coralline monkeyflower

Habit Annuals, shallowly fibrous-rooted. Perennials, rhizomatous, rhizomes often forming a mass, usually branching, filiform.
Stems

ascending, geniculate at nodes, branched at proximal and medial nodes, 4–15 cm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular.

usually erect to ascending-erect, few-branched, 6–25(–38) cm, moderately hirsute to hirtellous, hairs deflexed.

Leaves

usually cauline, basal usually deciduous by flowering;

petiole 1–3 mm;

blade palmately 3-veined, narrowly ovate or narrowly lanceolate to elliptic or elliptic-lanceolate, largest 5–15 × 2–6 mm, relatively even-sized, or slightly reduced distally, base attenuate, margins entire, mucronulate, or denticulate, apex acute to obtuse, surfaces minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular.

basal and cauline, becoming larger distally or even-sized;

petiole 0 mm or proximals 1–15 mm;

blade palmately 5-veined, ovate to broadly ovate, 15–45 mm, base mostly truncate to shallowly cordate, margins sharply dentate-serrate, apex obtuse, surfaces hirtellous to softly hirsute, hairs ascending, straight, dull gray, sharp-pointed, thick-walled, eglandular.

Flowers

plesiogamous, 10–20, from medial to distal nodes.

herkogamous, 1–3(–6), commonly solitary or from distal nodes.

Styles

glabrous.

sparsely hirtellous.

Corollas

yellow, red-spotted or striped, bilaterally symmetric, weakly bilabiate;

tube-throat cylindric to narrowly funnelform, 3.5–5 mm, not exserted beyond calyx margin;

limb barely widened, lobes broadly obovate, apex rounded.

yellow, red-spotted, bilaterally symmetric, bilabiate;

tube-throat narrowly funnelform to broadly cylindric, 13–20 mm, exserted beyond calyx margin;

limb expanded 12–22 mm.

Fruiting pedicels

straight, 5–11 mm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular.

(10–)25–75 mm, glabrous or puberulent proximally, hairs stipitate-glandular.

Fruiting calyces

winged, plicate-angled, campanulate becoming ovoid-ellipsoid to campanulate, distinctly inflated, 5–6 mm, margins distinctly toothed or lobed, sparsely, minutely hirtellous, eglandular, sometimes sparsely sessile-glandular, lobes pronounced, erect.

sometimes purple-spotted, broadly cylindric-campanulate, inflated, sagittally compressed, 11–15 mm, glabrous, throat not closing, proximal lobe pair slightly upcurving.

Capsules

included, 4–6 mm.

included, stipitate, 7–10 mm.

Discussion

Erythranthe corallina is a morphologically consistent entity that occurs only in the Sierra Nevada of California and adjacent Nevada (Washoe County and Carson City). Its chromosome number is reported as 2n = 48 and 56, compared to 2n = 28 and 56 in E. tilingii; identities of the E. corallina vouchers should be rechecked and additional counts made, since the occurrence of such wide dysploidy seems unlikely. Compared to the leaf blades of E. tilingii in the strict sense, those of E. corallina are relatively broader (broadly ovate to orbicular-ovate), the plants generally taller, and long-pedicellate flowers occasionally are produced from mid stem or even proximal nodes. The hirsutulous to hirsute vestiture of eglandular hairs on both leaf surfaces is a reliably diagnostic feature and usually easily observed with a 10× lens.

Some plants of Erythranthe corallina from San Bernardino County, California, produce decumbent-ascending stems (4–10 cm) and ovate-triangular leaves (blade 5–10 × 3–6 mm), but the dense system of filiform rhizomes, flowers one to three, and hirtellous foliar vestiture serve to identify them.
