形態特徵

A perennial, glabrous herb, 10–80 cm high, with fibrous roots; stems branching, striate, glabrous.
Leaves petiolate, 3–10 cm long, oblong to ovate, pinnate to tripinnate; ultimate segments ovate, narrow-ovate or linnear, the margins serrate or entire; petioles 2–10 cm long, sheathing.
Umbels compound; involucre lacking, or of a few linear bracts; rays 5–15, 0.5–3 cm long; involucels several, linear. Flowers white; style long, persistent.
Fruit glabrous, oblong, about 2.5 mm long, 1.5–2 mm broad, the commissure broad, the ribs low, very corky. Vittae 1 in the interval, 2 on the commissure.
This is a very variable species. I have made extensive collections of this species and found many specimens with two different kinds of leaves, one ovate and with serrate ultimate segments and the other linear and entire.
