50. CARUM Linn. Gen. n. 365. — Smooth erect slender 
herbs, with tuberous or fusiform fascicled roots, pinnate leaves 
with few linear leaflets, involucre and involucels of few to many 
bracts, and white flowers. 
Our American species foi’m the section Edosmia Benth. & Hook, (ex- 
cepting C. Hoivellii). The roots are used as an articie of food among the 
Indians. 
1. C. Gairdneri Benth. & Hook. Gen. Plant, i. 891. Stem 
1 to 4 feet higfh, from fascicled tuberous or fusiform roots: leaves 
few, usually simply pinnate, with 3 to 7 linear (sometimes almost 
filiform) leaflets 2 to 6 inches long (the lower rarely pinnate); 
upper leaves usually simple: umbels 6 to 15-rayed, with involucre 
of several bracts or none, and involucels of linear acuminate bract- 
lets; rays about 1^ inches long: fruit ovate, small, ^ to 1 line 
long, with long styles: seed terete. (Fig. 150 .) — Edcsmia Gaird- 
neri Torr. & Gray, FI. i. 612. 
From S. California to British Columbia, and eastward to Utah, Wyom- 
ing and Montana. Very common on Vancouver Island (MacGun), FI. June 
and July. 
Var. latifolium Gray, Proc. Am. Acad. vii. 344. Leaflets 
broader, linear-lanceolate, about ^ inch broad. 
California, Ebbett's Pass (Brewer), Yosemite (Bolander); Nevada, near 
.Carson City (C. L. Anderson). 
2. C. Oreganum Watson, Proc. Am. Acad. xx. 368. 
Closely resembling the preceding, but with lower leaves more 
divided, with shorter linear lobes: fruit oblong, larger, Ij^ to 2 
lines long, with long styles: seed flattened dorsally, sulcate beneath 
the oil-tubes, and slightly concave on the face, with central longi- 
tudinal ridge. (Fig. 151 .) — Edosmia Oreganum Nutt, in herb. 
California, Siskiyou Co. (Greene); Nevada, East Humboldt Mts. (Wat- 
son 412, iu part); Oregon (Hall 203), “Wappatoo Island” (NuilalX), Union 
Co. (Cusiek); Vancouver Island and N. W. Territory (Maeoun, in 1887). 
This has been much confused by collectors with specimens of EulopJnis 
(Podoseiadium), ^speeisiliy E. Bolanderi; hence this species is very scarce 
in herbaria. 
3. C. Kelloggii Gray, Proc. Am. Acad. vii. 344. Resemb- 
ling C. Gairdneri, but somewhat stout, from a fascicle of thick- 
ened fibers, with lower leaves ternate or biter nate with pinnate 
divisions and linear segments: involucre and involucels more prom- 
inent and rather scarious: fruit larger, oblong, Ij^ to 2^2 li'it;^
