Nomenclatural note. Veronica anagallis-aquatica var. pubescens is described as being short pubescent from all sides. As type, Bentham stated the Iranian collection Aucher-Éloy no. 5100. The type material has the pyramidal capsule and long style characteristic of V. michauxii . So, it is best considered to be a synonym of that taxon rather than V. anagallis-aquatica s.str. Since Bentham again seems to have seen only the material of Boissier in Geneva (“v.s.”) and no specimen is available in Kew, that material is chosen as lectotype, although it is not labelled with the name. Morphological and molecular analyses did not suggest a deeper significance for pubescence in the taxonomy of the species (Hosseinnejad Azad et al. 2020, 2021).
