Subshrubs. Stems erect, 300–800 (–1200) mm, minutely hirtellous to hirsutulous with slightly deflexed, eglandular hairs. Leaves cauline, relatively even-sized; petiole absent; blade narrowly elliptic to narrowly lanceolate or narrowly elliptic-oblong, 12–37 × 3–9 mm, margins entire, serrulate, or mucronulate, plane or revolute, apex usually obtuse to rounded, surfaces glabrous. Pedicels 3–10 mm in fruit. Flowers (1 or) 2 per node, chasmogamous. Calyces not inflated in fruit, 20–28 mm, glabrous, tube slightly dilated distally, lobes unequal to subequal, apex acute. Corollas yellow-orange to dull orange, not spotted or striped, palate ridges yellow, tube-throat 35–45 mm, limb 20–25 mm diam., bilabiate, lobes oblong, each apically incised 1/4–1/2 length, appearing 2-lobed. Anthers included, glabrous. Styles minutely glandular. Stigmas included, lobes equal. Capsules 18–30 mm. 2n = 20.


Phenology: Flowering Apr–Jun.
Habitat: Dry hillsides, rock outcrops.
Elevation: 100–300 m.

Discussion

The coastal Diplacus linearis (as Mimulus bifidus subsp. fasciculatus) was allied by F. W. Pennell (1947) with the Sierran D. grandiflorus (as M. bifidus subsp. typicus) as a narrower-leaved and smaller-flowered subspecies; see discussion concerning its distribution under 40. D. grandiflorus. The two were considered synonymous by D. M. Thompson (2005). They are distinct in geography, ecology, and morphology.
