C. Petroselìnum, Benth., the common Parsley, from Europe, with 3-pinnate leaves, ovate 3-cleft leaflets, and greenish yellow flowers, is occasionally found as an escape from cultivation. (Petroselinum sativum, Hoffm.)

Calyx-teeth prominent. Fruit oblong to nearly orbicular, glabrous, with strong flattish corky ribs (the lateral largest); oil-tubes conspicuous, solitary; stylopodium depressed; seed nearly terete.—Smooth marsh perennials, very poisonous, with pinnately compound leaves and serrate leaflets, involucre usually none, involucels of several slender bractlets, and white flowers.

1. C. maculàta, L. (Spotted Cowbane. Musquash Root. Beaver-Poison.) Stem stout, 2–6° high, streaked with purple; leaves 2–3-pinnate, the lower on long petioles; leaflets lanceolate to oblong-lanceolate (1–5´ long), acuminate, coarsely serrate, the veins passing to the notches; pedicels in the umbellets numerous, very unequal; fruit broadly ovate to oval, 1–1½´´ long.—Throughout the U. S. Aug.
2. C. bulbífera, L. Rather slender, 1–3° high; leaves 2–3-pinnate (sometimes appearing ternate); leaflets linear, sparsely toothed (1–2´ long); upper axils bearing clustered bulblets; fruit (rare) scarcely 1´´ long.—Common in swamps, N. Scotia to Del., west to Minn. and Iowa.

Fruit ovate, glabrous, with equal filiform ribs, and no oil-tubes; stylopodium conical and prominent; seed nearly terete.—A coarse glabrous perennial, with creeping rootstock, biternate leaves, sharply toothed ovate leaflets, and rather large naked umbels of white flowers. (Name from αἴξ, goat, and πόδιον, a little foot, probably from the shape of the leaflets.)
