A checklist of the hepatics and anthocerotes of Panamá

A brief account of the geography and floristic regions of Panamá is complemented with an historical account of the liverwort studies of this country. This is followed by an annotated checklist of 289 taxa, including 93 new for Panamá. Among these are four hornwort taxa that represent the first anthocerotes reported. Each checklist entry comprises proper taxon citation, collection data and/or bibliographic references.Una revisión de la geografía y regiones florísticas de Panamá es complementada con una nota histórica de los estudios sobre hepáticas de este país.

World checklist of hornworts and liverworts

A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here present the first-ever worldwide checklist for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species in 398 genera representing 92 families from the two phyla. The checklist has far reaching implications and applications, including providing a valuable tool for taxonomists and systematists, analyzing phytogeographic and diversity patterns, aiding in the assessment of floristic and taxonomic knowledge, and identifying geographical gaps in our understanding of the global liverwort and hornwort flora. The checklist is derived from a working data set centralizing nomenclature, taxonomy and geography on a global scale. Prior to this effort a lack of centralization has been a major impediment for the study and analysis of species richness, conservation and systematic research at both regional and global scales. The success of this checklist, initiated in 2008, has been underpinned by its community approach involving taxonomic specialists working towards a consensus on taxonomy, nomenclature and distribution
