Plagiochila (Dumort.) Dumort. is one of the largest liverwort genera of Madagascar. A study of the rich Plagiochila holdings from Madagascar kept in the herbaria of Brussels, Eger and Paris leads to the recognition of 22 species, in six sections. One species, P. vandenberghenii Gradst., sp. nov., is new to science and P. bifaria (Sw.) Lindenb., P....

Investigations into the bryophyte flora of Madagascar as part of the MadBryo project, show that five moss genera (Actinodontium Schwägr., Aulacopilum Wilson, Forsstroemia Lindb., Haplohymenium Dozy & Molk., and Herzogiella Broth.) are new for the island. For three additional taxa we clarify the correct name to use for Malagasy specimens. Ectropothe...

Based on collaborative work of a French-Ethiopian team, we investigated the diversity and distribution of Ethiopian trechine beetles (Carabidae, Trechini), in the sub-alpine and afro-alpine ecosystems. Four new genera, three new subgenera and eighteen new species are described from Ethiopian Highland environments

Introduction. Although Madagascar is known for its unique fauna and vascular flora, the country’s bryophyte flora in contrast is understudied and under collected. Arising from a bryophyte collecting expedition undertaken in May–June 2016, this paper describes a new species of simple thalloid liverwort, Fossombronia isaloensis, from Madagascar. Meth...

The conservation status of 770 New Zealand hornwort and liverwort taxa was assessed using the New Zealand Threat Classification System (NZTCS). A full list is presented, along with a statistical summary and brief notes on the most important changes. This list replaces all previous NZTCS lists for hornworts and liverworts.

A taxonomic revision of the liverwort family Aneuraceae in eastern Africa is presented based on the results of an integrative approach. Molecular and morphological data lead to the recognition of fourteen species in eastern Africa, in three genera: eleven species in Riccardia Gray, two in Aneura Dumort. and one in Afroriccardia Reeb & Gradst. One f...

The Cordillera del Cóndor on the border between Ecuador and Peru stands out because of its rich biodiversity and high endemism. Here we describe a new dendroid species of the thalloid liverwort genus Riccardia, R. verticillata Gradst. & Reeb, from El Quimi Biological Reserve in the Cóndor region of Ecuador. The plants consist of a stout, erect axis...

This updated checklist of Marchantiophyta (liverworts) and Anthocerotophyta (hornworts) of Togo was compiled from the literature, from herbarium and recent collections. A total of 56 species including three infraspecific taxa of liverworts and hornworts are recorded for Togo comprising 55 liverworts and one hornwort in 15 families and 29 genera. 14...

We present a contribution to the knowledge of the Malagasy bryoflora that results from a BRYOTAN workshop organized in September 2018 at the Antananarivo Herbarium (TAN) housed at the Parc Botanique et Zoologique de Tsimbazaza, Antananarivo, Madagascar, within the framework of the BRYOTAN project (Bryophytes of TAN). Seven taxa reported here as new...
Poster
Development and digitization of Bryophytes collections at the TAN Herbarium, PBZT Tsimbazaza, Madagascar. To answer to the lack of biodiversity data for bryophytes with focus on mosses, liverworts and hornworts in Madagascar, these tiny plants, mostly unknown by the public have crucial ecological functions in humid forest (water storage with slow r...

We here explore the diversity and ecology, and update the taxonomy of the fern family hymenophyllaceae, which forms one of the most diverse and emblematic fern assemblages in rainforests of the Mascarene archipelago in western Indian Ocean. Since 1999, we extracted data from floras, literature, and field investigations conducted, and from an exhaus...

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...
Article
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. The current classification of this genus is based on morphological and limited-sampling molecular studies. Very few molecular data are available and a comprehensive view of evolutionary relationships within the genu...

Morphometric analysis of organisms has undergone a dramatic renaissance in recent years, embracing a range of novel computational and imaging techniques to provide new approaches to phenotypic characterization. These innovations have often developed piece-meal, and may reflect the taxonomic specializations and biases of their creators. In this revi...

Title : How to make a decision for species hypothesis in an integrative taxonomy approach : the example of African Riccardia. The genus Riccardia, (Aneuraceae) is represented by simple thalloïd pinnate to pluripinnate liverworts. Their highly plastic and irregular morphology involves great difficulties for their description and leads to numerous mi...

Article
The genus Riccardia, Aneuraceae is often considered as puzzling by bryologists, because of its great polymorphism, and African species have not been studied as a whole for several years. A type revision of the African species assigned to Riccardia is presented in order to get a clear view of the historical background before examination of recent ma...
