COMPOSITAE (COMPOSITE FAMILY) 499 
and thin; the leaves are thrice pinnatifid, the segments finely 
divided and again cut and lobed; lower ones with slender petioles, 
but upper ones sessile or nearly so. Flowers in loose compound 
racemes, often more than a foot in length, the branchlets exceed- 
ngly slender and closely strung with nearly globular, nodding 
heads less than a sixth of an inch in diameter. These small, 
dried heads are called “seed,”’ though of course they contain a 
aumber of very small achenes. 
Means of control 
Prevent seed production by frequent close cutting during the 
srowing season; if this is done, unless the ground is foul with 
lormant seed, the weed will disappear. 
PASTURE SAGE

Texas and New Mexico. 
Habitat: Grasslands. 
Closely grazed pastures are sometimes badly overgrown with 
his weed, for cattle will not eat the bitter foliage and the plant is 
eft to reproduce itself. 
Stems tufted, ten to twenty inches tall, smooth, woody at the 
vase, the younger parts silky white with soft hair. Leaves also 
lensely silken-hairy, grayish green, a half-inch to nearly two 
nches long, three- to five-parted, the segments very narrowly 
inear; lower leaves have slim petioles, often.with a pair of entire 
w three-cleft divisions near the base; upper ones have fewer seg- 
nents and are sessile. Heads very numerous in narrow terminal 
yanicles; nearly hemispheric, about an eighth of an inch broad, 
1odding on short pedicels ; involucral scales rounded oblong, silky- 
iairy. Only the central florets of the heads are fertile.
