Discussion | Stem indument of Veronica peregrina has been used to distinguish var. xalapensis with a glandular-hairy stem (F. W. Pennell 1935), a variety that seems to be confined to drier places than the type variety. Variety laurentiana is also differentiated from var. peregrina in having a glandular-hairy stem, fleshier leaves, shorter stamens, smaller corollas, and slightly differently shaped capsules (Frère Marie-Victorin and J. Rousseau 1940). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The description provided here for Veronica chamaedrys is solely for the tetraploid cytotype, most probably the exclusive cytotype in the flora area and in central and western Europe. The diploid cytotype is so far only known from eastern and southeastern Europe (K. E. Bardy et al. 2010). A significant change in morphology can occur in shaded habitats, in which especially the petiole can be elongated beyond the range given. It is unclear whether Veronica chamaedrys is introduced throughout the flora area; it may be native in northeastern areas of North America.
