Erythranthe glaucescens
Phytoneuron 2012-39: 43. 2012.
Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. Stems erect, simple or branched, terete, sometimes 4-angled distally, (5–) 30–60 (–80) cm, glabrous, glaucous. Leaves basal and cauline; petiole: basal and proximal cauline as long as or much longer than blade, slender, sometimes pubescent or villous, distals absent; blade palmately 3–5-veined, (proximal) ovate to ovate-elliptic or orbicular-ovate, sometimes subcordate, 10–50 mm, midcauline to distal orbicular, 5–45 mm wide, distinctly connate-perfoliate, disclike distally, base rounded to subcordate, margins: proximals denticulate to dentate or coarsely, irregularly toothed, sometimes lobed at base, distals nearly entire or toothed, teeth scattered, small, apex rounded, surfaces glabrous, glaucous. Flowers herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. Fruiting pedicels 10–50 mm, glabrous, glaucous. Fruiting calyces broadly campanulate, inflated, sagittally compressed, 7–16 mm, glabrous, glaucous, throat closing. Corollas yellow, sometimes with a median splotch, abaxial limb densely dark yellow, others much lighter, throat floor and tube red-dotted, bilaterally symmetric, bilabiate; tube-throat funnelform, 12–23 mm, exserted 4–8 mm beyond calyx margin; limb expanded 14–36 mm. Styles minutely hirtellous-puberulent. Anthers included, glabrous. Capsules included, 5–11 mm. 2n = 28.
Phenology: Flowering Mar–May(–Jun).
Habitat: Seepage areas, wet rocks, moist cliffs, pool edges, gravelly stream banks, serpentine outcrops, roadsides and roadcuts, low pastures, riparian woodlands, blue oak woodlands, chaparral, grasslands.
Elevation: 80–900(–1100) m.
Discussion
Plants from one locality in Butte County are unusual in producing filiform, small-leaved runners from basal cauline nodes. Erythranthe glaucescens is known only from Butte and Tehama counties.
