Hab. Nortb-West coast of America. Douglas. — A solitary specimen of this plant is all that I have 

 had the opportunity of seeing. In habit, it resembles the genus Carthamus ; but from the structure of the 

 floscules, and especially of the stigmata, I can have no hesitation in referring it to Eiipatorinem, near 

 Liatris. The pappus, even in the state of early flower, is remarkably long and tawny, inclining to red. 

 Tlie leaves, when held up between the eye and the liglit, exhibit numerous pellucid dots, which appear to 

 be the areolae of the obscure reticulations.

Very few of the specimens gathered by Dr. Richardson have leaves exactly answering to the above 



character, and of these, some are nearly ten inches long, independent of the petiole.
