Perennials, rhizomatous, sometimes rooting at nodes, mat-forming. Stems procumbent, branched, 5–20 cm, glabrous. Leaves 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 plesiogamous, 2–8, axillary at distal nodes. Fruiting pedicels 10–20 mm, glabrous. Fruiting calyces nodding 45–90º, 5-lobed, ellipsoid, inflated, sagittally compressed, 5–6 mm, glabrous or sparsely villosulous-glandular, throat closing. Corollas yellow, red-dotted, bilaterally symmetric, bilabiate; tube-throat funnelform, 7–8 mm, exserted beyond calyx margin; limb expanded 6–7 mm, abaxial limb strongly reflexed, lobes fimbriate. Styles glabrous. Anthers included, glabrous. Capsules included, 4–5 mm.


Phenology: Flowering Feb–Sep.
Habitat: Seeps in vertical cliff faces, wet bluffs.
Elevation: 600–1900(–2300) m.

Discussion

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.
