Silaus Bernhardi.

Herbs, perennial, glabrous. Stem erect, solid, striate, base clothed in fibrous remnant sheaths. Leaves long-petiolate, 3–4-pinnate; ultimate segments broadly lanceolate to linear, acute. Umbels compound, terminal and lateral; bracts absent or few, linear, deciduous; bracteoles numerous. Calyx teeth minute, conspicuous. Petals yellow, outer reddish-tinged, ovate, midvein elevated on both surfaces, apex narrowly inflexed. Stylopodium low-conic; styles short, reflexed. Fruit ovoid-oblong to subcylindrical, glabrous; mericarps subpentagonal in cross section; ribs 5, acute, narrowly winged; vittae small, numerous, obscure when mature. Seed face plane. Carpophore 2-cleft to base.

One to five species: Europe and the Mediterranean region; one species (introduced) in China.

The circumscription of Silaum is controversial, with some authors treating it as a unispecific genus (with only S. silaus) and others including up to five species.
