Henderson)-, Waslunglou Toiritory, Falcon Valley (SuksdorJ^, Spokane 
River (Oeyer 581), in part); Idaho, Oceur d’Alene {Geyer 583, in part). 
Numerous very immature specimens of this species are found in her- 
baria, in which the bracts seem very prominent, but it is simply owing to 
the immaturity of the heads. 
’ Var. microcephalum. A small slender form, with short 
ovate acuminate bracts (with somewhat spinulose margins) but 
little longer than the very small heads (2 or 3 lines in diameter), 
and calvx-lobes short-mucronate. 
Plumas county, California, 1878 {Mth. R. M. AusHn). 
The bracts have a bluish tint. 
14. E. Harknessii Curran, Bull. Calif. Acad. iii. 158. Like 
the preceding, but much simpler and taller, about 2 feet high; with 
much larger ovate-oblong heads (half inch or more long) exceed- 
ing the bracts; the prominent bractlets blue. 
California, Suisan Marsh, August (Bolander, in 1864, Harkness, in 
1 883), shores of Goose Lake, September, 1884 (in herb. Martindale,- labeled 
E, petiolafum); also probably, Washington Territory, Spokane Riv*r 
(C'ooper); also collected by Aea’herrj!/ in Survey of California and Oregon, 
with neither station nor date. 
15. E. aromaticum Baldwin; Elliott, i. 844. Stems de- 
cumbent or erect, several from one root, simple to near the sum' 
mit, very leafy, 1 to 2 feet high: leaves pinnately parted, with 
entire segments and cartilaginous margins; the 8 ujDper segments 
remote and broader, cuspidate; the lower ones scattered and seta- 
ceous: heads globose (about 5 lines long), with involucre of 8-cleft 
bracts longer than the head, and 8-toothed bractlets: fruit tuber- 
culate, half a line long, with setaceous calyx-teeth a line long, and 
long styles: oil-tubes large, 8 dorsal and 2 commissural: seed flat- 
tened dorsally, with plane face. (Fig. 108.) 
Dry pine barrens, Florida; also near Ft. King, Alabama (Li. Alden, In 
1833). FI. August and September. / 
16. E. foetidum L. Spec. 282, in part. A foot or more 
high (said to be heavy-scented), branching above: radical leaves 
oblong, spinulose-serrate; upper leaves sessile, palmately cleft with 
segments more or less cuspidate-toothed: heads oblong (about 
8 or 4 lines long), sessile, with involucre of large leaf-like bracts 
many times longer than the head, deeply palmately parted into 
lanceolate more or less spinosely-toothed segments; bractlets
