General Description: Hiker's Gentian has erect, usually simple stems that are 10-20 cm tall. The 2-5 pairs of opposite leaves are broadly lance-shaped to ovate and are 1-6 cm long; the upper are longer and narrower. Herbage is glabrous. The flowers are solitary at the ends of the stems. The calyx is 15-20 mm long and has four deep lobes at its top. The deep blue, funnel-shaped corolla is 20-40 mm long, four-parted, and lobed over nearly half its length. The lobes have small teeth along the sides but are rounded and entire-margined at the tips. The notches between the lobes are not plaited or fringed.
Diagnostic Characteristics: This species can be distinguished from the more common G. DETONSA by the unbranched stems and entire-margined tips of the corolla lobes.
Habitat Comments: Mountain bogs and meadows, at mid-elevations.
