Annual, biennial or perennial herbs Leaves 2–4-pinnate, with numerous toothed leaflets Umbels few–numerous, compound, usually pedunculate; involucre absent or of 1–2 bracts; involucel conspicuous, of several frequently reflexed bracteoles Flowers usually polygamous, with some inner flowers of each partial umbel ♂, more rarely some partial umbels entirely ♂ Calyx-teeth minute or obsolete Petals white or pinkish, sometimes radiant, the non-radiant ± emarginate above, without or with a minute incurved lobule Endosperm horseshoe-shaped, deeply sulcate on the commissural face. Fruit glabrous or hispid with antrorse, tuberculate-based bristles, elliptic-oblong to ovate, narrowed upwards, with a short and obscure or longer beak, laterally compressed, mericarps rounded into the narrow commisure; primary ribs very slender, the mericarps almost rounded to slightly 3-angled dorsally; vittae very slender and inconspicuous in the valleculae and sometimes apparently absent, commissure with a single vitta on each side of the central groove; stylopodia conical, styles short; carpophore entire or shortly bifid Leaves 2–4-pinnate, with numerous toothed leaflets Umbels few–numerous, compound, usually pedunculate; involucre absent or of 1–2 bracts; involucel conspicuous, of several frequently reflexed bracteoles Flowers usually polygamous, with some inner flowers of each partial umbel ♂, more rarely some partial umbels entirely ♂ Calyx-teeth minute or obsolete Petals white or pinkish, sometimes radiant, the non-radiant ± emarginate above, without or with a minute incurved lobule Endosperm horseshoe-shaped, deeply sulcate on the commissural face.
