Herbs, annual. Stems erect, (25–) 50–800 (–1000) mm, usually glandular-puberulent or glandular-pubescent, viscid. Leaves basal and cauline, basal usually in rosette, cauline gradually reduced distally; petiole often present proximally, usually absent distally; blade linear-lanceolate, elliptic, narrowly oblanceolate, or lanceolate, sometimes ovate or obovate, 7–90 (–125) × 1–40 (–48) mm, margins serrate or entire, plane, apex rounded to acute, surfaces: proximals glabrate, distals glandular-puberulent or glandular-pubescent. Pedicels 2–10 (–17 at proximalmost node) mm in fruit. Flowers 2 per node, or 1 or 2 per node on 1 plant, chasmogamous. Calyces inflated in fruit, (7–) 10–25 (–31) mm, glandular-pubescent and viscid, lobes unequal, apex acute to acuminate, ribs green, sometimes purplish, intercostal areas white. Corollas yellow, usually with reddish-brown spots, palate ridges yellow, tube-throat (10–) 15–30 (–34) mm, limb 11–30 mm diam., not bilabiate. Anthers included, glabrous. Styles glandular-puberulent. Stigmas included, lobe unequal, abaxial 1.5–2 times adaxial. Capsules (7–) 8–14 (–17) mm. 2n = 16.


Phenology: Flowering Apr–Jul.
Habitat: Openings in chaparral or coastal sage scrub, recently burned or mechanically disturbed areas.
Elevation: 30–1800(–2200) m.
