simple, 8–35 cm.

erect, leafy, 8–85 cm, stipitate-glandular.

in basal rosette and cauline, basal 3-lobed, (segments 3–4-lobed, round), cauline (2–4), 3-lobed or -foliolate, much reduced, similar to basal, (segments or leaflets simple or 1–3-lobed, often with axillary bulbils);

stipules large, not decurrent on petiole, (margins fimbriate);

petiole 1–4(–8) cm;

blade green, orbiculate, base cordate, surfaces nearly glabrous or sparingly hairy.

in basal rosette and cauline;

cauline leaves (1–)2(–10), usually alternate (opposite in L. cymbalaria), unlobed, lobed, or palmately compound, sometimes with bulbils in axils;

stipules present;

petiole stipitate-glandular;

blade rhombic or orbiculate to reniform, lobed, base cordate, hastate, rounded, ligulate, or cuneate, ultimate margins entire or toothed, apex obtuse or acute, surfaces often stipitate-glandular;

venation palmate.

solitary flowers or erect, 2–5(–7)-flowered racemes, often appearing corymbose, rarely branched unless plant with bulbils, (8–20 cm, flowers sometimes replaced with bulbils).

compact or lax racemes, arising from axillary buds in basal rosette, 2–12(–25)-flowered, sometimes flowers solitary, (flowers sometimes replaced by bulbils), bracteate.

to 3–4 times length of hypanthium, (flowers long-pedicellate).

persistent, not fragrant, horizontal;

hypanthium narrowly campanulate with acute or hemispheric base, elongating slightly in fruit, throat open, (length 2 times diam.);

sepals erect in bud, widely spreading after anthesis, triangular;

petals (completely exserted), widely spreading, usually pink, rarely white, ovate, narrowly clawed, deeply and palmately 5-lobed, (without serrations at base, sinuses extending 4/5+ to base of lamina), 3.5–7 mm, ultimate margins entire;

ovary to 1/2 inferior;

styles slightly exserted in fruit;

stigma papillae apical.

hypanthium partially adnate to proximal 1/2 to entire length of ovary, free from ovary 1–2 mm, green;

sepals 5, green tinged with red;

petals 5, white or pink; nectariferous tissue inconspicuous;

stamens 10, (inserted on hypanthium, inner whorl attached proximal to point of petal insertion);

filaments filiform; (anthers cordate);
