Calyx-teeth obsolete. Petals lanceolate, entire, acuminate ; the point 

 straight or incurved. Fruit dorsally compressed. Carpels with 3 elevated 

 filiform dorsal ribs : lateral ribs forming marginal wings. Intervals with 

 single vittce. Commissure with 2-4 vitt<e. Carpophore 2-parted. Seed 

 semiterete. — Perennial or biennial herbs. Petiole 3-parted; the divisions 

 bipinnately divided. Umbels terminal. Involucre none, or few-leaved. 

 Involucels many-leaved. 



1. A. arguta (Nutt. ! mss.) ; " stem striate and glabrous ; divisions of the 

 leaves pinnately, and some of them bipinnately, divided ; the segments 

 ovate, glabrous, rather acute, serrate, the terminal one 3-cleft or deeply 

 3-parted ; involucre and involucels none ; fruit (large) oblong-elliptical." 



Wappatoo Island, and near Fort Vancouver, Oregon, Nuttall! — Segments 

 of the leaves 1-li inch long, sessile, or slightly petiolulate. " Raj^s of the 

 umbel 50-60. Petals short, elliptical, with a conspicuous inflexed point." 

 Nutt. Fruit greenish- white, 3 lines long ; the dorsal ribs slightly elevated, 

 not winged ; lateral ones with wings as broad as the seed. Intervals with 

 single conspicuotis vittre. Commissure with 2 distant vittre. — Nearly allied 

 to A. sylvestris, but differs in wanting the involucre and involucels. 



2. A. genufiexa (Nutt. ! mss.) : " stem striate and glabrous ; divisions of the 

 leaves pinnately or bipinnately divided ; the segments ovate-lanceolate, 

 acuminate, unequally and coarsely serrate, sessile ; involucre none ; invo- 

 lucels about 7-leaved ; fruit nearly orbicular." 



With the preceding ; also in mountain rivulets east of Wallawallah, 

 Nuttall ! — Stem apparently 4-5 feet high. Sheaths of the leaves somewhat 

 dilated. " Divisions of the leaves, particularly of the lower ones, often angu- 

 larly deflexed." Leaflets 2-4 inches long, membranaceous, almost incisely 

 serrate. Umbel of 30-40 elongated slender rays ; the raN's and peduncle 

 pubescent. Petals obovate, with an inflexed point. Fruit about 2 lines 

 long ; dorsal ribs slightly elevated ; the lateral ones dilated into . a broad 

 wing. Commissure with 2 distant vittEe. — We have a specimen (without 

 fruit) of what appears to be the same plant, collected in Oregon by Dr. 

 Scouler.

Canada, Cornuti. {v. s^i. in herh. Vaillant !) — " Wholly glabrous. Root 

 an inch thick, with the odor of Parsley, acrid, perishing the second or third 

 year. Stem 1-2 feet high, about as thick as one's finger, erect or flexuous, 

 branched, fistulous, striated above. Radical leaves 3-, the cauline 2-pinnate; 

 leaflets lanceolate or ovate, rather acute, dark green and shining on the upper 

 surface, very smooth underneath ; the terminal ones confluent. Umbels 

 and umbellets convex, dense; the rays striated. Involucre of 5 narrow 

 lanceolate leaflets; those of the involucel equal in number to the rays,
