n working at a flora of the higher plants of Disco, I have 
found on that island a relatively great contingent of southern 
types; most of these occur isolated, i. e. their stations on Disco 
are separated from those on the continent of West Greenland by 
various distances, up to 8 degrees of latitude. In ascertaining those 
facts, I was obliged to revise the previous statements, as they do 
not always give the limits of distribution as exactly as needed, and 
in addition, I have occasionally investigated the adjacent districts 
myself and thereby been able to add some species to those previously 
known to occur there. Moreover I have found new localities, and 
what is of more importance still I have obtained a fairly reliable 
knowledge of what species are common and what rare, and of the 
distribution of the commoner plants. 
The investigations of the district embraced in the following list 
have been of different values; particularly the gneissic region at 
the NE. corner of Disco Bay has only once been cursorily investi- 
gated by BERGGREN. The principal reason for including the plants 
found by him in the present list is that BERGGREN found in the 
locality in question some southern types, otherwise not known 
from the distriet: Potentilla Ranunculus, Draba incana, Arctostaphylos 
alpina and Gnaphalium supinum. Probably a closer examination, 
especially of the head of the Store Dal near the lakes, would yield 
some additional species. 
Previous investigations and literature. J. VAHL travelled 
through the Waygat in 1835 and 1836. His collections were published 
by Тон. Lance in his Conspectus florae Groenlandiae (Meddel. om 
Gronl. Ш. 1880). Вов. Brown (of Campster) collected plants along the 
shores of Disco Bay, 1867 (Trans. Bot. Soc. Edinb. IX. 167—68); 
Е. NorDENSKIOLD and Sy. BERGGREN, 1870 (Öfv. Kungl. Vet.-Ak. Förh. 
1871. No. 7. Stockholm); TH. Fries, 1871; А. G. NATHORST, 1883 
(Öfv. Kungl. Vet.-Ak. Férh. 1884. No. 1. Stockholm). N. Harrz 
collected plants along the shores of Waygat 1890 (Meddel. om Gronl. 
15. 1898). Most of the contributions from the above-mentioned
