to the ice-age when all Greenland was covered by ice. If this supposition 
is correct, having regard to the great length of the coast-line, 16 is sur- 
prising to find 150 species or about 71 p.c. of the total flora common 
to both regions. 
Also if we divide the flora into groups of northern, widely distri- 
buted, and southern types the numbers reveal a close agreement:

i.e. the most marked difference is presented by the arctic element. 
Together with numerous other valuable notes on the flora of Scoresby 
Sound Harrz (loc. cit.) has given the maximum vertical range for 
nearly all the species of vascular plants, and I have tried to compare 
these ranges with those known from the west coast of Greenland, 
especially those within the same parallels. Unfortunately our available 
information on this point is still very incomplete and all such records 
can only he considered as preliminary. 
In LANGE's: Conspectus Fl. Grl. numerous records of this kind are 
given, but, as remarked by LANGE (11) himself, mostly without any 
information as to the latitude or local conditions. As the absolute max- 
imum, vertical range cannot reasonably be expected to be the same 
on the latitude of Julianehaab and of Upernavik, such records are 
consequently not of much value. 
In the summary given below I have tried to compile the records 
of vertical ranges of vascular plants from W. Greenland and, in a separate 
column, those from Scoresby Sound. My sources have principally been 
LANGE's: Conspectus with appendices of which only the last, edited by 
ROSENVINGE (23), gives any information on latitude etc., also War- 
MING (30), Rink (22), Hartz (4, 5) and Porsirn (16). In brackets I
