Summary

Based on the most recent evidence from phylogenetic analyses of Veronica and its related genera we propose a new intratribal and intrageneric rearrangement for Veronica and Veroniceae. These recent analyses have settled the long dispute about the relationship of the Northern Hemisphere Veronica and the Southern Hemisphere Hebe complex and have shown the derivation of the latter from within the former. Other genera such as Synthyris and Pseudolysimachion are also derived from within Veronica. A classification based on monophyletic genera therefore needs to either lump some well recognized genera to a large genus Veronica or split Veronica into several genera that seem impossible to separate using morpholgical or structural characters. We discuss the advantages and disadvantages and conclude that it is best to recognize a large genus Veronica (including Hebe, Parahebe, Chionohebe, Heliohebe, Detzneria, Derwentia, Pseudolysimachion, Synthyris and Besseya) with 13 subgenera along with Scrofella, Veronicastrum (inclusive Calorhabdos and Botryopleuron), Lagotis, Wulfenia, Kashmiria, Picrorhiza, Wulfeniopsis and Paederota in Veroniceae.
