Habit | Perennials, rhizomatous, rooting at proximal nodes. | Annuals, fibrous-rooted, sometimes apparently rooting at proximal nodes if stems proximally decumbent. |
Stems | erect, sometimes ascending to decumbent, simple or branched, (2–)5–20 cm, nodes 2–4(or 5), glabrate to glandular-villous, hairs 0.5–2 mm, gland-tipped, internodes evident. |
erect, simple, 4-angled, 2–8 cm, slender, glabrous. |
Leaves | usually cauline, basal not persistent, distinctly separated; petiole 0 mm or (0.5–)1–5(–10) mm; blade pinnately veined, oblong-ovate to ovate, (10–)15–40(–50) × 5–25 mm, base obtuse-cuneate to truncate, rounded or subcordate, subclasping to sessile, margins coarsely serrate-dentate to denticulate or subentire, apex acute to obtuse, surfaces glabrate to glandular-villous. |
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, 1–8, from medial to distal nodes. |
plesiogamous, (1–)4–10, sometimes from all nodes, usually beginning about mid stem, cleistogamous. |
Styles | glabrous. |
glabrous. |
Corollas | yellow, throat with fine red to blackish or brown lines extending onto lobes, red to brown dots in throat and lobes present or absent, bilaterally or nearly radially symmetric, bilabiate or nearly regular; tube-throat narrowly funnelform, 11–18 mm, exserted beyond calyx margin; lobes oblong-obovate, apex rounded to notched. |
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. |
Fruiting pedicels | (7–)10–25 mm, glabrate to glandular-villous. |
usually deflexed 90º at calyx, 6–14 mm, longer than subtending leaves. |
Fruiting calyces | ridge- to wing-angled, campanulate to cylindric-campanulate, weakly or not inflated, 6–13 mm, villous to glandular-villous, lobes erect to spreading-recurving, strongly unequal to subequal, triangular to linear-lanceolate or narrowly triangular-acuminate, 2–4 mm, apex acute to obtuse. |
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 | Earlier segregation of Erythranthe moniliformis as distinct from E. moschata (for example, G. L. Nesom 2012g) emphasized a primarily erect habit and tendency toward sessile to subsessile and more densely arranged cauline leaves in E. moniliformis versus a decumbent to procumbent habit and consistently petiolate leaves on longer internodes in E. moschata. Discontinuities in morphology, geography, and ecology were not confirmed in later study by Nesom (2017). Rhizomes with small, tuberlike swellings can be observed over the whole moschata/moniliformis range, and there apparently are no consistent distinctions in vestiture and corolla size. Mimulus acutidens Reiche (1911), a later homonym of M. acutidens Greene, pertains here. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
