(The ancient Greek name.) C. NODÒSA, Hudson. Decumbent, branching only at base, stems 1--2° long, retrorsely hispid; umbels naked, opposite the leaves and nearly sessile, of 2 or 3 very short rays.--Md., Iowa, and southward. (Nat. from Eu.) C. ANTHRÍSCUS, Hudson, has 1--2-pinnate leaves with broad leaflets, and more regularly compounded umbels.--Ohio, etc. (Nat. from Eu.) 3. ANGÉLICA, L. Calyx-teeth obsolete. Fruit strongly flattened dorsally; primary ribs very prominent, the laterals extended into broad distinct wings, forming a double-winged margin to the fruit; oil-tubes one to several in the intervals or indefinite, 2 to 10 on the commissure.--Stout perennials, with ternately or pinnately compound leaves, large terminal umbels, scanty or no involucres, small many-leaved involucels, and white or greenish flowers. (Named _angelic_ from its cordial and medicinal properties.) [*] _Seed adherent to the pericarp; oil-tubes one to several in the intervals; uppermost leaves mostly reduced to large inflated petioles._ 1. A. Curtísii, Buckley. Glabrous; leaves twice ternate or the divisions quinate; _leaflets thin_, ovate-lanceolate (_1--3´ broad), sharply and irregularly toothed; fruit glabrous_, 1½--3´´ broad; oil-tubes mostly one in the intervals (sometimes 2 or 3).--Along the Alleghanies from Penn. to N. C. Aug. 2. A. hirsùta, Muhl. _Pubescent above_; leaves twice pinnately or ternately divided; _leaflets thickish_, lanceolate to oblong (_5--10´´ broad), serrate; fruit pubescent_, 2´´ broad; oil-tubes 3--6 in the intervals. (Archangelica hirsuta, _Torr. & Gray_.)--Dry ground, Conn. to Minn., Tenn., and Fla. July. [*][*] _Seed loose; oil-tubes indefinite (25--30); upper petioles not so prominent._ 3. A. atropurpùrea, L. Very stout, glabrous throughout, with dark purple stem; leaves 2--3-ternately divided, the pinnate segments of 5--7 lanceolate to ovate leaflets (1--1½´ broad), sharply mucronate-serrate.

Fruit oval, flattened dorsally, glabrous, the dorsal ribs very prominent, the lateral ones extended into broad wings; oil-tubes 1--4 in the intervals, 4--8 on the commissure; seed slightly concave on the inner face.--Tall slender glabrous perennial, with finely 2--3-pinnately compound leaves, few-leaved involucre or none, involucels of elongated linear-setaceous bractlets, and white flowers. (Compounded of _Conium_ and _Selinum_, from its resemblance to these genera.)
