number of these are woody. They have, especially when bruised, a 
strong pungent odor, pleasant in some species and disagreeable in 
others. The glandular herbage varies in palatability from worth- 
less to poor. 
Prairie dogweed (LD. papposa, syns. D. chrysanthemoides, Boebera 
papposa), also called dog fennel or fetid-marigold, an annual herb 
now found-natively or as an introduced weed in the great majority 
of the States, is, according to R. F. Copple, fair horse feed in parts 
of northern New Mexico where stockmen claim it will remove bots 
from the stomachs of infested animals. D. papposa in most places 
is worthless, or at best poor, as forage and Pammel (95) claims that 
“it is probably injurious.” 
Prickleaf (LV). acerosa, syns. Aciphyllaea acerosa, Hymenatherum 
acerosum), a small, bushy, rather agreeably scented plant 4 to 12 
inches high with very fine, glandular, pricklelike leaves, thick woody 
taproot, and branched woody crown, occurs on low dry hills from 
western Texas to southern Nevada and south into Mexico. It is 
wholly unpalatable and in some places is abundant enough to 
become a range pest. 
Sneezeweed Tribe (Helenieae) 
Damianhita (Chrysactinia mexicana), a low, heathlike, profusely 
branched, aromatic shrub with evergreen, gland-dotted leaves oc- 
curs from western Texas to New Mexico and south into Mexico, in 
brush or grass-browse associations up to the woodland and lower 
yellow pine types, usually in scattering stand. It is not known to 
be grazed, but should be closely watched on range where it is com- 
mon, as it obviously has active properties and is a medicinal plant 
with Mexicans and Indians. The shrub is often called damiana, 
but the officinal damiana belongs to the genus Turnera. 
Yerba-del-venado (Porophyllum gracile), sometimes called slen- 
der poreleaf, occurs on warm, mostly dry plains at low elevations 
from Lower California to southern California and western Texas 
and south into Mexico, and is sometimes very plentiful, especially in 
sandy situations, such as beaches, dunes, and alluvial strands. It is 
a bush 6 to 40 inches high, with a strong odor reminiscent of rue or 
fennel. Despite the astringent properties of the herbage Goldman 
(45) reports that residents of Lower California state that deer and 
cattle are very fond of this plant, and Palmer has recorded its 
medicinal use in that region (139).

SAGEBRUSHES (ARTEMISIA SPP.) 
The genus Artemisia is a large cosmopolitan group of aromatic 
herbs and shrubs of both hemispheres, embracing probably about 
250 species. The greater part of those in the Western Hemisphere 
occur in western North America, the center of distribution being 
in the Rocky Mountain region, to which Rydberg (207), attributes 
72 species, 9 being true shrubs, 44 more or less undershrubby, and 
19 true herbs. 
There seems to be no generally recognized English equivalent of 
Artemisia. In the West, however, these plants are, as a rule, gen-
