What may be a small-flowered trillium observed atop Grizzly Peak, Jackson County, OR.......May 27, 2021. This specimen keys out to this taxon based upon flower size, but it would be more than one hundred miles out of range to the south of its normal Willamette Valley and southwestern Washington range. Otherwise, it would be ssp. albidum which is abundant in this general area.
