Characteristics

Perennial. Main stems erect, 20-45 cm tall; branches lf-opposed, spreading, ridged, ± densely covered with fine, short, backward-pointed hairs. Basal lvs withering at fruiting; early lvs glabrous; later lvs sparsely bristly above and beneath; margins with triangular or 2-lobed cartilaginous denticles; lamina narrow-oblancolate, pinnate, 6-12-(20) × 1.5-2.5-(4) cm; pinnae in (3)-5-8 pairs, toothed, especially on distal margin. Stem lvs becoming simple, bristly; margins with small triangular or 2-lobed cartilaginous denticles; middle lvs narrow-oblanceolate, toothed, cuneate at base, 1.5-3 × 0.5-1.5 cm; upper lvs narrow-oblong, toothed or 3-fid at apex, 5-15 × 2-4 mm, abruptly narrowed or sub-auriculate at very shortly stalked base. Racemes (3)-5-10 cm long; rachis and pedicel hairs as on stems; pedicels erecto-patent to patent, 3-4 mm long at fruiting. Sepals glabrous or sparsely hairy, often purplish with scarious margin, 0.7-1 × c. 0.5 mm. Petals white, much < sepals. Stamens 2. Silicles ovate, 2.7-3 × 2-2.3 mm; stigma almost sessile in shallow notch; valves usually purple, glabrous or sparsely hairy. Seed narrow-ovoid, brown, not winged, c. 1.5 mm long.
More
Perennial herb to 40 cm high, erect to spreading; stems usually scabrous, the hairs often bilobed or deflexed. Basal leaves pinnate, the lobes dentate, terminal lobe the largest; hairs sometimes larger and coarser than on stems. Cauline leaves distant, spathulate to narrowly cuneate, serrate near apex; base variable from attenuate to auriculate; marginal hairs arising above a warty projection and often bilobed. Inflorescence a raceme. Sepals 0.5–0.75 mm long. Petals very reduced, linear. Stamens 2, median. Stigma subsessile to sessile. Silicula dehiscent, elliptic to ovate, 2.5–3 mm long, 1.75–3 mm wide, usually glabrous; wing slight in upper half, forming a small apical notch; pedicels 2.5–3 mm long, puberulous, spreading. Seeds c. 1.5 mm long; radicle incumbent.
