Erythranthe norrisii

Erythranthe hallii

Kaweah monkeyflower, Norris' monkeyflower

Hall's monkeyflower
Habit Annuals, fibrous-rooted or filiform-taprooted. Annuals, fibrous-rooted, sometimes apparently rooting at proximal nodes if stems proximally decumbent.
Stems

ascending to erect-ascending, geniculate at nodes, usually branched from proximal nodes, 2–15(–25) cm, villous-glandular.

basal and cauline;

petiole 5–10(–15) mm;

blade palmately 3–5-veined, sometimes with 1–3 distal vein pairs diverging pinnately, elliptic to elliptic-obovate, 20–35 × 10–20 mm, base usually attenuate, margins subentire to distally denticulate, apex acute to obtuse, surfaces villous-glandular.

basal and cauline or basal deciduous, largest at mid stem or above, cauline relatively few on long internodes;

petiole: basal and proximals to midcauline 1–4 mm, distals 0 mm;

blade palmately 3-veined, ovate to ovate-lanceolate, 5–11 × 3–9 mm, base truncate to cuneate, margins very shallowly dentate or denticulate, apex acute to obtuse, surfaces glabrous or distals and bracteals sparsely villous, hairs vitreous, flattened, eglandular, multicellular.
Flowers

herkogamous, 1–5, from medial to distal nodes.

plesiogamous, (1–)4–10, sometimes from all nodes, usually beginning about mid stem, cleistogamous.
Styles

glabrous.
Corollas

yellow, base of each lobe with a prominent maroon splotch, abaxial limb with white patch at 2 sinus bases, weakly bilaterally or radially symmetric, weakly bilabiate or regular;

tube-throat cylindric-funnelform, 12–16 mm, exserted beyond calyx margin;

limb expanded 15–30 mm, lobes oblong-obovate to orbicular-obovate, apex rounded-truncate.

yellow, usually red-dotted, bilaterally or nearly radially symmetric, bilabiate or nearly regular;

tube-throat narrowly cylindric, 4–6 mm, exserted 0.5–1 mm beyond calyx margin;

limb barely expanded.

20–35(–50) mm, villous-glandular.

usually deflexed 90º at calyx, 6–14 mm, longer than subtending leaves.
Fruiting calyces

red-dotted, campanulate, weakly inflated, 4–6 mm, margins distinctly toothed or lobed, villous-glandular, ribs rounded-thickened, lobes pronounced, erect, often incurved, linear-oblong to oblong-lanceolate, apex rounded to blunt.

sometimes red-dotted, broadly elliptic-ovoid, inflated, sagittally compressed, (5–)7–10 mm, glabrous, throat closing, adaxial lobe not distinctly longer than abaxial, not falcate.

Discussion

Erythranthe norrisii is known only from the Kaweah River drainage; most populations are in Sequoia National Park in Tulare County. The species is characterized by its short-petiolate leaves with attenuate bases, very large corollas with red splotches at the base of each lobe and two white patches on the abaxial limb, and very short, purple-dotted calyces with rounded-thickened ribs and linear-oblong lobes incurved in fruit. The capsules often are slightly exserted.

Erythranthe hallii is known from Boulder, Clear Creek, Fremont, Grand, Jefferson, Larimer, Routt, and Saguache counties. The Colorado population system is morphologically and geographically coherent.

Erythranthe hallii is similar to E. arvensis; both have four-angled stems, autogamous reproduction, a tendency to root at basal nodes and distally, and both have bracteal leaves villous with vitreous, flattened, eglandular, multicellular hairs, although this vestiture is barely developed and often absent in E. hallii. The only reported chromosome number from the Colorado plants (2n = 32) also appears to be distinct among possible relatives of E. hallii.
