142 Merriam Plants of the Pribilof Islands. 



Artemisia globularia Cham. 



Common in places on St. Paul, particularly about Polavina. 

 St. Paul is the type locality of this species. 



[It has rarely been collected, and until now has been a desid- 

 eratum in the National Herbarium. J. N. R.] 



Artemisia norvegica pacifica Gray. 



Specimens determined by Mr. Rose as belonging to this sub- 

 species were collected on both St. Paul and St. George, although 

 the forms inhabiting the different islands are distinguishable. 



[The type form of A. norvegica, or at least the Rocky Moun- 

 tain plant which passes as such, is common upon St. Paul. 

 Gray, in the Synoptical Flora, does not extend the range of the 

 species so far north. The stems are [200-805 mm.] 8 to 12 

 inches high, nearly erect, and very villous (as are also the 

 leaves) except near the base. On St. George occurs a nearly 

 glabrate form, which answers to the var. pacifica. J. N. R.] 



Artemisia vulgaris tilesii Ledeb. 



Collected near Bogoslof hill, on St. Paul, and near the village 

 on St. George. 



[On St. George Island occurs A. vulgaris, var. tilesii, but the 

 heads are so much larger than A. vulgaris that I am inclined to 

 the opinion that this form should have been kept distinct. The 

 form from St. Paul Island, although similar, has somewhat 

 smaller leaves, and these are white-lanate on both sides.

Petasites frigida Fries. 

 Tolerably common on St. Paul ; past flowering by August 1. 



Senecio pseudo-arnica Less. 



Common on St. Paul ; just coming into flower the first week 

 in August. 



Taraxacum officinale lividum Koch. 

 Not very common on St. Paul ; in flower early in August. 



Campanula lasiocarpa Cham. 



Common in places on St. Paul, particularly in the drier moss 

 plains ; flowers large and handsome.
