Caudices woody, fibrous-rooted. Stems erect to declined, puberulent. Leaves: petioles 8-30 mm; blades mostly 3-9 × 2-5.5 cm, bases truncate to cordate, margins crenate-serrate to serrate, faces minutely and sparsely puberulent. Corollas 3.5-4.5 mm. 2n = 20.

Leaves: Leaves deltoid or triangular-ovate, thin, with crenate to serrate margins and truncate to cordate bases, the faces minutely to sparsely puberulent.

Flowers: Heads discoid, disks bright white, discoid, 28-35, with small bracts around the base of the involucre, heads born on slender penduncles, often nodding, in few-headed cymose panicles at stem tips.

Fruits: Achenes 5-ribbed.

Ecology: Found among limestone boulders, crevices, sandstone bluffs, ridge tops, in pine forests to mixed conifer from 6,000-9,500 ft (1829-2896 m); flowering August-September.

Distribution: New Mexico, Texas, and southeastern Arizona; Mexico.

Notes: This species looks very similar to Brickellia grandiflora, however, B. grandiflora has row of bracts around outer calyx (small bracts around the base of the involucre), while Brickelliastrum fendleri does not. Look for this species also under Brickellia fendleri.

Ethnobotany: Unknown

Etymology: Brickelliastrum is a derivative of Brickellia, but of uncertain provenance, while fendleri is named for Augustus Fendler (1813-1883).

Synonyms: Brickellia fendleri, Eriocarpum wootonii, Eupatorium fendleri, Steviopsis fendleri
