Description
Nothocalais troximoides is a perennial herb growing from a stout root and a thick caudex and producing a woolly flower stem up to about 25 cm (10 inches) 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 and a thicker fringe of hairs on the leaf edge. Each linear leaf has a prominent mid-rib that is usually paler in color and they are up to 30 cm (12 inches) long. Each flower stem bears a single flower and the flower head is 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 cm (1⁄2 inch) long not including the large pappus of up to 30 silvery white bristles which may be an additional 2 cm (3⁄4 inch) in length.[1]
