Perennial herb, single rosette or multiple rosettes on short lateral branches, stem and branches 1.0–2.0 mm diam. Leaves up to 60 mm long, usually simple or occasionally pinnatifid with up to 4 lobes; lamina 3.0–20.0 × 2.4–12.5 mm, green, glabrous or hairy, coriaceous, obovate, elliptic to broadly elliptic, sinuate, margin entire; apex obtuse to subacute, hydathode obscure or absent; base cuneate; petiole up to 32 mm long, plano-convex, glabrous or hairy. Cauline leaves sometimes present, subtending corymbs or individual flowers or inserted on pedicel, similar to rosette leaves. Inflorescence corymbose, with 1–4 corymbs each 4–16-flowered, with flowers clustered toward distal end; peduncle 7–110 mm long, 1.0–2.5 mm diam. at base, ascending to erect, glabrous. Pedicels 2.5–25.0 mm long, 0.4–0.6 mm diam., stout, glabrous. Sepals 1.8–2.5 × 0.9–1.1 mm, elliptic-oblong to elliptic, ± saccate, green and sometimes flushed red-brown at apex, glabrous or hairy, margin white and membranous, apex obtuse, base truncate. Petals 1.5–2.7 × 0.6–1.3 mm, white, limb obovate to broadly obovate; apex obtuse; base cuneate, tapering to a 0.7–1.0 mm-long claw. Stamens 6; median filaments 4, 1.8–2.6 mm long; lateral filaments 2, 1.6–2.2 mm long; anthers 0.5–0.6 mm long, cream to pale yellow, when dehiscent held at a similar height to or slightly below the stigma. Ovary 2.4–2.8 mm long, 0.5–0.6 mm diam., ± terete, green, glabrous; ovules 8–14; style 0.2–0.3 mm long, ± terete; stigma 0.2–0.3 mm diam. Siliques 6.0–15.0 × 1.0–1.2 mm, glabrous, style 0.3–0.8 mm long; valves green at maturity; straw-coloured when dehiscent, replum 0.4–0.6 mm wide. Seeds 0.6–0.7 mm long, 0.4–0.6 mm wide, 0.3–0.4 mm thick, orbicular to broadly oblong-orbicular, henna; wing absent.
