linear divisions : petals often wanting, sometimes 1 only, or 

 5, large, broadly obovate or more rounded, bright yellow : 

 achenes very numerous, plump, smooth, tipped with a short 

 curved style and disposed in a large globose head. 



Lower and middle mountain districts of Colorado, Utah 

 and Nevada to eastern California. Very nearly allied to i?. 

 glahen-imus, though a smaller plant, and inhabiting a differ- 

 ent climatic belt. There is a difference in the achenes ; those 

 of the true glaherrimus having a slender beak. The order of 

 leaf-division is, moreover, inverted in the two species. In E. 

 ellipticus the cauline are 3-cleft while the radical are entire 

 and even acute. In E. gluherrimns the radical ones are 

 broad and broadly 3-lobed while the cauline are entire. The - 

 herbage of the latter invariably blackens in drying, lu the 

 former it undergoes no change of color.

 Island, where I saw and made notes upon the trees in front 

 of the dwelling of the late Sir James Douglas, one of which 

 is on record as being the type of Mr. Brown's species. 



By reference to Mr. Brown's notes, reprinted by me, it will 

 be seen that he credits both this and its ally, Q. Garryana, 

 to the h^cality ; in which opinion it is plain to me that he is 

 in error. The two more than middle-sized trees on Sir
