Cardamine fragariifolia O. E. Schulz

The above first record from Myanmar is based on Maw Mu Pa 17432 (K).

Records of Cardamine trifoliolata J. D. Hooker & Thomson in FRPS, Fl. Sichuan. (14: 89. 1999), Fl. Xizang. (2: 360. 1985), and Fl. Yunnan. (6: 58. 1995) are all based on misidentified plants of C. fragariifolia. The former species, which also occurs in China (see below), is readily distinguished by being a slender plant, 5-20(-30) cm tall, with white flowers, few cauline leaves, and a repand or obtusely lobed terminal leaflet 0.5-1(-1.5) cm. By contrast, C. fragariifolia is a robust plant, (35-)50-100(-130) cm tall, with purple, lavender, or pink (rarely white) flowers, (5-)7-10(-15) cauline leaves, and a serrate to crenate terminal leaflet (1.5-)3-8(-12) cm.

Herbs perennial, (35-)50-100(-130) cm tall. Rhizomes 3-8 mm in diam. Stems erect, simple or branched above, glabrous or rarely puberulent. Basal leaves withered by flowering. Cauline leaves (5-)7-10(-15), petiolate, trifolioate, rarely lowermost with 4 or 5 leaflets, often simple below raceme; petiole 1-6(-10) cm, not auriculate at base, wingless or wing rarely to 1 mm wide; petiolules 1-6(-11) mm; leaflets subequal or terminal larger, ovate or lanceolate, rarely elliptic or subrhomboid, (1.5-)3-8(-12) × (1-)2-3(-5) cm, glabrous or with appressed, antrorse, simple trichomes 0.1-0.7 mm, base cuneate or obtuse, that of lateral leaflets often oblique, margin serrate or crenate, rarely lobed or subentire, ciliate with trichomes more than 0.1 mm, teeth mucronate, apex acute, acuminate, or acuminate-caudate. Fruiting pedicels divaricate, 5-9(-13) mm, slender, straight, glabrous or sparsely puberulent. Sepals oblong, 2.5-3.5(-4) × 1.5-2 mm, erect or ascending, not saccate, glabrous. Petals purple, lavender, pink, or rarely white, obovate or obovate-oblong, (6-)7-9(-10) × (2.5-)3-4 mm, rounded at apex; claw 1.5-2(-3) mm. Median filament pairs 4-5 mm, lateral pair 3-4 mm; anthers (0.6-)0.7-1 mm. Pistil glabrous; style slender, ca. 1 mm; stigma entire. Fruit and not seen. Fl. May-Jul.
