elongated linear entire bractlets equalling the flowers or longer; 
rays about one inch long; pedicels 2 to 3 lines long: fruit ovate, 
2 lines long, often. with a single prominent calyx-tooth: oil-tubes 
(in immature fruit) obscure: seed apparently not dorsally sulcate.

Alaska (early explorers, Rothroclc); Unalaska and Shumagis {Harring- 
ton in 1871-72); Behring Islands {Stejneger in 1882); Queen Charlotte’s 
Islands, B, 0 , July 15, 1878 (Dawson); also “Arctic shores and mountain 
slopes, wet borders of streams, Mitchell Creek, foot-hills of the Kocky 
Mts.,” July 11, 1883 (Dawson); said to have been collected in Labrador by 
Morrison (Macoun’s catalogue). 
7. S. Hookeri Watson in herb. Stout, 2 to 8 feet high, 
glabrous except the somewhat puberulent inflorescence: leaves 
large, with much dilated petioles, hipinnatifid, the narrowly ovate 
to linear-oblong acute segments an inch or less long, laciniately 
toothed or lobed to entire: umbel 10 to 25-rayed, with involucre 
of few deciduous linear-setaceous bracts, and involucels of nar- 
rowly linear m.ore or less elongated bractlets; rays about an inch 
long; pedicels 2 to 3 lines long: fruit oblong, glabrous, 2 to 234 
lines long, with prominent but scarcely winged dorsal and inter- 
mediate ribs, and rather broadly winged thickish lateral ribs; no 
strengthening ceils: seed but slightly dorsally sulcate. (Fig- 22.) 
— Conioselinum Bischeri of authors, in part. 
Alaska (Kellogg in 1867); Puget. Sound (Buckley); Ocean Bluffs, Long 
Beach, Ilwaco, Washington Territory, July and August, 1885 and 1886 
(Henderson 2160); Oi’egon (P. V. LeEoy’s distribution as Conioselinum 
Ftscheri). 
Probably this is the form commonly distributed as Conioselinum 
Fischeri. It bears a striking resemblance to C. Canadense. 
9. CONIOSELINUM Fisch. in Hoffm. Umbel. 185.— Tall 
glabrous perennial, with pinnately decompound leaves, few-leaved 
involucre or none, involucels of elongated linear-setaceous bractlets, 
and white flowers. 
The foreign species of Conioselinum have been merged with Ligusticum 
and our own species put into Selinum by Bentharn & Hooker. J’heir 
decision in reference to our species was based upon immature fruit, while 
study of a quantity of fine fruiting material has led us to restore it to generic 
rank. 5 It differs so decidedly from our definition of Ligusticum that it 
is only necessary to call attention to the characters which separate it from
