Siskiyou buckwheat is a California native perennial found in the eastern Klamath Ranges, specifically in the Mount Eddy and Scott Mountains, growing on serpentine terrain at elevations of 1,600 to 2,800 meters. Flowering from July to September, this plant produces yellow flowers in compact heads about 1 centimeter wide with distinctive reflexed involucre teeth. Growing as a matted perennial with stems 5 to 15 centimeters tall, it forms dense ground-covering clusters up to 5 decimeters in diameter. Its basal leaves are small, about 5 to 8 millimeters long, with a dense whitish tomentose undersurface that contrasts with the sparsely hairy upper surface. The involucres are woolly and tomentose, with 6 to 10 lobe-like teeth that give the flowering heads a distinctive textured appearance.
