Habit | Annuals, fibrous-rooted or filiform-taprooted. | Annuals, taprooted or fibrous-rooted. |
Stems | ascending to ascending-erect, geniculate at nodes, usually many-branched from base, 3–10(–25) cm, short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped. |

Leaves | basal and cauline, largest at base or near mid stem, sometimes unreduced in size up to distalmost nodes; petiole 0 mm; cauline blade palmately 3(–5)-veined, ovate to ovate-lanceolate, 8–26(–35) mm, base abruptly cuneate to rounded, sometimes subauriculate, margins entire or barely mucronulate to shallowly dentate-mucronulate, teeth or mucronulae 1–3 per side, apex acute to rounded, surfaces short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped. |
cauline on wide internodes; petiole 5–30 mm, distals 0 mm; blade 1-veined or palmately 3–5-veined, proximals lanceolate or oblong-lanceolate to ovate, narrowly spatulate, or oblanceolate, distals usually linear, not perfoliate, 5–15(–30) × 1–5 mm, base attenuate, margins denticulate to proximally dentate-lobed, apex acute, surfaces glabrous or minutely stipitate-glandular, hairs 0.05–0.1 mm, at least just above nodes. |
Flowers | plesiogamous, (1–)3–12, from medial to distal nodes. |
herkogamous, (2–)4–8, usually in proximal or medial to distal axils, chasmogamous. |

Discussion | The distinction between Erythranthe latidens and E. inflatula sometimes seems arbitrary, perhaps because of gene exchange where they are sympatric in northwestern California. Erythranthe latidens in Oregon is known only from southern Harney County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erythranthe nudata is distinct in its annual duration, few, inconspicuous, and narrow leaves, long and spreading-divaricate pedicels, and large corollas. The plants apparently are restricted to serpentine substrate and known only from Colusa, Glenn, Lake, Mendocino, Napa, and Sonoma counties.
