 involucral bracts (as of the next following group) all close and unappendaged, the outer suc-

• A. ClineatUS, Ojjay. Slirub a foot or so high, intricately branched and spreading, bal- 



.saniic-ghitiuous : leaves thick, cmieate or rarely obovate, retusc, sometime? apiculate, entire 

 but inclined to be imdulate, usually resinous-punctate, 2 to 4 lines long, larger ones petioled : 

 heads corymbosely fasciculate, 5 or 6 lines long : involucre turbinate ; bracts lanceolate or 

 nearly linear, rather obtuse: rays 2 or 3, or solitary and small, or as commonly wanting: 

 style-appendages slender-subnlate, not longer than the stigmatic portion : akeues pubescent.
