Cardamine gracilis (O. E. Schulz) T. Y. Cheo et R. C. Fang


Description from Flora of China

Cardamine multijuga Franchet var. gracilis O. E. Schulz, Repert. Spec. Nov. Regni Veg. 17: 289. 1921.

Herbs perennial, 10-35(-50) cm tall, glabrous throughout, semiaquatic. Rhizomes slender, to 10 cm or longer, 0.5-3 mm in diam. Stems erect, simple, striate angled, rooting from lower and sometimes middle nodes. Basal rosettes absent. Cauline leaves 10-20 per stem, (1.5-)2.5-7.5(-9) cm × (1.5-)4-14(-17) mm; petiole absent or rarely to 2 mm; terminal leaflet narrowly obovate, oblong, or rarely broadly ovate, (2-)3-8(-9) × (0.5-)1.5-5(-7) mm, petiolule 0.5-2 mm, base cuneate or rarely obtuse, margin obscurely 1-3-toothed on each side, apex acute, submucronate; lateral leaflets (6 or)7-12(-15) pairs, linear or narrowly oblong, asymmetric, slightly smaller than terminal lobe, sessile or rarely with a petiolule to 0.5 mm, base oblique, proximal margin 1- or 2(or 3)-toothed, distal margin entire or rarely obscurely 1- or 2-toothed, apex acute; proximal pair of lateral leaflets auriclelike, attached at or just above node, often giving appearance of amplexicaul leaf base. Racemes terminal, 10-20-flowered. Fruiting pedicels divaricate, 0.8-2.2 cm, slender. Sepals oblong or ovate, 3-4 × 1.2-2 mm, spreading, margin membranous, base of lateral pair subsaccate. Petals lavender with darker veins, spatulate, 6-8 × 2-3 mm, spreading, apex rounded. Filaments spreading, dilated at base, subequal, median pairs 3.5-5 mm, lateral pair 3-4.5 mm; anthers narrowly oblong, 1.3-1.6 mm. Ovules 10-14 per ovary. Fruit linear, 2-4 cm × ca. 1.5 mm; gynophore ca. 0.5 mm; valves smooth, glabrous; style 4-6 mm. Seeds brown, oblong, 1.7-2 × ca. 1.3 mm, winged all around; wing ca. 0.4 mm wide. Fl. Jun-Aug, fr. Jul-Oct.

This species, as Cardamine multijuga var. gracilis, was said to occur in Bhutan (Fl. Bhutan 1(2): 432. 1984), but the present authors have seen no material from that country. On the basis of having white flowers with smaller (4-6 mm) petals, it is likely that the record from Bhutan belongs to another species.

* Marshlands, lake shores, margins of ponds, ditches, open pastures; 2400-3300 m. Yunnan.
