Series 2. Eupatoriacese. — Style-branches bluntly clavate, rarely cylindrical -filiform, pu- 

 berulous above the sfigmaiic lines, or glabrous. Heads discoid, homogamoas, cyanic. — 

 Leaves usually opposite. 



In this series the cohesion of the anthers is generally slight, and in some cases (as in 

 Adenostemma, Brickelia diffusa, Hebeclinium, etc.) the anthers in dry specimens appeared 

 quite distinct, as was stated before of Kuhnia : but tbis k of no generic importance.
