(.'alyx deeply r)-cleft, the lobes usually broad and rounded. Corolla short, with a 

 ventricose globular or oblong tube, unequally 5-lobed ; 4 of the lobes erect (the two

 Oregon. It may therefore occur in the northern jtart of the Stiite. It is distinguished by 

 the larger and orbicular sterile stamen-rudiment, and the leaves are merely serrate, rarely at all 

 incised.
