1898-1902. No. 16.] FLOW. PLANTS AND FERNS OF N.-W. GREENLAND. 27 



The 108 species belong to the families included in the above 

 table, of which each is represented by the number of species mentioned 

 in the column for N. W. Greenland. The corresponding figures for N. E. 

 Greenland and Ellesmereland are added to facilitate comparisons. 



Already from the above table it appears that there is a consider- 

 able conformity between the floras of the three districts here compared. 

 The genera with the greatest number of species, are also nearly the 

 same in N. W. Greenland as in Ellesmereland; viz. Saxifraga (11) 9, 

 Carex(l\] and Ranunculus (6)6, Pedicularis (4), Draba (5) and Poten- 

 litla (4) 5, Glyceria (4) 4. The figures in () represent the number of 

 species in Ellesmereland, where also Poa has 5 species (only 3 in 

 N. W. Greenland). Carex indeed appears to be far less represented in 

 the flora of N. W. Greenland, than in that of Ellesmereland or of 

 N. E. Greenland, where it reckons 13 species; but that most probably 

 is accounted for by the less accurate exploration of the first-mentioned 

 region, rather than, as HART thinks, by a more arctic climate (Bot. Br. 

 Pol. Exp., p. 9). 



Before, however, I go into further detail, I think it will be best to 

 facilitate the survey of the floras of N. W. Greenland and the neigh- 

 bouring lands by the following tabulated statements of the distribution 

 of the species (Table III). All the species found with certainty, either 

 in N. W. Greenland, N. E. Greenland, or Ellesmereland, are inserted 

 here; and further, their appearance in Danish West Greenland, in the 

 Arctic American Archipelago, or in the arctic parts of the American 

 Continent indicated. In the first column, that of Danish West Green- 

 land, a"- ' before the figur of the approximative degree of limit, signifies 

 that the species is spread so far south; after the figure, it signifies the 

 northern limit of the plant so far as known; the sign "- " by itself, signifies 

 that it is spread along the whole coast. In the N. E. Greenland 

 column, the signs are used in the same manner. The distribution, how- 

 ever, south of Scoresby Sound is left entirely out of consideration as 

 being of no interest here. An "S" signifies that the species is not found 

 north of Scoresby Sound. As previously mentioned, I have only taken 

 up in the list, such E. Greenland species as are found from Cape Hold 

 with Hope (Broer Ruys) northward if they are not already entered as 

 N. W. Greenland or Ellesmereland plants. 



In the column for N. W. Greenland, "S" signifies occurrence south 

 of the Humboldt Glacier, "N" northward from there. A " + ' is used 

 for species found only in a single place. In the Ellesmereland column, 

 "S" is used as the sign for occurrence in the southern, "N" in the
