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.

“…ex Nees) Lindenb., a leafy liverwort, to test for variation in desiccation tolerance among three colonies and between the sexes along stream edges where microhabitats variation might occur. Plagiochila is a genus of worldwide distribution, with ~700 species recognized [28,29]. At least two species of Plagiochila have been reported as desiccation-tolerant; these studies focused on documenting the physiological response to a desiccation event [30][31][32][33][34] and not intraspecific variation in desiccation tolerance.…”

Water scarcity, a common stress factor, negatively impacts plant performance. Strategies to cope with it, such as desiccation tolerance, are becoming increasingly important to investigate. However, phenomena, such as intraspecific variation in stress responses have not received much attention. Knowledge of this variability and the environmental drivers can be leveraged to further investigate the mechanisms of desiccation tolerance. Here we tested for variation in desiccation tolerance in Plagiochila porelloides among colonies and sexes within the same riparian zone. Field-collected dehardened plants were subjected to a desiccation event, under controlled conditions and then rehydrated. Plant water status, photosynthetic rates, net carbon gain, and efficiency of photosystem II (PSII) were assayed to evaluate tissue desiccation, basic metabolic processes and plant recovery. To establish a linkage between plant response and environmental factors, field light conditions were measured. We detected intraspecific variation, where a more exposed colony (high percentage of open sky, large temporal range of light quantity, and high red/far-red ratio) showed sex differences in desiccation tolerance and recovery. Overall, PSII recovery occurred by 72 h after rehydration, with a positive carbon gain occurring by day 30. This within species variation suggests plastic or genetic effects, and likely association with light conditions.

A widely accessible list of known plant species is a fundamental requirement for plant conservation and has vast uses. An index of published names of liverworts and hornworts between 2015 and 2016 is provided as part of a continued effort in working toward maintaining an updated world checklist of these groups. The list herein includes 64 higher taxon names, 225 specific names, 35 infraspecific names, two infrageneric autonyms and 21 infraspecific autonyms for 2015 and 2016, including also names of fossils and invalid and illegitimate names. Thirty-three older names omitted in the earlier indices are included.
