Veronica officinalis A. A. Reznicek

A Eurasian species rather frequently escaped from cultivation and well established, forming large prostrate colonies often in natural-appearing habitats. Forests (deciduous, coniferous, mixed, dry to swampy), especially along trails and in clearings; pine plantations; occasionally in disturbed open ground and on rocky outcrops; less often a weed in yards and disturbed ground. First collected in 1894 in Ingham Co.

The low habit and obcordate fruit are similar to those of V. chamaedrys, but besides the smaller flowers and shorter pedicels, V. officinalis has leaves more shallowly toothed, more broadly obtuse or even rounded at the apex, and with lateral veins obscure instead of strong all the way to the teeth (or sinuses). The inflorescence is usually rather densely glandular-pubescent.
