Plants perennial; taproot thick, fleshy; caudex branched. Stems 1-several, straggling to erect, sometimes decumbent at base, simple or much-branched distally, 20-120 cm, puberulent or scabrous-pubescent, sometimes retrorse, often glandular distally, becoming glabrate proximally. Leaves sessile or narrowed at base into pseudopetiole, blade pubescent on both surfaces; proximal with blade lanceolate and oblanceolate, broadest distally or distal often reduced, cauline longest near mid stem, blade linear to lanceolate or elliptic, 1.5-10 cm × 2-30 mm. Inflorescences from 1-flowered to simple dichotomy to compound and 3-5-many-flowered with elongate branches; bracts small, linear-lanceolate, or resembling leaves. Pedicels elongate, much exceeding calyx. Flowers: calyx green, 10-veined, broadly tubular, 12-25 × 4-8 mm in flower, narrower towards base, middle broadening to 6-13 mm in fruit, narrower at both ends, pubescent, glandular, lobes lanceolate, 2.5-5 mm, margins membranous or not, apex ± obtuse; corolla scarlet, clawed, claw equaling or longer than calyx, limb lobed, often deeply so, lobes 4-6, linear, lanceolate, or oblong, small lateral teeth may be present, 6-15 mm, appendages inconspicuous, 1-2 mm, dentate; stamens longer than corolla claw but shorter than lobes; stigmas 3, equaling corolla. Capsules oblong to ovoid or broadly tubular, equaling calyx, opening by 6 ascending teeth; carpophore 2-4 mm. Seeds reddish brown, broadly reniform, 1.7-2.3 mm, sides tuberculate, margins papillate.
Chaparral, oak woodlands, dry open woodlands, sea slopes, rocky hillsides and cliffs; at elevations up to 1,200 metres.
