Introduction
This is a web version of the paper published in 2008 entitled 'Early Land Plants Today: Liverwort Checklist of Checklists' by Lars Söderström, Anders Hagborg, Matt von Konrat and Matt Renner (see below for full details and to download PDF). Please contact us for errors or updates. Updates indicated by an * in the left margin.
This represents a novel representation of the literature because each article has been assessed if the checklist is specimen based or literature based or a combination thereof. Checklists remain an indispensable tool for setting priorities for conservation action, ecological research, and taxonomic and systematic studies. Broader participation by taxonomic specialists and regional experts will lead to checklists containing high quality data. Key elements that should be included in a checklist include: author citation, original citations, type data, synonymy (including differentiation between homonyms and heterotypic synonyms), distribution, and if not the direct citation of exemplar voucher specimens, then minimally a citation of the source for the record.
The list includes all checklists published since 1900, known to the authors, that fulfill our criteria as covering a botanical country or larger area, and including all liverwort species. In some cases where there is no good recent checklist, we have loosened our requirements. When there is a more recent checklist for a smaller part of the botanical country, we have included it. Also, when there is no good checklist covering all species, we have included lists that cover a larger part of the flora, e.g., all leafy liverworts of Mexico. In addition, we have included lists that comprise full updates of earlier lists without repeating the whole list. We separate different kinds of checklists according to the following categories, although it sometimes is difficult to understand the background of the list.
The categories derived include:
- Specimen based
- Specimens cited
- Literature based
- Original literature cited.
Additional subcategories derived include those checklists that represent a) additional reports (only additions fully updating an earlier checklist); b) only covering part of the territory (see literature list for explanation), and c) only covering part of the species (see literature list for an explanation).

Web navigation: Simply click on the links to obtain the different types of checklists for a region. We generally follow Brummitt (2001) and the limit has been set to level 3 areas (here named botanical countries). These boundaries mostly follow geopolitical boundaries. However, very large coutries such as Russia, U.S.A., China, Brazil etc. are subdivided into administrative units or groups of administrative units.
