Erigeron geiseri is characterized by its annual duration and slender taproots, relatively small size, lobed basal leaves, peduncles often dilated near the heads, obovate phyllaries with broad, scarious margins, and relatively small disc florets and cypselae, the latter with pappi of conspicuous scales and relatively few bristles.
