Description from Flora of China

Cardamine griffithii J. D. Hooker & Thomson subsp. multijuga (Franchet) O. E. Schulz.

Herbs perennial, (20-)40-100(-160) cm tall, glabrous throughout. Rhizomes creeping, without stolons. Stems erect, simple or branched above, rooting from lowermost nodes, striate angled, 11-25-leaved. Leaves sessile, cauline; lower and middle ones 2.2-6(-10) cm; terminal leaflet orbicular or broadly obovate, 3-12 × 3-11 mm, with a petiolule 0.5-6 mm, base subcordate or cuneate, margin repand and not ciliate, apex obtuse or rounded; lateral leaflets (7 or)8-11(-15) pairs, slightly smaller than terminal one, ovate or ovate-oblong, base obtuse, margin repand and not ciliate, apex obtuse or rounded; proximal pair of lateral leaflets auriclelike, attached at or just above node, often giving appearance of amplexicaul leaf base. Uppermost leaves smaller. Fruiting pedicels divaricate, 1-2 cm, slender, straight. Sepals oblong, 2.5-3 × 1.5-2 mm, spreading. Petals purple or lavender, obovate, 7-9 × 3-4 mm, not clawed, apex rounded. Filaments spreading, subequal, 4-5 mm; anthers narrowly oblong, 1.5-1.7 mm. Ovules 10-16 per ovary. Young fruit glabrous; styles 2-4 mm; stigma entire. Immature seeds wingless. Fl. Jun-Jul.

Cardamine multijuga, which was previously reduced to the synonymy of C. griffithii, is known only from older collections. However, it is readily distinguished from C. griffithii by having cauline leaves with (7 or)8-11(-15) pairs of nonciliate lateral leaflets, spreading sepals, petals, and stamens, subequal stamens, entire stigmas, and styles 3-4 mm. By contrast, C. griffithii has cauline leaves with 2-4(or 5) pairs of ciliate lateral leaflets, erect sepals, petals, and stamens, tetradynamous stamens, strongly 2-lobed stigmas, and styles 0.5-1(-2) mm.

* Streamsides, marshy places; 200-2800 m. Yunnan.
