Biogeographical notes on the moss floras of Bicol Peninsula in Luzon and the Catanduanes Islands, the Philippines

Substantial moss collections have been made in Bicol peninsula and neighbouring Catanduanes Island, which form a special focus in the southeastern part of Luzon, the Philippines\u27 largest island. Moss diversity in the study area has now increased to 124 genera and 292 species. As expected, the moss flora has a predominant Luzon character, wherein about 34 species (11.64%) are restricted to Luzon, while about 18 species (6.16%) are new to the study area. Three species: Phyllodon lingulatus (Cardot) W. R. Buck, Aerobryopsis leptosigmata (Mull. Hal. ex Broth. & Geh.) M. Fleisch., and Calyptothecium squarrosulum Nog. & B. C. Tan are restricted to the study area, while one species, Acroporium convolutum (Bosch & Sande Lac.) M. Fleisch., previously reported for the Philippines but without a documented locality, is reported here with a locality information. Calymperes couguiense Besch., Leptotrichella sumatrana (Dixon) Ochyra, Papillidiopsis macrosticta (Broth. & Paris) W. R. Buck & B. C. Tan, Physcomitrium sphaericum (C. F. Ludw.) Furnr., and Sematophyllum phoeniceum (Mull. Hal.) M. Fleisch. are new Philippine records
