A preliminary analysis of geographical elements of the lichen genus pertusaria from china is given in the text . of the forty - five species , seven ( 15 % ) are endemic to china , two ( 4 % ) are cosmopolitan , nine ( 20 % ) are circumpolar , eight ( 17 % ) are pantropical , seven ( 15 % ) are eurasian , five ( 9 % ) are east asian - north american , seven ( 15 % ) are east - asian and two ( 4 % ) are sino - himalayan . all the specimens examined by the writer are deposited in the following herbaria : hmas - l , hkas , nnu , abl , canl , w and sdnu 本研究所检查的标本保存于以下标本馆：中国科学院微生物研究所菌物标本馆( hmas - l ) 、中国科学院昆明植物研究所隐花植物标本馆( hkas ) 、南京师范大学植物标本室( nnu ) 、加拿大自然历史博物馆( canl ) 、奥地利维也纳自然历史博物馆( w ) 、荷兰cbs的标本室( abl )以及山东师范大学植物标本室( sdnu ) 。

Following the east element , the north temperate elements consist of 53 species corresponding to 29 . 94 % of the total . the tropical elements ( including pantropical element , paleotropical element and india - malaysia element ) consist of 38 species sharing 21 . 47 % of the total . the results show that the houhe national nature reserve is transitional climatic belt where the tropical and subtropical elements extend northwards and the north temperate elements infiltrate southwards , which accords with its geographical location 本文按现有资料，并参照吴征镒先生对中国种子植物属的分布区类型的划分，将后河自然保护区藓类植物划分为9种成分，其中东亚成分是最丰富的成分，有65种，占总数(扣除世界广布种，下同)的36 . 72 ，北温带成分有53种，占29 . 94 ，仅次于东亚成分，热带成分(包括泛热带成分、古热带成分和热带亚洲)有38种，占总种数的21 . 47 。
