Sinocarum dolichopodum (Diels) H. Wolff ex Pu Fating

This species has reputed medicinal value. The long rhizome, leaf morphology, and divided bracteoles are rather uncharacteristic of Sinocarum, and this species may be better placed elsewhere.

Basal petioles 3–6 cm, sheaths ovate, purplish; blade triangular in outline, 3–6 × 2–3 cm, 2–3-pinnate; pinnae 3–5 pairs, basal pinnae petiolate; ultimate segments ovate, 10–15 × 5–8 mm, margins 3-lobed or pinnatifid. Umbels 4–7 cm across, sometimes subtended by a reduced, 3-lobed leaf; bracts absent; rays 4–6, 4–5 cm, stout; bracteoles 2–6, linear-oblanceolate or obovate in outline, 4–7 mm, apex usually 2–3-lobed, or pinnatifid, rarely entire; umbellules 10–18 mm across, 10–15-flowered; pedicels 4–8 mm.
