Olsynium douglasii (A. Dietr.) E.P. Bicknell var. inflatum (Suksd.) Cholewa & Douglass M. Hend.
Annotated Aug 2011. Sources: USDA-NRCS Plants Database. Remarks: Ray J. Davis Herbarium (IDS); taxonomic update

Idaho: Washington County: Midvale.
Common name: Blue-eyed Grass. St. John's original separation of S. douglasii & S. inflatum states that there is a short filament tube in both species but that in S. Douglasii (syn for grandiflorum) there is a slight swelling at base, while in S. inflatum there is a sharp basal inflation (SR). This may be Sisyrinchium inflatum (Suksd.) St. John. and the white-flowers one var. album St. John. I can see no difference but S. grandiflorum is supposed to have the stamens separate from the base and S. inflatum to have them forming a short ??? at base. The original description of S. grandiflorum Dougl. does not describe the base of the stamens. Miss Eastwood. Phenology: Flowers.
