, the only member of this genus, is most widespread in the Rocky Mountains of Colorado and New Mexico; it also occurs along the margins of the Colorado Plateau, and scattered locations to the south. This species is related to plants in the solidago genus, differing in such aspects as the larger flowerheads, the wider and longer leaves, the more prominent ray florets and the leaf-like phyllaries and involucral bracts.
Stems have a fine covering of short, glandular hairs, while leaves are also minutely glandular, but otherwise hairless. Flowerheads are arranged in one or more flat-topped clusters, of up to six; they have between 12 and 20 yellow ray florets, crossed by darker veins, and from 25 to 37 yellow disc florets. Phyllaries are broad and hairless, and often partly obscured by the leaf-like bracts below.
