Discussion

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.
