HOOKER, BOOTHIAN PLANTt\ 525 



In Melville Island the following species occur which were not 

 found by Dr. Walker at Port Kennedy : — 



Eanunculus hyperboreus,Rottb., Sieversia Rossii, Br. 



var. (Sabini, Br.). Taraxacum officinale, DC. (var. 

 R. auricomus, L., var. (affinis, palustre). 



Br.). Arnica montana, L. 



Caltha palustris, L., var. (arc- Senecio palustris, L., var. 



tica, Br.). (Cineraria congesta, Br.). 



Draba Lapponica, DC. Nardosmia corymbosa, Hk. 



Parrya arctica, Br. Antennaria alpina, Br. 



Cardamine bellidifolia, L. Deschampsia caespitosa, P.B., 

 Stellaria longipes, Goldie (Ed- var. (brevifolia, Br.). 



wardsii, Br.). Trisetum subspicatum, P.B. 



Phaca astragalina, DC. Hierochloe alpina, R. & S. 



Oxytropis Uralensis, DC. var., H. pauciflora, Br. 



(artica, Br.). 

 Chrysosplenium alternifolium,L. 



The Port-Kennedy plants not found in Melville Island are the 

 following : — 



Epilobium latifolium, L. Pedicularis capitata, Ad. 



Chrysanthemum integrifolium, P. hirsuta, Willd. 



Rich. Salix reticulata, L. 

 Cassiopeia tetragona, Don. 



On the western shores of Baffin's Bay, between Pond's Bay 

 and Heme Bay, the following Port-Kennedy plants appear to be 

 absent : — 



Stellaria humifusa, Rottb. Pedicularis capitata, Ad. (Wes- 



Saxifraga flagellaris, L. tern limit). 



Pedicularis sudetica, L. Dupontia Fischeri, Br. 



Lastly, comparing Dr. Walker's Port-Kennedy collection with 

 Dr. Anderson's and Herr Miertsching's from the Western Polar 

 Islands and Banks Land (lat. 7l°-75°), I find the folloAving in 

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



Stellaria humifusa, Rottb. Juncus biglumis, L. 



Arenaria verna, L., var. (ru- Luzula arcuata, Wahl. 



bella, Br.). Pleuropogon Sabini, Br. 



Saxifraga rivularis, L, Phippsia algida, Br. 



Of these the Pleuropogon and Phippsia are the most peculiarly 

 Arctic plants. The others, except the Stellaria, were more pro- 

 bably overlooked in Banks Land, though the collections from 

 there appear to be so complete that this is hardly likely.
