Glabrate perennial herb, with ∞ flexuous decumbent branches up to 2 dm. long, and somewhat fleshy lvs. Lower lvs 5 cm. long or more, on long petioles, linear-oblong in outline, pinnatifid to pinnate; upper c. 1·5 to 2.5 cm. long, spathulate, narrowed to long or short petiole, irregularly crenate-lobed to almost entire. Racemes up to 5 cm. long, lateral and lf-opposed and terminal with minute fls on spreading pedicels c. 4 mm. long. Sepals ovate, ± 0·5 mm. long; petals shorter, linear, obtuse; stamens 2. Silicles ovate to oval in outline, c. 4 mm. long, c. 2.5 mm. wide, notched, narrowly winged above; style not exceeding notch. Seeds ovoid, compressed, reddish brown, 1-2 mm. long.

Perennial herb. Stems prostrate to decumbent, 10- 25(-40) cm long, finely puberulent with short papillate or tapered hairs. Leaves fleshy, dull green. Basal and lower cauline leaves withering at fruiting, glabrous above, with papillae or denticles along midrib beneath and margins, pinnatifid, obovate to oblanceolate, 5-7 × 1.5-2.5 cm; pinnae in 1-3 pairs, bluntly toothed or crenate at apex and distal margins. Cauline leaves obovate, oblanceolate, or spathulate, bluntly toothed to crenate distally, cuneate at base, 10-25(-30) × 5-10 mm, with triangular denticles dense on margins and sparse to dense beneath, glabrous above. Racemes 15-40(-50) mm long, terminal and leaf-opposed; rachis and pedicels puberulent with short tapering hairs, or glabrous; pedicels erecto-patent, 3-4 mm long at fruiting. Flowers c. 2 mm diameter. Sepals glabrous or sparsely hairy, green with scarious margins, c. 1 × 1 mm. Petals white, about equalling sepals, erect, not clawed, narrow-obovate to narrow-oblong, entire and rounded at apex. Stamens 2. Nectaries 4, very small; nectar slight. Siliques broadly elliptic to broadly ovate, (3.2-)3.5-3.8 × 2.2-2.5(-2.8) mm; style 0.1- 0.2 mm long, free from the narrow rounded wing, shorter than the notch; stigma 0.3 mm diam.; valves glabrous. Seed broadly obovoid, brown, not winged, 1.6-2 mm, mucilaginous when wet. FL Oct-Jan, FR Dec-Apr.

Perennial. Stems ascending to erect, 15-30 cm tall, glabrous or with papillose hairs especially above. Lvs ± fleshy. Basal lvs withering at fruiting, glabrous, pinnatifid to pinnate, narrow-obovate to narrow-oblong, 5-10-(15) × 1-2-(3) cm; pinnae in 2-5 pairs, coarsely to bluntly toothed, especially distally. Stem lvs narrow-obovate to spathulate, toothed or crenate at apex, cuneate to rather abruptly narrowed at base, 10-30 × 5-10 mm, glabrous or with sparse surface hairs and rounded, almost papillate, cartilaginous marginal denticles. Racemes 10-30-(40) mm long; rachis and pedicels glabrous or sparsely hairy; pedicels erecto-patent, 3-5 mm long at fruiting. Sepals glabrous or sparsely hairy, green with scarious margins, c. 1 × 0.5 mm. Petals white, < sepals. Stamens 2, rarely 4. Silicles ovate to suborbicular, 3-4 × 2.5-3 mm, crowded; style 0.1-0.2 mm long, free from the narrow wing, c. = the notch; valves glabrous. Seed narrow-ovoid, brown, not winged, c. 1.5 mm long.
