DMBELLIPEEJE. (pAESLET FAMILY.) 193 



12. ARCHAWGi^LICA, Hoffm. Arohangelica. 



Calyx-teeth short. Seed becoming loose in the pericarp, coated with numer- 

 ons oil-tubes which adhere to its surface. Otherwise as in Angelica, from which 

 the species have been separated, with hardly sufficient reason. 



1. A. hirstlta, Torr. & Gr. Woolly or downy at the top (2° -5° high), 

 rather slender; leaves twice pinnately or ternately divided; leaflets thickish, 

 ovate-oblong, often blunt, serrate ; involucels as long as the nmbellets ; pedun- 

 cles andyrMi( downy, broadly winged. (Angelica triquinkta, Nutt.) — Dry open 

 woods, New York to Michigan, and southward. July. — Tlowers white. 



2. A. atropurptirea, Hoffm. (Gkeat Angelica.) Smooth; stem dark 

 Tpnvfle, very stout (4° -6° high), hollow; leaves 2 - 3-ternately compound; the 

 leaflets pinnate, 5-7, sharply cut serrate, acute, pale beneath; petioles much 

 inflated ; involucels very short ; fruit smooth, winged. (Angflica triquinkta, 

 Michx.) — Low river-banks, New England to Penn., Wisconsin, and northward. 

 June. — riowers greenish-white. Plant strong-scented. 



3. A. Gm^lini, DC. Stem a little downy at the summit (l°-3°high); 

 leaves 2 - 3-ternately divided ; the leaflets ovate, acute, cut-serrate, glabrous ; in- 

 volucels about as long as the umbellets ; fruit oblong with 5 thick and corky wing- 

 lilce ribs to each carpel, the marginal ones little broader than the others. (A. pere- 

 gri'na, Nutt., & ed. 2.) — Kocky coast of Massachusetts Bay and northward. 

 July. — Flowers greenish-white. Plant little aromatic. Fruit so thick and so 

 equally ribbed, rather than winged, that it might be taken for a Ligusticum. 



13. CONIOSELtNUM, Fischer. Hemlock-Parslet. 



Calyx-teeth obsolete. Fruit oval : the carpels convex-flattish and narrowly 

 3-winged on the back, and each more broadly winged at the margins : oil-tubes 

 in the substance of the pericarp, 1 - 3 in each of the intervals, and several on 

 the inner face. — Smooth perennials, with finely 2 - 3-pihnately compound thin 

 leaves, inflated petioles, and white flowers. Involucre scarcely any : leaflets of 

 the involucels awl-shaped. (Name compounded of Conium, the Plemlock, and 

 Selinum, Milk-Parsley, from its resemblance to these two genera.) 



1. C. Canad6nse, Torr. & Gr. Leaflets pinnatifld ; fruit longer than the 

 pedicels. — Swamps, Vermont to Wisconsin northward, and southward through 

 the AUeghanies. Aug. — Herbage resembling the Poison Hemlock. 



14. JETHUSA, L. Fool's Parsley. 



Caly.x-teeth obsolete. Fruit ovate-globose ; the carpels each with 5 thick 

 sharply-keeled ridges : intervals with single oil-tubes. — Annual, poisonous 

 herbs, with 2 - 3-ternately compound and many-cleft leaves, the divisions pin- 

 nate, and white flowers. (Name from a'i6a>, to bum, from the acrid taste.) 



1. .ffi. CynXpixjm, L. Divisions of the leaves wedge-lanceolate ; involucre 

 none : involucels 3-leaved, long and narrow. — About cultivated grounds, New 

 England to Penn. July. — A fetid, poisonous herb, with much the aspect of 

 Poison Hemlock, but with dark-green fohage, long hanging involucels, and 

 unspotted stem. (Adv. from Eu.)
