Collomia linearis grows to about 15 inches tall, and is usually unbranched except perhaps near the top of the plant. The cauline (stem) leaves are narrow and lance-shaped, and are pretty much the same size all the way up to the bracts which subtend the terminal inflorescence. The stem and underside of the leaves are normally hairy, and the upper surface of the leaves are normally smooth. There are also basal leaves.
