82 BR. J. D. HOOKER OX TIIE FLORA 



Islands and Bank's Land (lat. 71°-75°), I find the following in 

 Dr. "Walker's which are absent in the Western Islands : — 



Luzula arcuata, Wahl. 

 Pleuropogon Sabini, Br. 

 Phippsia algida, Br. 



Stellaria humifusa, Rottb. 

 Arenaria verna^ L., var.(rubella, Br.). 

 Saxifraga rivularis, L. 

 Juncus biglumis, L. 



Of these, the Pleuropogon and Phippsia are the most peculiarly 

 Arctic plants ; the others, except the Stellaria, were more proba- 

 bly overlooked in Bank's Land, though the collections from there 

 appear to be so complete that this is hardly likely.
