Studies on Taxonomy and Geographical Distribution of Meteoriaceae in Jiangxi

Meteoriaceae is one of the largest families of bryophytes in tropical and subtropical regions. It consists of two subfamilies: Pilotrichelloideae distributed mainly in South America and Meteorioideae in Southeast Asia. So far, there are 10 genera and 28 species of Meteoriaceae known from Jiangxi. This figure represents about 83.3% of the total genera and 39.4% species of Meteoriaceae in China, about 83.3% and 31.5% in Asia. The family Meteoriaceae in Jiangxi is mainly distributed in northeastern, northwestern and southern parts of the province. According to statistical analysis, the distribution of Meteoriaceae in Jiangxi can be divided into three groups. The discussion on the distribution pattern for each genus and the relationship between the horizontal and vertical distribution of Meteoriaceae in Jiangxi are dealf with in this paper.
