The Global Flora is a new international serial for botanical taxonomy, to provide accepted species-level classifications for all vascular plant families. The serial has three series: (A) Angiosperms (following APG IV, 2016); (B) Lycopods, Ferns and Gymnosperms (classification following Christenhusz et al., 2017); and (C) special editions. The first two series will only treat monophyletic taxa on a global scale (e.g. family, subfamily, tribe, genus or section). The special editions series aims to make significant contributions to the body of plant systematic knowledge and typically will be of a global botanical scope.
