Habitat: Cool ravines, wet moss and alpine rocks. [Alpine or subalpine (non-forested, upland)]
Range: Alaska to Greenland, south to the mountains of Maine and New Hampshire.
Aids to Identification: Speedwells are small herbs whose flowers have 4 petals, typically the lowermost is smaller than the other 3, and they have only 2 stamens.

Leaves are opposite, elliptic in shape, sometimes slightly toothed, and 1-4 cm long. The similar and common V. serpyllifolia is found at lower elevations and has stems that are prostrate at the base rather than erect from the base.
