Stems and main branches with greyish bark, smooth, slightly fissured in thicker and older parts, with numerous scars of fallen leaves. Branchlets greyish or greenish-white, with few rigid hairs. Leaves (up to 5 \u00d7 3 cm) alternate, obovate-oblong \u2014sometimes spatulate\u2014, obtuse, entire or with some very pronounced lobes, slightly fleshy, green on both sides, glabrous or with few scattered hairs. Flowers in small short terminal racemes, of 4-6 flowers. Calyx with 4 sepals, linear-oblong, \u00b1 acute, glabrous, greenish-yellowish, 10 mm long. Corolla with 4 petals, obovate and longly unguiculate, 12-15 mm long, very intense yellow. Fruit a subsessile silicle 17-20 \u00d7 2-3 mm, with 2 parts or segments: lower part fertile, ellipsoid, dehiscent in 2 to short and convex valves, with some rigid hairs and visible veins; upper part (rostrum) sterile, linear-lanceolate, trinervate, glabrous, 3 times longer than the lower part.
