Moist, low grounds, Canada ! to Pennsylvania ! west to Ohio ! and West- 

 ern Missouri, Dr. Englemann. May-June. — Stem 4-6 feet high, l-2i 

 inclies in diameter at the base, fistulous, glaucous. Leaflets 2 or 3 inclies 

 long and 1-2 inches wide, paler and somewhat glaucous beneath ; the termi- 

 nal one united with the upper pair, or deeply 3-parted, sessile or abruptly and 

 slightly petiohdate. Petioles 1-2 inches in diameter. Umbels somewhat 

 globose after flowering, 6-8 inches or more in diameter ; the ra3^s and pe- 

 duncle minutely pubescent. Involucre wanting. Involucels of 8-12 short 

 subulate leaflets. Petals greenish-white, oval, with a subulate reflexed or 

 incurved point. Fruit nearly 3 lines long, frequently tricarpellary ; the dor- 

 sal ribs prominent but not winged. Vittaj about 24 ; 8 of which belong to 

 the commissure. — Common Angelica. 



/-- 4. A. hirsuta: stem striate, the summit, with the peduncle and rays of the 



' umbel, tomentose-pubescent ; leaves bipinnately divided ; the divisions usu- 

 ally quinate ; segments ovate-oblong, acute, or somewhat obtuse, equally 

 serrate, rather thick ; the upper pair connate, but not decurrent at the base ; 

 lower petioles elongated, dilated at the base ; umbels spreading ; fruit pu- 

 bescent. — Angelica" hirsuta, Muhl ! cat. ed. 2. 2^. 30. A. triquinata, NutL

Dry woods and thickets, New York! to South Carolina, not found west of 

 the Alleghany Mountains ? July-Aug. — Stem 2-5 feet high, simple, 

 straight, i-i inch in diameter at the base. Leaves distant : lower ones on 

 slender petioles 6-10 inches long ; the uppermost bhernately divided, with 

 shorter petioles, which are dilated the greater part of their length : segments 

 usually about li inch long, sliglitly and evenly but somewhat doubly ser- 

 rate ; the lower exterior one often 1-2-lobed at the base, so as to appear auri- 

 culate. Umbels on long peduncles, which are clothed with a dense white 

 pubescence ; rays about" 2 inches long. Involucels about as long as the um- 

 bellets, 6-10-leaved, often unilateral. Petals ovate, wuh an incurved point. 

 Fruit with 3 acute dorsal ribs. Vitta? usually 20 ; 8 of which belong to the 

 commissure. — Tins plant has much the appearance of the European An- 

 gelica sylvestris. 



-7-— 5. A. per egrina {^Vitt.\ mss.) : stem striate, pubescent at the summit; 

 leaves ternately divided, the divisions quinate; segments ovate, acute, in- 

 cisely serrate and somewhat lobed ; sheaths moderately dilated ; umbel 

 loose, with many slender rays ; involucre none ; involucels 9-14-leaved, 

 about as long as the umbellets ; fruit with the lateral ribs very thick and 

 scarcely winged. 



Grassy plains of Wappatoo Island, Oregon, Nuttall ! Sea Coast of Massa- 

 chusetts, Dr. Pickering! (fruit and flowers only.) "Differs from A. atro- 

 purpurea in its long many-leaved involucels, much larger flowers, and inthe 



> fruit, the dorsal ribs of which are much more prominent and the marginal 

 ones thick and obtuse, instead of thin and winged." Nutt.— Our Oregon spe- 

 cimen, received from Mr. Nuttall, resembles A. atro])urpurea in its thin 

 leaves with acute deeply serrated lobes, but differs in the characters pointed 

 out by Nuttall, and also in the more slender stem and smaller petioles. We 

 have not compared complete specimens from Maine and Oregon ; but the 

 fruit from the former locaUty seems to be quite diflTerent from that of A. atro- 

 purpurea. 



6. A. dentata (Chapman ! mss.) : stem slender, glabrous, finely striate ; 

 petioles long and slender ; lower leaves ternately divided ; the divisions ter-
