稀省知道的不丹疣鏻苔（新擬）Cololejeunea bhutanica Grolle & Mizut。和锡蘭疣鏻苔（新擬）Cololejeunea ceylanica Onr。原分别分布於不丹和斯蘭卡，最近我们发现它们各自分在广西和西藏。以前僅日本有报道的堀川疣鏻苔（新擬）Cololejeunea horikawana (S. Hatt). Mizut。亦分布於云南。堀川疣鏻苔兴单體疣鏻苔Cololejeunea goebelii (Gottsche ex Schiffn). Schiffn。相似，但副體的大和透明疣的平置不同。泛热带分布的魏氏疣鏻苔（新擬）Cololejeunea wightii Steph. 亦发现分布在广西和海南。南亚疣鏻苔Cololejeunea temella Benedix为台湾新记录重。依據镰刀关的葉子，或多或少2a关的中齿以及油胞状葉基部细胞的存在，南亚疣鏻苔易兴其它台湾产的疣鏻苔属植物区分。原分布於印度，中国西藏及海南的擬斜葉疣鏻苔Cololejeunea pseudoplagiphylla P.C.Wu & J.S.Lou 为赵南新记錄植物。本广也提供不丹疣鏻苔，南亚疣鏻苔和魏氏疣鏻苔的详盡图解。

Metalejeunea winkleri R.L.Zhu & Grolle is described and illustrated as a species new to science from Borneo. The new species is immediately separated from the pantropical Metalejeunea cucullata (Reinw. et al.) Grolle by the obcordate and strongly dorsiventrally compressed perianth with only three keels.

Drepanolejeunea subacuta (Horik.) H.A. Mill. et al. and Lejeunea lancistipula (Steph.) H.A. Mill. et al., previously known only from Taiwan and New Guinea, respectively, are proposed as synonyms of Lejeunea exilis (Reinw. et al.) Grolle. Lejeunea exilis is a highly variable species and its diagnostic characteristics include (1) dimorphic underleaves (bilobed and subulate-ovate), (2) very small size of plants, (3) eplicate perianths always strongly emergent, (4) highly variable shape of leaves, (5) acute to apiculate leaf apex of the leaf in well developed plants, and (6) asexual reproduction usually by means of ribbon-like marginal regenerants. Lejeunea exilis is reported for the fi rst time for China. A detailed description and illustrations of Lejeunea exilis are provided. The occurrence of ribbon-like marginal regenerants in the Lejeuneaceae is discussed.

Strepsilejeunea boliviensis Steph., a rare species endemic to Bolivia, bears eplicate perianths, emarginate to shortly bilobed apices of underleaves, and usual presence of blunt second tooth of the leaf lobule. It is transferred to the genus Lejeunea, primarily based on the large leaf cells and proximal hyaline papilla.

Cololejeunea javanica (Steph.) Mizut. and C. mackeeana Tixier are proposed as synonyms of C. angustiflora (Steph.) Mizut. Cololejeunea flavicans (Steph.) Mizut., previously synonymous with C. javanica, is reinstated. The position of hyaline papilla in Cololejeunea ciliata P
