Description: Low perennial shrub, to 30 cm (11.8 in.) tall, much branched from a woody caudex. Stems leafy, glabrous, dying back each year. Leaves 4 - 8 cm (1.6 - 3.1 in.) long, 10 - 25 mm (0.4 - 1.0 in.) wide, oblanceolate, entire, and nearly glabrous. Inflorescence congested with few discoid flower heads, to 8 mm (0.3 in.) tall. Phyllaries (bracts) 20 - 24, with green spots at tip. Ray florets absent; disk florets 5 - 6, yellow. Seed (achene) 3 mm (0.1 in.) long, covered with hairs. Time of flowering: August to September.
Habitat: Crevices or rubble of steep north-facing carbonate rock cliffs, in and just below the pinyon-juniper community. Elevations: 1,478 - 1,951 m (4,850 - 6,400 ft).
Range: Nevada endemic. Known only from the Sheep and Pintwater ranges, Clark and Lincoln counties, Nevada.
Comments: Similar to Charleston rabbitbrush (C. gramineous) in leaf and stems, but smaller flower heads (to 8 mm versus 17.5 mm), and keeled rather than unkeeled phyllaries. Leaves not resinous punctate.
