LEAVES: simple, elliptic, ovate or lanceolate, 1-5 cm long, 0.5-2 cm wide, ca. 2 times as long as wide, submembranous, the margin entire or rarely with occasional teeth; apex acute to rounded; base rounded to oblique; petiole 5-15 mm long.

INFLORESCENCE: an umbel-like panicle with up to 6 flowers; peduncle 5-2 mm long.

FLOWERS: actinomorphic (Fig. 3I); pedicel 5-15 mm long; calyx up to 7 mm long and wide, campanulate, the lobes deltoid, shorter than the tube; corolla deep blue to lavender, 15-30 mm wide; stamens equal; anthers 4-5 mm long, not adherent, opening by ashort slit; filaments up to 1/3 as long as the anthers; style longer than the stamens.

FRUITS: 10-15 mm in diam., green, not enclosed by the calyx; seeds 1.5-2 mm in diam., numerous, yellowish brown, reniform.

NOTES: Rocky bajada slopes in chaparral: Coconino, Gila, Graham, Greenlee, Maricopa, Mohave, Navajo, Pima, Santa Cruz, Yavapai cos. (Fig. 2I); 1000-2100 m (3000-7000 ft); Apr-Nov; AZ, CA; Baja C., Mex. Native Americans of the central valley of California ate the berries raw (Ebeling, 1986).

Flowers: Umbelliform cymes on peduncles 5-12 mm long, densely glandular-villous, 4-9 flowered, on slender pedicels 5-15 mm long, villous with a larger proportion of hairs dendritic than in pubescence of twigs and leaves; calyx 4-6 mm deep, broadly deltoid lobes one third as long as or equaling broadly campanulate tube; calyx enlarging to 12 mm or less in diameter in fruit; corolla dark lavender to purple, 1.5-2.5 cm in diameter, finely puberulent outside, glabrous within, deltoid lobes, stamens equal or essentially so, filaments 1.5-2 mm long, glabrous; anthers yellow, erect, 3.2-4.8 mm long.

Notes: There is one variety in Arizona: var. xanti. This description is for that variety.

Ethnobotany: A poultice was applied to sores, to swollen leg and shoulder, and the raw berries were eaten.
