PLANT: Annual, 9-30(-35) cm tall, simple or branched above rosette, glabrous and glaucous below, glandular above.

LEAVES: cobwebby pubescent on upper surface, abruptly reduced above the basal rosette; basal deeply lobed once, the lobes oblong; cauline clasping, dentate to entire.

INFLORESCENCE: open, with 1-3 short pedicelled flowers at branch tips.

FLOWERS: calyx 3-5 mm long, glandular, thelobes short acuminate; corolla funnelform, 7-12 mm long, the tube exserted, purple and whitestriate, the throat yellow or purple tinged below, the lobes white to lavender; stamens insertedon the throat; anthers exserted; stigmas located among or slightly above the anthers.

CAPSULE: 4-7 mm long, ovoid. 2n=36.

Duration: Annual

Nativity: Native

Lifeform: Forb/Herb

General: Annual herbs, 10-35 cm tall; stems unbranched or branched above the basal rosette, glabrous and glaucous (slightly waxy) near the base, the upper stems covered with amber-colored stipitate glands.

Leaves: Basal rosette plus a few reduced, alternate stem leaves, all sparsely cobwebby on the upper surfaces; basal leaves deeply divided into oblong lobes; stem leaves dentate or entire, with clasping bases.

Flowers: Purple, white, and yellow, arranged in open panicles with 1-3 short-pedicelled flowers at the tip of each branch; calyx 3-5 mm long, consisting of 5 herbaceous sepals connected to each other by papery membranes, the sepals short-acuminate and usually covered with gland-tipped hairs; corolla funnelform, 7-12 mm long, the tube portion of the corolla longer than the sepals and purple-and-white-striate, the corolla throat yellow or purple-tinged below, and the corolla lobes white to lavender; anthers exserted beyond the corolla.

Fruits: Capsules 4-7 mm long, ovoid; containing several seeds.

Ecology: Found in sandy soils, shrublands, and woodlands from, 1,000-6,000 ft (305-1829 m); flowers March-May.

Distribution: B.C., WA, and ID, south to CA, AZ, and NM; south to n MEX.

Notes: This delicate annual Gilia is quite similar to G. mexicana and G. flavocinta. Distinguish it based on its stem leaves with bases that clasp the stem; the mostly hairless lower portions of the plant, with sparse cobwebby hairs on leaf tops and at lower leaf axils only (G. flavocinta and G. mexicana are more copiously cobwebby); the rachises (center stalks) of basal leaves which are wide, flat, and strap-like; the copiously glandular upper stems, particularly near the flowers; and the usually glandular sepals. Glands are usually amber-colored and on short stalks.

Ethnobotany: The Hualapai parched and ground the seeds into seed butter.

Etymology: Gilia is named for Filippo Luigi Gilii (1756-1821) an Italian naturalist, while sinuata means having sinuous or wavy margins.

Synonyms: Gilia inconspicua var. sinuata
