Atropis Vahliana should be added to the list also, if not its appearance in 
Ellesmereland made it more probable that its right place is anioiig the american 
species distributed southward in Greenlaiid, whereas Mcrtensia maritima, Vaccinium 
Vitis id(Ba, *PofenfiUa nivea, * Arabis BooJceri, and *Betula nana, show a similar 
distribution with a southern limit on the west coast, but have reached north of 
Melville Bay. Others again, such as ^PedicuJaris flammea, *Bortsia alpina, and 
*Rhododendron lapponicum, are distributed all over western Greenland beyond Mel- 
ville Bay without a corresponding area to the west. No less than 141 american 
species are found in Greenland, without being recorded from the Archipelago; of 
these 25 are restricted to the southern part of the west coast, 92 range from the 
south over most parts of Danish Greenland, 5 reach north of Melville Bay, 19 
have an area in inid.llc Danish Greenland, with a southern as well as a northern 
limit on that coast; 104 of tliein show a more or less corresponding distribution on 
the east coast. It niay be veiy probable that some of these will some time be found 
in Baffin Land, and perhaps in other parts of the Archipelago also, but still there will be 
a considerable element left, the appearance of which is quite as difficult toac count 
for as that of the species from the Archipelago, mentioned above. Moreover, we have 
13 european species with a range from the neighbourhood of Cape B^arewell more or 
less far north on the western coast, and of them 9 appear on the eastern side also. 
Restricted to the birch-region of southern Greenland are 36 species, 26 american 
and 10 european, to which Matricaria inodora can be added, as far as its range 
on the west coast is concerned, but on the eastern side it appears only considerably 
farther north. These southern elements, as already mentioned, ought to be excluded 
from com parisons with the Archipelago, and, moreover, many of them most probably 
are introduced by man, either in the last years or during the time of colonization from 
Iceland. Most, or perhaps all the 10, european species of southernmost Greenland 
appear near the old places of habitation, and among the 26 reckoned as american 
only a very small number is absent from Europé, most of them being Iceland plants. 
Northern East Greenland shows a very curious eastern element of its own: 
Carex parallela, Draba repens and Taraxacum arcticum, totally absent from America, 
while Braya ylahella, Dryas octopetala, Saxifraga hieraeiifolia, and Polemonium horeale, 
found far to the southwest in America, here certainly are to be looked upon as eastern 
immigrants. To these may be added Matricaria inodora, but I look upon Saxifraga 
Hirculus as an immigrant from the west, as previously discussed. Finally Raniin- 
culiis glacialis has a wider distribution southward along the east coast, where Sedum 
acre is added. Thus the east coast gets a contingent of 10 eastern species of its 
own. But the total number of species now known from East Greenland amounts 
to 268, and even with the addition of 9 species which the southern parts have in 
common with the corresponding region in West Greenland, we do only get an 
eastern contingent in the flora of 7 pct., while the western (american) can hardly be 
reckoned as amountiug to less than 25 pct. I am, indeed, inciined to accord a far 
higher figure to it; takiug for granted that the Arctic Islands have not had any
