Herbs, annual. Stems erect, (10–)20–180 mm, glandular-puberulent to short glandular-villous. Leaves usually cauline, relatively even-sized; petiole absent, base sometimes petiole-like; 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.

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.

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.
