Abstract
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.) Gradst. & C.J.Bastos comb. nov., C. rigidula var. autoica C.J.Bastos & Gradst. var. nov., C. timboensis C.J.Bastos & Gradst. sp. nov., C. trifaria var. clausa (Nees & Mont.) C.J.Bastos & Gradst. comb. nov.
