Riccardia is a large genus of thalloid liverworts and notoriously difficult in terms of species recognition. Thirty six species were recognized in the tropical Andes but many of these are not well-defined. In this paper fourteen species are accepted for Colombia and Ecuador; eighteen species and two varieties are reduced to synonymy. Descriptions a...

Riccardia amazonica is one of the most widespread tropical species in the genus Riccardia, occurring on soil, shaded rock and rotten wood in lowland and montane rainforests throughout tropical South America. A study of type specimens shows that the name R. amazonica should be replaced by R. regnellii. The latter species has been confused with R. sp...

Morphometrics, the assignment of quantities to biological shapes, is a powerful tool to address taxonomic, evolutionary, functional and developmental questions. We propose a novel method for shape quantification of complex modular architecture in thalloid plants, whose extremely reduced morphologies, combined with the lack of a formal framework for...

The bryophyte flora of the Sahelian region of sub-Saharan Africa is characterized by a low species richness, but is also extremely poorly documented. We present here the results of a floristic survey in Kedougou (eastern Senegal), which yielded 22 species. Two liverworts and 15 moss species are new to the country, so that the bryophyte flora of Sen...

Background Many organisms such as plants can be characterized as complex-shaped branching forms. The morphological quantification of the forms is a support for a number of areas such as the effects of environmental factors and species discrimination. To date, there is no software package suitable for our dataset representing the forms. We therefore...

With 280 accepted species, the genus Riccardia S.F.Gray (Aneuraceae) is one of the most speciose genera of simple thalloid liverworts.
