An odd-looking plant, for the foliage looks like pieces of a whisk-broom stuck in the ground. It is six to fourteen inches tall, with a thickish root and minute, sulphur-yellow flowers, forming a flat-topped cluster, about two inches across, without bracts, and composed of three to fifteen smaller clusters, with small bracts; usually only the outermost flowers of both the large and small clusters are fertile. The stem and leaves are stiff and sage-green, the root-leaves with broad leaf-stems, reddish and papery at base, sheathing the stem, and all the leaves cut into narrow divisions, not much thicker than pine needles, folded together so that they appear to be cylindrical. This grows on dry gravelly hills, at an altitude of from six to eight thousand feet.
