[Type: Utah, Emery Co., Lower Crossing, of the Price River, near Woodside, not "[of the Colorado River]" as with the protolog, M. E. Jones 6412, 2 Jul 1898, holotype US!, isotypes BRY!, POM!] Yellow-flower

Perennial herbs from a subrhizomatous woody caudex; stems 20–50 cm tall, foliose to the middle or above; leaves 2–7.5 (10) cm long, 4–25 mm wide, pinnately incised, minutely puberulent and glandular-punctate; heads solitary, on peduncles to 25 cm long; disk 17–32 mm wide, yellow; involucral bracts sparingly to moderately villous, green, caudate-attenuate; rays 8–12, yellow, 12–17 mm long, the lobes 3–5 mm long; setae of receptacle well developed, coarse and spinescent; disk corollas sparingly villous, the hairs with colorless cross-walls, the lobes acute; pappus scales oblong to oblanceolate, abruptly contracted to a barbellate appendage; achenes ca 1–1.5 mm long, yellowish pilose.

Stream terraces and valley bottoms, commonly in cottonwood, willow, and tamarix communities in Desolation and lower Price river canyons and near vicinity at 1280 to 1650 m in Emery and Grand cos.; a Navajo Basin endemic; 23 (vi).

Plants of this remarkably distinctive species are extremely resinous glandular, with a very bitter-flavored exudate – this discovered after constructing a sandwich following pressing of yellow-flower plants. Despite the assumption by Rydberg (see above) that the original material was taken at the Lower Crossing [of the Colorado River], the plants are known from only along the lower Price River (where Lower Crossing was adjacent to the coal cliffs east of Woodside where the Price River penetrates to the Green), and along the Canyon of the Green River north of Gunnison Butte, where it grows on rubble from the coal-bearing Cretaceous Mesa Verde Group of formations. Despite the distinctive nature of G. flava it is synonymized insensibly within G. pinnatifida in FNA 21: 423. 2006.
