ON THE BOTANY OF THE BRITISH POLAR EXPEDITION. 115 



Floeberg Beach differed in size or luxuriance from similar species 



growing at Discovery Bay ; though the entire failure of so many 



plants in so few miles of latitude is worthy of consideration. I 



thing I may safely say that Oxyria reniformis was the plant which 



grew most luxuriantly at the highest elevation around Floeberg 

 Beach. 



With reference to the above remarks, it is well to observe that 

 it is due to the configuration of the land that northern slopes 

 obtained the greatest amount of sun's heat in Captain Feilden's 

 latitudes. Eastern and southern slopes are the most favoured 

 around Discovery Bay. 



To the many kind friends and botanical correspondents who 

 have given me valuable assistance in the preparation of these 

 notes my warm acknowledgments are due, especially to Mr. J. G. 

 Baker, of Kew, who has most kindly compared and identified for 

 me many of the critical forms, and to the officers of the Dublin 

 Museum of Science and Art, who have given me every facility for 

 carrying on my studies in their Natural History Department. My 

 friend Mr. A. Gr. More has continually given me the benefit of his 

 valuable advice, and rendered me every assistance in his power. 



To Sir Joseph Hooker I am indebted for details respecting the 

 distribution of several Arctic species, and for encouraging me to 

 proceed in my laborious undertaking. 



The Bev. J. E. Leefe has very kindly examined all the specimens 

 of Salix gathered by our Expedition to which I have had access in 

 Dublin, with the result of referring all the higher northern forms 

 to S. arctica. 



My colleague, Captain Feilden, has kindly placed at my 

 disposal his notes upon the plants of Floeberg Beach and other 

 localities north of those visited by me. 



My results are chiefly drawn from my own memoranda, made 

 during the voyage, and the specimens collected by me, now incor- 

 porated in the Herbaria at Kew and in the British Museum. In 

 addition, I have fortunately been able to consult the valuable 

 botanical collections made by Dr. Moss, of H.M.S. ' Alert,' from 

 Disco to Floeberg Beach, now deposited in the Herbarium of 

 Trinity College, and placed at my disposal by Dr. E. P. Wright, 

 the Professor of Botany. I have also carefully studied an 

 interesting series of specimens collected by my shipmate, Dr. 

 Coppinger, to whom I am mainly indebted for the knowledge of 

 the Flora of Polaris Bay, where he was encamped for several 

 weeks during the summer of 1876. With these are incorporated 

 a collection made by myself in Discovery Bay, the whole being 

 now deposited in charge of the officers of the Natural History 

 Department of the Dublin Museum. 



To Dr. Steele my sincere thanks are due, for his kindness in 

 allowing me to examine a most interesting series of Arctic plants, 

 which were chiefly made during the various Franklin Search 

 Expeditions.
