Pistillate flowers: sepals lanceolate, 3–6.5 × 0.7–1.8 mm, without glands; petals 5, elliptic, 1.8–3 × 0.7–1.4 mm; nectary glands oblate, elliptic to ovate, 0.4–1 × 0.5–0.7 mm, glabrous, rarely pubescent; ovary strigose to hispidulous; styles 1.5–2 mm, glabrous; stigmas flattened. Capsules 3–5 mm, strigose to hispidulous. Seeds 1.8–2.5 mm, foveolate, striate.
Phenology: Flowering year-round.

Discussion
Argythamnia lanceolata is a common shrub of the Sonoran Desert and is easily recognized by its densely strigose, lanceolate to ovate, usually entire leaves, strongly flattened stigmas, and staminate flower petals adnate to the androphore. Plants from shady canyons tend to have broader and less hairy leaves.
