Prostrate, decumbent or erect perennial herbs up to 30 cm high. Sterns and branches puberulous with hyaline, sometimes clavate, hairs. Basal leaves crowded in a rosette, frequently dying off before flowering, pecti-nately 7-15-lobed, the lobes semi-lunate, entire or shallowly toothed, puberulous on the upper surface; gradually smaller and less lobed to dentate. Stem leaves 0-5-7-5 cm long, 1-5 mm broad, lanceolate or oblanceo-late, entire, acute, cuneate, with a few hairs on the margin in the lower half. Racemes many-flowered, at first dense and contracted, in fruit up to 10 cm long (under poor condiÂtions much reduced and barely 1 cm long); rhachis puberulous. Sepals 0 • 7-0 • 8 mm long, greenish white or tinged with purple. Petals scarcely longer than the sepals, white. StaÂmens 2; filaments subulate. Siliculae on erect pedicels 1-3 mm long, of two almost globose halves, each (0-5-) 0-8-1 mm in diameter, keeled, warted or pitted (rarely almost smooth or papillate); style exserted from the sinus or not.
