Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Perennials, rhizomatous, sometimes rooting at nodes, mat-forming. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
procumbent, branched, 5–20 cm, glabrous. |
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. |
cauline; petiole 2–10(–20) mm; blade palmately 3–5(–7)-veined, ovate to broadly ovate or orbicular-ovate, 4–15(–22) × 4–15(–18) mm, base truncate to cuneate, margins shallowly denticulate or merely mucronate to mucronulate, teeth 3–6 per side, apex acute to obtuse, surfaces glabrous, adaxial sometimes moderately villosulous, hairs vitreous, flattened, eglandular or minutely gland-tipped. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
plesiogamous, 2–8, axillary at distal nodes. |
Styles | minutely hirtellous-puberulent. |

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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erythranthe chinatiensis is similar to E. parvula in its prostrate habit, five-lobed calyces, and fimbriate corolla lobes. It differs from the latter in its nearly glabrous leaves and strongly reflexed abaxial corolla lip. Erythranthe chinatiensis is known only from Presidio County but should be expected to occur also in adjacent Chihuahua, Mexico.
