Calyx-teeth obsolete. Petals obcordatc or oI)f)v:ite, with ;ui inllexcd jio'mi. 

 Styles slender, at length reflcxed. Fruit convex, or compressed on the back. 

 Carpels witli 5 winfred ribs ; the lateral ones twice as broad as tlje olliers and 

 marginal. Lateral intervals with3vhUE: dorsal ones often with 2 villa-. 

 Commissure wilh 4-8 unequal vitta;. Carpophore 2-parted. Seed flat on 

 the face. Biennial glabrous herbs, with branching and fislidous stems. 

 Leaves with very large inflated petioles, teriiately divided ; the divisions bi- 

 pinnately parted, with oblong-linoar lobes. Involucre none, or few-leaved. 

 Involucels of 5-7 linear-subulate leaflets. Flowers white.

Labrador, Arctic America, Kotzebue's Sound, and Straits of Da Fuca, 

 Hooker. Sitcha, Bonsard. — We have seen no American specimens of this 

 plant. C. Ingricum, Fisch. viss. (which is doubtless tlie same species, and 

 of which we have an authentic specimen) is a stout plant wilh the habit of 

 Conium maculatum; the rays of the umbel verv' numerous; the fruit de- 

 cidedly longer and narrower than in C. Canadense ; with smaller and flatter 

 vittffi ; of wiiich there are 2-3 in each inter^'al, and 4-G in the conmiissure. 



-l- 2. C. ? Canadense : fruit broadly oval ; dorsal ridges narrowly winged ; 

 vittae 2-3 in the lateral intervals, solitary in the dorsal ones. — Sclinum Cana-

Shady wet places^ Oneida County, New York, Dr. Kneiskern ! Castlcton, 

 Vermont, Dr. Tally! Southern Shore of Lake Superior, Dr. Pitcher! 

 Mouth of the River St. Lawrence, Michaux ! Aug.-Se])t. — Stem 3-5 feet 

 high, terete, finely striate. Leaves with inflated sheathing petioles; the 

 divisions pinnately compound; segments pinnatifid ; the lobes linear-oblong. 

 Umbel of 10-lG rather slender spreading rays, which are about 2i inches 

 long. Involucre none, or of 2-3 subulate leaflets. Involucels 5-()-leaved, 

 nearly as long as the umbellets. Styles slender, diverging. Calyx-teeth 

 nearly obsolete. Petals much spreading, emarginate and somewhat ungui- 

 culate; the point short and inflexed. Fruit about 2 lines long, much com- 

 pressed on the back ; the lateral ribs dilated into a conspicuous wing. \'itta' 

 of the lateral intervals sometimes solitary, but usually 2 and rarely 3. often 

 anastamosing; those of the commissure at least 4, but often several other shorter 

 ones, and occasionally another at the margin of the wing. — We refer this 

 plant to Conioselinum with some doubt ; as the dorsal ribs are but slightly 

 winged, and the vitta? are less numerous than in the species on which the 

 genus was founded.
