Phytocannabinoids: a unified critical inventory.

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.

World checklist of hornworts and liverworts.

In Europe and Macaronesia 453 species of Hepaticae (Marchantiopsida, Liverworts) are recognized; 33 of these are confined to Macaronesia. The total species complement is assigned to 105 genera (of which four are confined to Macaronesia: Acanthocoleus R.M.Schust., Cheilolejeunea (Spruce) Schiffn., Mnioloma Herzog and Tylimanthus Mitt.). The genera are subdivided into subgenera and sections where sound natural groupings of species are recognizable. Two new subgenera and a new section for Asterella P.Beauv. are proposed. Correct author citations for a number of sectional names are given following strict interpretation of Art. 22.1, including the new combination Marsupella sect. Homocraspis (Lindb. ex Schiffn.) Grolle. Two species in the genus Lophozia and one in the genus Frullania are newly synonymized. A neotype for Jungermannia ventricosa Dicks. (Lophozia ventricosa (Dicks.) Dumort.) is designated. The five extant genera Metacalypogeia (S.Hatt.) Inoue, Nipponolejeunea S.Hatt., Notoscyphus Mitt., ...

Recognition of two different species in the liverwort genusMonoclea
Hook. (monotypic orderMonocleales), viz.M. forsteri
Hook. in New Zealand andM. gottschei
Lindb. in the New World, is supported by characteristics of the sporophyte, antheridial receptacle and secondary metabolites.M. gottschei produces the greatest variety of flavonoids and the largest amount of bisbibenzyls ever encountered in a liverwort. In contrast,M. forsteri is poor in secondary metabolites. Two allopatric subspecies are recognized inM. gottschei, based on characteristics of the antheridial receptacle: subsp.gottschei in Chile (Valdivian region, Juan Fernandez Is.) and subsp.elongata
Gradst. & Mues, subsp. nova, in tropical America. The exclusive occurrence inMonoclea of glucuronide and galacturonide flavone glycosides and the fact that capsule dehiscence may take place before full elongation of the seta are new arguments in support of the placement ofMonocleales in theMarchantiidae.
