Shrubs prostrate to erect, 0.1–2 m; bark yellowish to gray; stems glabrous. Leaves: blade spheric to spatulate, 2–25 × 1–3 mm, fleshy to succulent, surfaces glabrous. Inflorescences 2–3-flowered fascicles or solitary flowers. Pedicels 1–5 mm. Flowers bisexual or pistillate, 4-merous; calyx campanulate, 2–4-lobed, 2–3 mm, lobe lengths 0.3 times tube; corolla white to pale purple, campanulate, 2–6 mm, lobe lengths to 1 times tube; stamens exserted (bisexual flowers) or included, with nonfunctional anthers (pistillate flowers). Berries orange to red, ovoid, 2–6 mm, thinly fleshy. Seeds 2, each enclosed by a hard layer. 2n = 24, 36, 48.
Phenology: Flowering Jan–Mar(–Sep).

Discussion
Within the flora area, Lycium californicum occurs in southern Arizona and southwestern California. Populations of L. californicum vary in both ploidy (diploid to tetraploid) and sexual system (hermaphroditic to gender dimorphic). Gender dimorphic populations are morphologically gynodioecious (functionally dioecious), and plants are sexually dimorphic for flower size, with smaller pistillate flowers.
