Cryptantha angustifolia is an annual herb usually under half a meter in height and covered in long hairs and bristles. It has a number of small linear leaves mostly toward the base of the plant. The erect stems are covered by inflorescences in a cane-shaped curl similar to the flowers of fiddlenecks. Each flower is white with yellow throat parts and a few millimeters wide.
