Preliminary study on the Bryoflora in Napo County of Guangxi
摘要
Abstract
475 bryophyte specimens from Napo County of Guangxi were collected through filed and carefully identified. It was found that there were 163 species( including subspecies and variation) which belonged to 81 genera in 40 families. And 34 of them were newly recorded in Guangxi. According to the checklist, the main families were Hyp-naceae,Pottiaceae,Meteoriaceae etc. ;and the main genera were Bryum, Hypnum,Rhynchostegium etc. In floristic compositions, the East Asia took up a predominant position(30. 06%),the temperate elements and the tropic elements had a high inverse proportion,showing the transition characteristics from north to south;compositions endemic to China occupied 14. 11% oi the total, and they were located in the transition zone of distribution center of Chinese endemic species. Comparing the moss flora between Red River region and Daweishan Nature Reserve,it was showed that Kroeber index on similarity between Napo County and Daweishan Nature Reserve are higher than that between Nopo county and Red River region. The floristic spectrum of Napo county showed the highest percentage of elements of East Asia type,and it should be classified into Lingnan zone.关键词
