which suggest any affinity of these plants with the Eupator- 

 iacere; for the corollas are neither purple nor even ochro- 

 leucous, but deep yellow; and authors appear to have over- 

 looked altogether the shape of the akene, which is wholly 

 that of the Helianthoidea3. The style-tips, moreover, are 

 those of that tribe, and not of the one to which the Atlantic 

 genus, Carphephorus belongs. Both the striate involucres,, 

 and the plumose pappus are found in other Helianthoid 

 genera. Yet the place for this genus is not near either 

 Blepharipappus or Blepharizonia, whose involucral scales are 

 uniserial. It is nearer to the subtribe Verbesineie by its 

 much imbricated involucre, as well as by the roughness of 

 its herbage, sunflower-like odor and general habit. Doubt- 

 less it ought to constitute a distinct subtribe, to come in 

 between those here named. The genus is dedicated to Mr. 

 Michael S. Bebb, of Rockford, Illinois, an able botanist, to 

 whom all students of the science on the Pacific Coast are in- 

 debted for the careful elaboration of our species of the difficult 

 genus Salix, in the second volume of the Botany of California.

This plant grows in perfection on Cedros Island, in ar- 

 royos near the sea, where it commonly attains the height of 

 six or eight feet, its lithe, woody stems supporting them- 

 selves amid the branches of Rhus Lentil, or more frequently 

 uniting with the similar looking Antirrhinum junceum to 

 form large, impenetrably dense reedy masses as broad as 

 high. The stems are nearly leafless and rather smooth, and 

 the heads solitary and a good deal larger here than within 

 the limits of the United States; but this southwestern form 

 is the type of the species. The following may eventually 

 prove distinct, namely: 



Var. aspera.
