Densely branching from a woody root crown, these 4–18-inch tall  plants form rounded to flat-topped arrays covered with white flowers. Note the oblong, white petal-like ray flowers, and the erect, protruding yellow disk flowers, and narrow leaves with 1 vein.

FLOWER: April–October, especially after rains. The 4–7 white, petal-like ray flowers are oblong to rounded, 1/4–3/8-inch long (6–10 mm), and slightly drooping. The central disk has 8–13 tiny, yellow florets that fade to brown.

LEAVES: Opposite to crowded. Softly hairy branches have clusters of 2–3, narrow leaves 3/8–3/4-inch long (10–20 mm) by 1/16-inch wide (2 mm), with 1 vein at the base.

HABITAT: Rocky, sandy soils; desert grasslands and scrub.

ELEVATION: 3,500-6,000 feet.

RANGE: AZ, NM, TX.
