    Erect to procumbent annual or perennial; stems 20–50(–75) cm. long, often rooting at the lower nodes, glabrous.
    Leaves
    Leaves spirally arranged, generally with a slender petiole (1–)1.5–5(–6.3) cm. long; lamina ovate to ovate-lanceolate, to broadly elliptical or elliptic-oblanceolate, 2.8–9(–10) cm. long, 1–4(–5.2) cm. broad, often membranous, the apex subacute, acuminate or cuspidate, the tip 4–15 mm. long, 2–5 mm. broad, the base cuneate, sparsely pubescent or glabrous on both surfaces; lateral veins 4–9 pairs; margin crenate or crenate-dentate or ± crenulate, usually with a few 1–2 mm. long fimbriae towards the base.
    Flowers
    Flowers axillary, solitary or in fascicles of 2–3(–4), sometimes on a reduced ± 1–3 mm. long peduncle, whitish, pale pink or pale mauve, often with a small white or pale yellow dot towards the base of the lateral united petals.
    Bracts
    Bracts subulate, 1–2 mm. long, inconspicuous.
    Pedicel
    Pedicels 0.8–4.2 cm. long, slender, glabrous.
    Calyx
    Lateral sepals ovate-lanceolate, 1.5–4 mm. long, acute, glabrous. Lower sepal shallowly navicular, 5–8 mm. long, abruptly constricted into a (10–) 16–34 mm. long curved filiform spur, often slightly thickened at the tip.
    Corolla
    Dorsal petal 6–7 mm. long, 6–7 mm. broad (when flattened), shallowly cucullate, dorsally with a narrow crest. Lateral united petals 8–19 mm. long; upper petal narrowly oblong to obovate, 2–6 mm. long, 1.5–5 mm. broad, sometimes ± obsolete, entire or emarginate; lower petal broadly elliptic, oblong or suborbicular, 4.5–11 (–12) mm. long, 6–8 mm. broad, distally and along the inner margin prolonged into a 3–8 × 1–3 mm. ligulate appendage, obtuse or subacute at the tip.
    Ovary
    Ovary glabrous.

    Habit
    Erect or straggling perennial (always?) herb; stems 20–60 (75) cm. high, usually glabrous.
    Leaves
    Leaves spirally arranged, petiolate; lamina (3) 4–8·5 (11) × (2) 2·5–4 (5) cm., ovate-lanceolate to narrowly elliptic or elliptic-lanceolate, membranous, sparsely pilose on both surfaces or glabrous; secondary nerves 8 (10) pairs, some what prominent beneath, apex subacute or rarely obtuse, usually acuminate, margin crenulate-denticulate (the teeth usually in the sinuses), base cuneate; petiole (1) 1·5–4 (5) cm. long, rather slender, pilose or glabrous.
    Flowers
    Flowers axillary, solitary or in few-flowered clusters, usually very pale pink, white on the back with two spots at the base of the posterior sepal; bracts very small, lanceolate-triangular or subulate, acute; pedicels 2–3·5 (4·5) cm. long, very slender, usually glabrous.
    Calyx
    Lateral sepals 2–3 (4) × 0·75–1·5 (1·75) mm., lanceolate to triangular, acute, usually glabrous; posterior sepal (4) 5–6 (7) mm. long, shallowly navicular, abruptly constricted into the spur, distally subcaudate, glabrous or very sparsely pilose; spur (8) 10–18 (25) mm. long, slightly incurved, rather slender, subconical, tapering into a subacute or sometimes slightly thickened end, usually glabrous, rarely sparsely pilose.
    Corolla
    Anterior petal 5–7·5 mm. high, 4·5–8 mm. broad when flattened, with a distinct dorsal crest, apically apiculate; lateral united petals 10–17 mm. long, 2-lobed but the lobes very dissimilar in shape and size; anterior lobe variable in shape and size, 8–13 mm. long (at the base) and 6–10 mm. high, broadly transverse-elliptic, broadly obovate to subcircular, distally prolonged at the very base into a ligulate appendage 2–7 × 1–2 (3) mm.; posterior lobe reduced to a small auricle not exceeding 2 × 2 mm. (see t. 26 fig. 19).
    Ovary
    Ovary glabrous or rarely scattered-hispid.
    Fruits
    Capsule 6–13 mm. long, fusiform, glabrous or scattered-hispid.
