(Chamddis artemiscefblia, Gray.). Flower 

 heads white, without ray florets, the involucre sticky to the 

 touch, borne on naked peduncles in loose, leafless panicles. 

 Leaves alternate, about 4 inches long, twice or thrice divided 

 into very narrow divisions, more or less sticky-hairy. An up- 

 right, branching annual, from 1 to 5 feet high* common in the 

 hills of some parts of Southern California from the vicinity of 

 Los Angeles to San Diego, and southward into Mexico; bloom- 

 ing April to July. 



In default of a popular name, the by no means hard botan- 

 ical generic name (pronounced Ke-nac'tis) may serve. Chaen- 

 actis means " a gaping ray," and was given to the genus because 

 in most species the ray florets are enlarged into a sort of wide- 

 open mouth. This character, however, is not obvious in this 

 species. 



There is another white-flowered species, but with marginal 

 florets much enlarged, quite common on the Colorado Desert 

 of California and eastward to Arizona ^Chcenactis FremiSnti, 

 Gray. It is a rather slender annual, sometimes only a couple 

 of inches high, and rarely more than a foot tall.
