 root cylindric, thick and fleshy; leaves all basal, mostly biternate or ternate; 

 and then quinate; leaflets ovate to narrowly lanceolate, entire or with a few 

 teeth at the apex, 3-5 cm. long, thickish; peduncles stout, 10-30 cm. high; 

 rays unequal, 4-20 cm. long; flowers yellow; fruit smooth, oblong, 9-14 mm. 

 long. 



In sandy or gravelly soil, Vancouver Island, British Columbia, to Cali- 

 fornia. 



Cogswellia utriculata (Nutt.) Jones. Glabrous or merely puberulent; 

 leaves mostly basal, 1 or 2 cauline, ternately or pinnately decompound, the 

 ultimate segments narrowly linear, 6-12 mm. long; petioles dilated at base; 

 peduncles or stems 20-30 cm. high; rays unequal, 2-5 cm. long; flowers yellow; 

 fruit elliptical, glabrous, 2-7 mm. long. 



Prairies, Vancouver Island, British Columbia, to California. Root tuber- 

 ous, said to have been used by the Indians for food. First collected by Nuttall 

 near the mouth of the Willamette River. 



Cogswellia triternata (Pursh) Jones. Peduncles 30-70 cm. tall; leaves 

 bipinnate or triternate, puberulent; leaflets linear-lanceolate, 5-15 cm. long; 

 umbel unequally 5-18-rayed, the rays 1-5 cm. long; fruit oblong, glabrous, 

 6-12 mm. long; oil-tubes large, solitary between the ribs; two on the inner side. 



Prairies from near the head of Puget Sound, southward. 



Cogswellia hallii (Wats.) Jones. Glabrous; leaves mostly basal, a few 

 cauline, pinnate, oblong in outline, the segments ovate, deeply toothed or 

 pinnatifid, about 1 cm. long; umbel 3-6-rayed; flowers yellow; fruit elliptical, 

 glabrous, 6 mm", long, with 3 oil-tubes in the intervals between the ribs and 4 on 

 the inner side. 



Mount Hood, Oregon, Howell; Mount Saint Helens, Washington, Mrs. 

 Biggs, a doubtful specimen; not otherwise known. 



Cogswellia martindalei (Coult.& Rose) Jones. Glabrous, somewhat glau- 

 cous, leaves rather thick, bipinnate, the ultimate segments ovate, toothed or 

 pinnatifid, 10-12 mm. long; stems bearing 1 or 2 leaves, 15-40 cm. high; fruit 

 glabrous, 8-16 mm. long, the wings as broad as or broader than the body; oil- 

 tubes solitary in the intervals between the ribs, two on the inner side. 



Bluffs of the Columbia River at Bridal Veil, Oregon, and southward. 



Cogswellia angustata Coult. & Rose. Very similar to C. hallii, but fruit 

 with one oil-tube in each interval and two on the inner side. 



Common in rocky places in the mountains at about 1500-2000 m. altitude. 

 Probably only a form of C. hallii. 



345. ANGELICA. 



Stout perennial herbs; leaves ternate, then pinnate, rarely 

 simply pinnately compound; involucre scanty or none; involucels 

 of small bractlets or none; flowers in large terminal umbels; 

 calyx-teeth mostly obsolete; stylopodium conical; fruit flattened 

 dorsally, ovate or oblong, glabrous or pubescent; calyx-tube 

 prominent, crenulate; carpels with strong ribs, the lateral ribs 

 usually broadly winged, distinct from those of the other carpel, 

 forming a double-winged margin to the fruit; oil-tubes 1 -several 

 in the intervals, or indefinite, 2-10 on the commissural side; 

 seed face plane or somewhat concave. 



Leaves densely tomentose beneath. A. hendersoni. 



Leaves glabrous or nearly so.
