Herbs strigillose, often densely so, sometimes also glandular puberulent distally. Stems 5–40 cm. Leaves: blade lateral lobes poorly or well developed, terminal lobe lanceolate, to 6.5 × 2 cm, margins irregularly sinuate-dentate. Flowers opening at sunset; buds usually without free tips, sometimes with apical free tips less than 1 mm; floral-tube orangebrown inside, 2.5–4 mm; petals pale-yellow, fading reddish or not changing color, 3–5 mm. 2n = 14.


Phenology: Flowering Feb–May.
Habitat: Very arid dunes and sandy flats, with Ambrosia dumosa and Larrea tridentata.
Elevation: 0–300 m.

Distribution

Ariz., Calif., Mexico (Baja California), Mexico (Sonora)

Discussion

Subspecies yumae is known from southeastern Imperial County, California, Yuma Desert, Arizona, and from El Gran Desierto to Puerto Peñasco in north­western Sonora, and in northeastern Baja California. The subspecies is probably from hybridization between subspp. aurantiaca and peirsonii; it intergrades with subsp. aurantiaca and rarely hybridizes with Chylismia brevipes subsp. arizonica.
