is excluded from Australasia including New Guinea. Aptychella clemensiae Bartr., Camptochaete papuana Tangney, Chaetomitrium parcesetulosum Bartr., C. subplicatum Bartr., C. plicatum Bartr., Eurhynchium bergmaniae Bartr. and Meteorium longipilum Nog. are suggested to be new synonyms. One new combination, Warburgiella celebensis (Dix.) B. C. Tan, is proposed.
