Plants strongly rhizomatous. Leaves 1-pinnate, more or less membranous, (2—) 3—8(—13) cm long. Leaflets (1—) 3—5(—7) pairs, usually flabellate and simple (or rarely palmately incised), regularly serrate, distinctly glaucous on under surface, glaucous or not on upper surface, 3-10 mm long. Petiolules absent. Inflorescence 3—15(—25) cm long; umbels 1(-2) per inflorescence; umbellets (1—)2—3(—4) per umbel; flowers 1-9 per umbellet. Bracts fused; bracteoles 1-5, usually free, sometimes somewhat fused. Mericarps 3-4 mm long; lateral ridges not winged (or rarely very slightly winged).

Plants not or slightly rhizomatous. Leaves 1- to 2-pinnate, more or less subfleshy, (2-)4-12(-20) cm long. Leaflets (2-) 3-8 (-10) pairs (very rarely reduced to terminal leaflet only), shape and form very variable from linear, ovate, spathulate to suborbicular; simple, deeply pinnately incised (sometimes palmately) or pinnate; serrations usually irregular; usually distinctly glaucous on both surfaces; 4-30 mm long. Petiolules present in proximal leaflets, or absent. Inflorescence 4—15(—25) cm long; umbels 1—3(—4) per inflorescence; umbellets (1-)2-5(-6) per umbel; flowers 2-16 per umbellet. Bracts fused; bracteoles 3-5, usually somewhat fused, sometimes free. Mericarps 3-6 mm long; lateral ridges not winged (or rarely very slightly winged).
