Plagiochila is the largest genus of bryophytes of Colombia. A total of 175 species have been recorded from the country but the majority of these are synonyms. In this paper 57 species are accepted for Colombia. A key to the Colombian species of Plagiochila is provided and each species is briefly described, with data on types, synonyms, published illustrations, morphology, geographical distribution and habitat, as well as a brief discussion of differentiating characters and taxonomic affinity. Among the countries of tropical America, Colombia has the highest diversity of Plagiochila followed by Ecuador (53 species) and Costa Rica (50 species). More than half of the Colombian species are widely distributed throughout tropical America and seven of them occur also in Africa and/or Western Europe. About one fourth of the species are restricted to the northern Andes, which is the centre of diversity of Plagiochila in the New World. The majority of the species grow as epiphytes in humid Andean forests. Diversity peaks in the upper montane forest belt between 2000-3000 m. Sixteen species occur in the páramo belt and five are exclusive to páramo. Eighteen species occur in lowland rainforest. Plagiochila eggersii, recorded from lowland rainforest of the Chocó, is new to Colombia.Key words: Andean forest, bryophytes, Colombia, elevational distribution, liverworts, páramo, Plagiochila, taxonomy. El género Plagiochila (Marchantiophyta) en Colombia ResumenPlagiochila es el mayor género de briófitos de Colombia. Un total de 175 especies han sido registradas para el país, pero la mayoría de estos nombres son sinónimos. En este trabajo se aceptan 57 especies para Colombia. Se proporciona una clave para las especies colombianas de Plagiochila y cada especie se describe brevemente con datos sobre los tipos, sinónimos, ilustraciones publicadas, morfología, distribución y hábitat, así como un breve análisis de sus caracteres principales y afinidad taxonómica. Entre los países de la América tropical, Colombia tiene la mayor diversidad de Plagiochila seguido de Ecuador (53 especies) y Costa Rica (50 especies). Más de la mitad de las especies colombianas están ampliamente distribuidas en América tropical y siete de ellas se presentan también en África y / o Europa occidental. Alrededor de una cuarta parte de las especies están restringidas para los Andes del norte, que es el centro de diversidad de Plagiochila en el Nuevo Mundo. La mayoría de las especies crecen como epífitas en bosques húmedos andinos. La mayor diversidad se encuentra entre 2000-3000 m. Dieciséis especies se encuentran en los páramos y cinco son exclusivas de páramo. Dieciocho especies se encuentran en la selva tropical. Plagiochila eggersii, encontrada en la selva del Chocó, es nueva para Colombia.

Based on morphology and phylogenetical analyses of nrITS sequences, the Andean endemic Plagiochila (Jamesoniella) dependula is placed in Plagiochila sect. Fuscoluteae. Perianths, oil bodies and sporophytes are described for the first time. Morphologically, P. dependula is characterized by entire, dorsally mostly shortly decurrent, laterally appressed, reniform leaves which are covered by irregular papillae and membranous wax platelets, papillose oil bodies, intercalary androecia with opposite bracts that overlap dorsally, a plagiochilid perianth with an entire mouth, a 250 mm thick capsule wall with thickenings in all layers, large 1-4 celled spores, and bispiral elaters. Morphotypes of Plagiochila fuscolutea with laterally appressed leaves differ from P. dependula by an at least moderately decurrent, broad dorsal leaf base, a ¡smooth upper leaf surface, and by its often toothed leaf apices. Plagiochila wolframii is placed in the synonymy of P. fuscolutea. Maximum likelihood and parsimony analyses of 29 Plagiochila ITS sequences resolve P. dependula in a well-supported clade with several other representatives of P. sect. Fuscoluteae. Branch lengths within sect. Fuscoluteae point to a sudden diversification. Accessions of P. heterophylla s.str. from Great Britain (formerly known as P. atlantica) and Costa Rica form an unsupported monophyletic lineage.

Aim This paper presents a synthesis of our recent results regarding the biogeography of Plagiochila using a molecular approach, and documents intercontinental ranges within this largest genus of the hepatics. Methods A maximum likelihood analysis of sixty‐one nrITS sequences of Plagiochila was performed and the molecular topology obtained was compared with morphological, phytochemical and geographical data. Results Our molecular data set allowed the identification of eleven Plagiochila sections, the majority of which cover at least two floristic kingdoms. Seven sections have species in Europe (sect. Arrectae, Carringtoniae, Fuscoluteae, Glaucescentes, Plagiochila, Rutilantes, Vagae). Plagiochila species from Atlantic Europe are usually close to or conspecific with neotropical taxa, whereas species widespread in Europe are closely related to Asian ones and not to those in the Neotropics. Plagiochila sect. Arrectae represents a neotropical – Atlantic European clade. The section is not closely related – as has often been suggested – to the morphologically similar sect. Zonatae from Asia and western North America. Sequence data show that the African P. integerrima and the neotropical P. subplana are members of the Asian sect. Cucullatae (sect. Ciliatae, syn. nov.), which becomes pantropical in distribution. An ITS sequence of P. boryana from Uganda confirms the Afro‐American range of the primarily neotropical sect. Hylacoetes. Similarities in sporophyte morphology between the sect. Cucullatae and sect. Hylacoetes are the result of parallel evolution. Main conclusions Our results indicate that intercontinental ranges at section and species level are common in Plagiochila. Carl's (1931) subdivision of Plagiochila into sections restricted to one floristic kingdom is outdated. Biogeographical patterns in Plagiochila are not dissimilar to those of other groups of bryophytes but elucidation of the geographical ranges of the taxa requires a molecular approach. Contrary to earlier belief, most Plagiochila species from Atlantic Europe do not have close relatives in Asia but are conspecific with or closely related to species from tropical America.
