 — Uraguay. Baird. — Difficult as it may be, in words, to describe 

 correctly the varied forms of the leaves of this genus ; those of 

 this plant are very distinct from any others; they are almost 

 exactly elliptical except at the base; and the apex only, or for 

 not more than one-fourth of the way down, is moderately 

 serrated with equal serratures. The capitula occupy the 

 axils of several of the rather remote leaves in regular succes- 

 sion, and are completely sessile and constantly solitary. 

 Pappus (female plants) tawny, half as long again as the in- 

 volucre. Styles slightly exserted,

 copious harsh leaves, scarcely an inch long. The flowers are 

 in a very imperfect state, but the plant seems to be decidedly 

 a Baccharis and very distinct in its characters.
