Cardamine flagellifera

Perennials; hirsute or pilose proximally, sparsely pubescent or glabrous distally. Rhizomes swollen, compact at stem base, (fleshy, stolons many, slender, ca. 1 mm diam., pubescent or glabrous). Stems erect, usually unbranched, rarely branched distally, 1–2.5 dm, sparsely to densely hirsute or pilose proximally, sparsely so or glabrous distally. Rhizomal leaves usually simple, rarely 3-foliolate, (3–)6–16 cm, leaflets petiolulate or subsessile; petiole (1.5–)4–13 cm; lateral leaflets subsessile or petiolulate (to 0.5 cm), blade similar to terminal, much smaller; terminal leaflet (petiolule 0.5–2 cm), blade orbicular to reniform or broadly ovate, (1–)1.5–4.5 cm, base cordate, margins repand to coarsely crenate, (apiculate at vein endings, surfaces sparsely pubescent or glabrous). Cauline leaves 2–5, 3 or 5-foliolate, petiolate, leaflets petiolulate or subsessile; petiole 0.8–5 cm, base not auriculate; lateral leaflets sessile or petiolulate (to 0.5 cm), blade similar to terminal, smaller; terminal leaflet petiolulate (0.5–1.5 cm), blade broadly ovate to suborbicular, 1.5–4(–5) cm × 12–35 mm, margins repand to coarsely crenate or slightly lobed, (apiculate at vein endings, margins glabrous). Racemes ebracteate. Fruiting pedicels ascending to divaricate-ascending, 7–20 mm. Flowers: sepals (ascending) oblong, 3–3.5 × 1–1.5 mm, lateral pair not saccate basally; petals white, oblanceolate, 5–6.5(–8) × 1.5–2.5 mm, (not clawed, apex obtuse to subemarginate); filaments: median pairs 3.5–5 mm, lateral pair 2.5–3 mm; anthers oblong, 1.2–1.6 mm. Fruits linear, 1.5–2.5 cm × 1–1.2 mm; ovules 10–14 per ovary; style 1.2–2.5 mm. Seeds brown, oblong, 1.2–1.7 × 0.8–1.1 mm.
