144 Merriam Plants of the Pribilof Islands.

Common at Northeast Point and along some of the gravel 

 beaches elsewhere on St. Paul. In full flower the latter part of 

 July. 



Pedicularis langsdorffii Fisch. 



One of the most abundant and conspicuous plants on both 

 islands. Grows in large patches and presents such a diversity 

 of forms as to suggest several species. Flowers past prime by 

 end of July. 



Gymnandra gmelini Cham. & Schl. 



Collected at the mouth of Bogoslof cave on St. Paul August 7, 

 where it was common and past prime. 



Oxyria reniformis Hooker. 



Rather common in places, particularly about Bogoslof hill on 

 St. Paul. 



Polygonum viviparum Linn. 



Abundant on both islands ; past prime. 



The willows have been determined by Mr. M. S. Bebb as 

 follows : 



Salix arctica Pallas. 



Collected on Polavina moss bogs, St. Paul, August 8. 



Salix phylicoides And. 

 Collected at Bogoslof hill, St. Paul, August 7. 



Salix reticulata Linn. 



Abundant on both islands, growing in dense mats on the bogs. 

 Though the branches are long, they are prostrate and buried in 

 the moss, so that the highest leaves rarely reach more than 70 

 or 80 mm. (21 or 3 inches) above the general surface of the bog.
