Abstract
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.
