Gentiana platypetala
Gentiana setigera
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 setigera is endemic to Gasquet Mountain, Del Norte County, and Red Mountain, Mendocino County, California, and a small area in Josephine County, Oregon. At the Oregon site, it has been called G. bisetaea or Waldo gentian. Reports from other sites have been based on G. plurisetosa, with which G. setigera has often been confused.
K. L. Chambers and J. Greenleaf (1989) and C. T. Mason (1991) distinguished Gentiana plurisetosa from G. setigera, clarified the nomenclature of G. setigera, and included G. bisetaea in G. setigera. Prior to those studies, all components of this complex had been of conservation concern. With G. plurisetosa comprising only a part of this complex, and with G. setigera now being more narrowly circumscribed, conservation concern remains appropriate for both of these species.
