Plants short-lived perennial, puberulent on stem and/or pedicels. Stems coarse, few to many from base, decumbent or rarely ascending, (6-)11-20(-30) cm, glabrous or puberulent along 1 line or throughout. Leaves simple or rarely deeply 3(or 5)-lobed apically; petiole somewhat flattened, 4-10(-18) mm; leaf blade broadly obovate or suborbicular and often wider than long, rarely oblong, (3-)6-10(-15) × (1.5-)4-10(-15) mm, glabrous, obscurely to prominently 3- or 5-toothed, teeth sometimes restricted to subtruncate apex, when lobed central lobe broadly to narrowly oblong, slightly broader than lateral lobes. Flowers often protogynous. Fruiting pedicels slender, strongly recurved or sigmoid, (0.7-)1.5-3(-4) cm, adaxially puberulent with papillae to 0.1 mm. Sepals oblong, glabrous, 2.5-3.5(-4) × 1-1.5 mm, margin membranous and to 0.5 mm wide, spreading, slightly saccate at base. Petals blue or deep purple, orbicular to orbicular-obovate, (5.5-)6-8(-9) × 4-6(-7) mm, apex rounded, base abruptly narrowed into a claw 0.5-1.5 mm. Filaments purple distally, whitish basally, 4-5.5 mm; anthers narrowly oblong, 0.6-1.2 mm, often strongly curved after dehiscence. Ovules 4-6(-11) per ovary. Fruit linear or narrowly oblong, rarely ovoid, not geocarpic, straight or curved, (5-)10-20 × 1.5-2 mm; gynophore ca. 0.5 mm; valves torulose; style 3-4 mm, stout. Seeds uniseriate, oblong, 2.2-2.8 × 1.2-1.4 mm. Fl. May-Jul, fr. Jun-Sep.
