Two floral districts of the Nordostbugt. 
The strongly marked difference in West Greenland between the 
floras of the coast-land and of the head of the fjords has been touched 
upon by several botanists, e.g. RosENviNGE (24), Porsizp (19, 20), 
Kruuse (9), Hartz (4) and others. On the other hand climatological 
data are very scarce and from a typical fjord we have but one set of 
data cited by RosENVINGE (24, рр. 94—95) from Godthaabsfjord where 
the mean temperature of July in a distance of only 50 km. rises 1.2° C. 
In spite of the incompleteness of the meteorological data”) from the 
Nordost Bugt they provide two interesting pieces of informations: 
1) that generally speaking the climate of the Nordost Bugt has a 
more continental character than that of Jacobshavn at the head 
of the more open Disko Bugt; 1. e. colder winter and rather warmer 
summers and, in addition, less fog and precipitation. 
2) that there is also a pronounced difference between the climate of 
the outer coastal area facing the open Davis Strait, represented 
by data from Igdlorssuit at Ubekendt Ejland, and that of the 
inner area represented by Ikerasak near the inland ice. In the 
latter area the mean of July may even rise 2° higher than at 
Igdlorssuit. 
In the following table I have tried to express in figures the influence 
of climatic differences on the composition of the floras of the two areas. 
Our incomplete knowledge creates a difficulty and I have therefore 
chosen to select a few of the best known local floras within each area?). 
The flora of the outer area is thus represented by: 1) the south coast 
of Svartenhuk peninsula, 71°25’, by 2) Igdlorssuit 71°14’, by 3) the 
trading place Nûügssuaq, 70°38’, by 4) Hare ©, while the inner area is 
represented by 1) the south coast of Upernavik Ejland, 71°10’, by 
2) Ikerasak and environs, circa 70°30’, by 3) Naujat, 70°, at the south 
coast of the Nugssuaq peninsula. 
It must here be mentioned that all the localities in the outer area 
lie within the basalt region, while within the inner area gneiss, sand- 
stones as well as basalt are present. This may well produce some dis- 
crepancy for example, as to the acidity of the soils, and I have no doubt 
that, at least a few species do not occur on basalt at all and vice versa. 
Stil I do not think this will affect the actual numbers to any great

2) In this list 7 species do not occur: they are all from stations on the boundary 
between the two areas. The species are: Potentilla Egedii, Limosella aquatica and 
Plantago borealis all southern types; Poa abbreviata, Ranunculus affinis and Tarax- 
acum phymatocarpum, northern types, and Carex holostoma, a widely distributed 
type. Thus the total number of species in the two areas should be 194.
