Robust to slender, erect to creeping, annual, biennial or perennial herbs. Leaves variously pinnate or ternate. Umbels compound, sessile or pedunculate, usually leaf-opposed; bracts 0–few; bracteoles few–numerous. Flowers hermaphrodite. Calyx-teeth obsolete or very small. Petals small, white or greenish, sometimes with a short incurved lobule but rarely emarginate above. Fruit glabrous, almost round to elliptic-oblong, laterally compressed; primary ribs conspicuous, slender to very thick; valleculae 1-vittate, the narrow commissure 2-vittate; stylopodia low, very shortly conical or flat, styles slender to obsolete; carpophore entire to shortly bifid at the apex. Endosperm roundish to quite sharply pentagonal in section.
Annual, biennial, or perennial glabrous herbs from taproots or creeping root-stocks; stems erect to prostrate, usually branched, the leaves petiolate, pinnate to ternate-pinnately decompound, the petiole sheathing; inflorescence of compound (or frequently some simple) umbels with or without an involucre and involucel; flowers white or greenish, the petals with an inflexed apex, the calyx minute or obsolete; stylopodium short-conical to depressed, the styles short, the carpophore entire, bifid, or 2-cleft; fruit compressed laterally and constricted at the com-missure, the ribs filiform, prominent, obtuse, the vittae solitary in the intervals, 2 on the commissure; seed subterete, its face flat.
Glabrous annual, biennial or perennial herbs, usually with taproots, sometimes rooting at nodes. Lvs 1-3-pinnate; segments broad or narrow. Umbels usually compound, often ± sessile and lf-opposed, sometimes shortly pedunculate; bracts few and simple or 0; bracteoles several or 0. Petals white or greenish, regular, with entire, obtuse to acute, usually inflexed apex; calyx teeth minute or 0. Fr. ovoid-oblong to subglobose, slightly flattened laterally, not beaked, spinless; commissure narrow; ribs 5 per mericarp, equal, stout or slender; vittae solitary in furrows.
Annual, biennial or perennial herbs, erect or creeping, usually taprooted, glabrous. Leaves alternate, pinnate or stem leaves sometimes ternate; leaf segments broad to linear. Inflorescence terminal or leaf-opposed, pedunculate to ± sessile, usually compound; bracts and bracteoles small or usually absent. Sepals minute or absent. Petals ovate to suborbicular, inflexed at apex, white or greenish white. Fruit ellipsoidal, ovoid or subglobose, slightly flattened laterally; mericarps 5-ribbed; oil canals sometimes present.
Fr oval to rotund, flattened laterally, somewhat constricted along the commissure; ribs 5 per mericarp, elevated; oil-tubes solitary in the intervals, 2 on the commissure; carpophore entire or not cleft beyond the middle; umbels terminal and lateral, compound, the lateral sometimes sessile; umbellets small; sep minute or none; pet white or greenish-white; stylopodium short-conic to depressed; lvs once pinnate to decompound. 10, widespread.
