Small slender ± pilose herb with mainly radical lvs; stock uni-multicipital; main root deeply descending. Lvs on slender petioles up to 3 cm. long, sheathing at base. Lamina 1-5-(10) cm. long, narrow-oblong in outline; pinnate (to pinnatisect or pinnatifid in upper portion); pinnae us. deeply sharply serrate on anterior margin, teeth sts piliferous. Stems us. several, branched, prostrate, up to 30 cm. long, us. less, very slender, ± flexuous, bearing a few narrow-spathulate to narrow-obovate to linear entire or serrate lvs. Racemes slender, terminal, ± 3 cm. long; fls minute, us. ∞.Sepals 4, petals us. 0, stamens 4. Pods orbicular on very slender peduncles, narrowly winged. towards apex, minutely notched; style hardly > notch. Seeds oblong in outline, finely muriculate.

Racemes 5-10 cm long at fruiting; rachis and pedicels glabrous or sparsely hairy; pedicels distant, spreading, 2-4 mm long at fruiting. Sepals sparsely hairy or rarely glabrous, 0.5-1 × 0.3-0.5 mm. Petals usually 0, or white, < sepals. Stamens usually 4.
