Number of Occurrences81 to >300

Rank Reasons

Perhaps 40-50 or more locations, but species is widespread in the western U.S., and many sites have probably not been collected. Idaho HP ranks 'S4' in state (2Feb94).

Range Extent Comments

Cascades of Oregon south to the Sierra Nevadas of central California, and east through Oregon to south-central and western Montana, Idaho, and Nevada. Peripheral.

Occurrences Comments

Gillett (1957) gives 29 locations; perhaps 40-50 sites?? Idaho HP (2Feb94) ranks 'S4' in state.

Threat Impact Comments

Species occurs in timbered areas of the northwest which are subject to logging activity.

Ecology & Habitat

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

Mountain bogs and meadows, at mid-elevations.
