Discussion | Veronica agrestis is similar to the more frequent V. persica and probably frequently overlooked and to be expected elsewhere. However, it should be noted that it is less common than V. persica or V. polita and always in more humid habitats. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Veronica filiformis is self-incompatible. In the flora area, plants seldom produce capsules; it is dispersed by stem cuttings. The species is native to subalpine meadows in the Caucasus and northern Turkey. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
