Gentiana platypetala
Gentiana linearis
Gentiana platypetala is restricted to sites near the Pacific largely confined to the insular ranges of British Columbia and southern Alaska from northern Vancouver Island, Queen Charlotte Islands, and Alice Arm, British Columbia, northwest to Kodiak Island, Alaska, but occasionally on mainland coastal ranges.
The distinctive spathaceous calyces of this species are strongly suffused with reddish purple.

Gentiana linearis is extirpated from New Jersey. Reports from Manitoba and Minnesota have been based on circumscriptions of G. linearis that included G. rubricaulis, mostly prior to the recognition of G. rubricaulis as a distinct species in standard floras. A report from North Carolina is incorrect, having been based on a misunderstanding as to where a photograph was taken (W. F. Hutson, pers. comm.). Narrow-leaved specimens of G. saponaria are occasionally misidentified as G. linearis but can be distinguished by their ciliate calyx lobes and by the shape of the calyx lobes and the free portions of the corolla plicae.
