C. trichosperma, although he is, we think, wrong in making 

 it a variety of that species. 



About 3 feet high, erect, branching but little, bearing 

 towards its summit a few showy heads of flowers. Leaves 

 linear, pubescent, 3-5-parted, serrated, opposite. Rai/s 8, 

 oblong, nearly entire, bright yellow, three times as long 

 as the involucrum. Fruit wedge-shaped, nearly smooth, 

 2-horned at the end.
