Basionym: Alyssum petraeum Arduino Animadv. Bot. Spec. Alt., 30. 1764
Treatment appears in FNA Volume 7. Treatment on page 251. Mentioned on page 252.

Plants slightly woody at base; finely stellate-pubescent. Stems: usually several, 1.5–6 dm. Basal leaves: petiole 0.3–2.5 (–3.5) cm; blade obovate-oblong, 2.5–8 cm × 3–10 mm, base cuneate to attenuate, margins entire, sinuate, or pinnatifid, apex acute or obtuse, surfaces densely pubescent. Cauline leaves: blade oblanceolate to linear. Racemes considerably elongated in fruit. Fruiting pedicels 3–8 mm. Flowers: sepals yellowish, 1.5–2 × 0.5–1 mm, scarious at margins, finely pubescent; petals 3–4.5 × 1.2–2 mm, attenuate to clawlike base; filaments with basal wing or appendage to 0.5 mm, 1.2–2 mm; anthers 0.3–0.5 mm. Fruits divaricate-ascending, ellipsoid to obovoid, inflated at middle, slightly flattened at margin, 3–6 × 2–4 mm; style slender. Seeds winged throughout, 1.5–1.8 mm diam.; wing 0.1–0.3 mm wide. 2n = 16.
