54 ON THE BOTANY OF THE BRITISH POLAR EXPEDITION. 



After each plant, besides its distribution amongst these districts, 

 letters E, W, or G may be found ; these roughly divide the whole 

 area visited into three well-marked sections. 



E indicates east shores north of Humboldt Glacier, and of 

 80° lat. (Districts 10 and 11). 



W indicates west shores visited, all north of 78° 45'. Elles- 

 mere Land and Grinnell Land. (Districts 6, 7, 8, 9, 12, 13). 



G indicates Greenland station visited, south of Humboldt 

 Glacier and of 78° 13' lat. (Districts 1, 2, 3, 4, 5). 



I. Egedesminde ; lat. 68° 42'. Sept. 29 to Oct. 2, 1876. 



We visited this island when homeward bound, and the season 



was too far advanced for successful botanising. It is a low-lying 



granitic island, or rather series of islands, very barren and exposed. 



There is here little soil or sheltered valley-ground to harbour plants. 



At the date of our visit most of the Eric ac em, Pyrola, Cerastium 



alpinum, Polygonum viviparum, and a few grasses, were still in flower. 



I noticed here Polygonum aviculare in small quantity near the 



settlement, perhaps a colonist, and a few stunted plants of Saxifraga 



stdlaru were gathered. I also picked a leaf which, I feel convinced, 



belonged to Viola palustris, the only representative of its family 



found in Arctic Greenland. These latter three were not observed 

 elsewhere. 



Disco, lat. 69° 15', July 6 to 15, 1875, and Sept. 25 to 29, 1876. 

 This is the best explored botanical locality in all Greenland, 

 but my experience leads me to believe that its resources are by no 

 means perfectly known. A week's collecting upon the island 

 of Disco, m 1875 (Disco botany was quite over at the time of our 

 visit in 1876), yielded 119 species. R. Brown, in his 'Florula 

 Discoana ' (which comprises a district ranging over nearly a degree 

 and a half of latitude, and lying mostly to the north of Disco, and 

 is the result of over three months' exploration), enumerates one 

 hundred and twenty-nine plants, of which about sixteen are mere 

 varieties ; and many are from the mainland and more southern 

 localities. My list contains about twenty-eight species from Disco 

 not mentioned in Brown's list. If we deduct from Brown's total 

 sixteen varieties, and about eight which are only found south 

 ol Disco, and probably do not occur there, we have a residue of one 

 hundred and five ; adding to these twenty-nine in my list, and 



oecurrin 



north and south of Disco), we may place the Flora of Disco at 

 about one hundred and fifty-eight vascular plants. 



Ihe following species do not appear to have been previously 

 obtained in Disco : — r

 therefore, be expected to occur in AYest Greenland
