Herbs, annual. Stems erect, (10–) 20–180 mm, glandular-puberulent to short glandular-villous. Leaves usually cauline, relatively even-sized; petiole absent, base sometimes petiolelike; blade narrowly elliptic, sometimes broadly elliptic to obovate or oblanceolate, (2.5–) 6–20 (–26) × (1–) 2–10 (–14) mm, margins crenate to serrulate or entire, plane, apex rounded or acute, surfaces glandular-puberulent. Pedicels 2–7 (–10) mm in fruit. Flowers 2 per node, or 1 or 2 per node on 1 plant, chasmogamous. Calyces symmetrically attached to pedicels, not inflated in fruit, (5–) 7–8 mm, glandular-puberulent, lobes subequal, apex acute, ribs green, intercostal areas whitish. Corollas rose-pink to purplish, limb often pale, especially abaxial lip, abaxial lip often purple-dotted near base, markings often coalescing and forming broken lines radiating toward each lobe, tube yellow, palate ridges yellow with magenta speckling, confluent and extending onto abaxial lip base, tube-throat (8–) 11–12 mm, limb 7–12 mm diam., bilabiate. Anthers included, ciliate. Styles glandular-puberulent distally. Stigmas exserted, lobes subequal. Capsules 8–13 mm. 2n = 16.


Phenology: Flowering May–Aug.
Habitat: Bluffs, disturbed slopes, well-developed loam soils, vegetation openings.
Elevation: 500–1200(–2000) m.

Discussion

Diplacus clivicola is known from northern Idaho and immediately adjacent Montana and Oregon. It is similar to typical D. nanus in its strongly bilabiate corollas; it differs in its slightly toothed leaf blade margins, relatively long pedicels, and calyces with cuneate bases.
