Setyawan AD. 2015. Diversity and distribution of Selaginella in the southern West Java based on altitudinal gradient. Pros Sem Nas Masy Biodiv Indon 1: 490-496. Western Java has a wet climate and hilly terrain, which are very suitable for the growth of Selaginella. This study was conducted to determine the diversity and distribution of Selaginella from the highlands of Cibodas Biosphere Reserve (Mount Gede-Pangrango National Park) to the south coast lowlands of Cianjur, West Java. Field studies were conducted between 2012 and 2013, accompanied by observations of the Herbarium Bogoriense collection, Biological Research Center, Indonesian Institute of Sciences (LIPI), Cibinong, Bogor. In this study, it was found 13 species of Selaginella that were distributed from the coastal areas to montane forest regions as well as three unidentified taxa. S. ciliaris and S. plana were commonly found at lower altitudes, whereas other species such as S. opaca and S. remotifolia, and S. subalpina, occurred predominantly at higher elevations. Some species were found between the two areas, namely S. aristata, S. ornata, S. willdenowii, S. intermedia, S. involvens, and S. uncinata. The latter species is an alien species that has naturalized in the nature. In addition, in the southern coastal region of Sukabumi and Cianjur were found several variants of S. ciliaris that require further study to ascertain their identity.
