Nothocalais troximoides is a species of flowering plant in the aster family known by the common name sagebrush false dandelion. It is native to western North America, including British Columbia and the northwestern United States, where it grows in sagebrush and other plateau and mountain habitat types. It is a perennial herb growing from a thick caudex and producing a woolly stem up to about 25 centiemeters tall. The leaves are located around the base of the stem and often have crinkled wavy edges, and sometimes a thin coat of small hairs. They measure up to 30 centimeters long. The flower cluster is a flower head lined with green, sometimes purple-speckled, phyllaries and containing many yellow ray florets and no disc florets. The fruit is a cylindrical achene up to 1.3 centimeters long not including the large pappus of up to 30 silvery white bristles which may be an additional two centimeters in length.
