唇鳞藓属(Cheilolejeunea)是鳞藓科(Lejeuneaceae)最大的属之一,广泛分布于热带和亚热带地区。我们提出了一个改进和更新的分类综合属在热带美洲。在七个部分中,有54个种和6个变种被确认;被接受的新热带物种的数量减少了约20%。本文提供了一个新热带区唇鳞藓属的分类检索表,并对每个种和变种作了简要描述,提供了鉴别特征、分布和已发表的插图资料。提出了16个新异名和2个新选型,新名称为:C.粗鳞藓组(Trachylejeunea(Spruce)C. J.巴斯托斯& Gradst.)组合11月,C.无雌蕊变种滨水区(Steph.)C. J.巴斯托斯和格拉德斯特。组合11月,C. lobulata(Lindenb.)格拉德& C. J.巴斯托斯comb. nov.,C.刚性湾巴斯托斯和格拉德斯特变种十一月,C.巴斯托斯& Gradst.新种,C.特里法里亚湾clausa(Nees & Mont.)C. J.巴斯托斯和格拉德斯特。梳新
Cheilolejeunea is one of the largest genera of Lejeuneaceae and is widely distributed in tropical and subtropical regions. We present an improved and updated taxonomic synthesis of the genus in Tropical America. Fifty-four species and six varieties are recognized, in seven sections; the number of accepted neotropical species is reduced about 20 percent. A key to neotropical taxa of Cheilolejeunea is provided and each species and variety is briefly described with data on differentiating characters, distribution and published illustrations. Sixteen new synonyms and two new lectotypifications are proposed; new names are: C. sect. Trachylejeunea (Spruce) C.J.Bastos & Gradst. comb. nov., C. aneogyna var. riparia (Steph.) C.J.Bastos & Gradst. comb. nov., C. lobulata (Lindenb.)
