State Rank Reason (see State Rank above)
Rare in Montana, where it is known from several widely scattered locations. Current population levels and trends are unknown, though potential threats to known populations appear to be minimal or non-existent at this time. Additional sites are likely to be documented if surveys were to be conducted.
 
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.

Phenology
Flowering in July-August.

Diagnostic Characteristics
This species can be distinguished from the more common Gentianopsis detonsa by the unbranched stems and entire-margined tips of the corolla lobes, and from G. aquatica by the blue corolla.
