TL;DR: The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants.

TL;DR: The first-ever worldwide checklist for liverworts and hornworts is presented that includes 7486 species in 398 genera representing 92 families from the two phyla, 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.

TL;DR: Evaluated the seven main candidate plastid regions in three divergent groups of land plants, no single locus showed high levels of universality and resolvability and when multiple loci were combined, fewer barcodes were shared among species.

TL;DR: In 373 annotations, the taxonomy, nomenclature and synonymy of many of the accepted species are discussed briefly, based primarily on recent literature sources and the authors' observations.

TL;DR: This work states that liverworts are a heteromorphic life cycle in which the sporophyte is comparatively shortlived and nutritionally dependent on the free-living gametophyte, but differ from both in numerous anatomical features as detailed by Crandall-Stotler (1984).
