54. SEN EC 10, Linn 



1. Senecio aureus, Linn. 



Hab. Interior of Washington Territory, at various stations; the 

 typical form, and a state of the var. Balsamitce (S. Plattensis, Nutt.) 

 from Okanagan ; also the var. borealis, from the eastern side of the 

 Cascade Mountains. 



2. Senecio canus, Hook. 



Hab. Interior of Washington Territory ; forms approaching states 

 of the last, much as do forms of the analogous S, tomentosus along the 

 Alleghanies. 



3. Senecio fastigiatus, Nutt 



Hab. Between Spipen River and the north fork of the Columbia. — 

 Certainly identical with NuttalPs plant, but probably an entire-leaved 

 form of S. canus. 



4. Senecio exaltatus, Nutt 



Hab. Between Okanagan and Grand Coulee, Washington Terri- 

 tory. — Probably a mere variety of S. lugens, which occurs in the 

 Rocky Mountains a little further north.

 fornia.
