The following notes on the Arctic Ericineæ were for the most 
part published as early as 1885—86 in Botanisk Tidsskrift 
(Köbenhavn); Det Kgl. Danske Videnskabernes Selskabs 
Oversigt; and Det Kgl. Svenska Vetenskaps Akademiens 
Bihang. But as they were written in Danish, they have been but 
little used by foreign botanists. They have now been collected 
and published in the presefit (36 th) volume of Meddelelser om 
Gronland in English, after having been supplemented by addi- 
tional observations and figures, some of which are old, but have 
not hitherto been published, while some are new, having been made 
during the present year (1907) and based upon the rich material 
belonging to the Botanical Museum in Copenhagen. 
The present notes are the first of a series upon the structure 
and biology of the Arctic flowering-plants which will probably be 
published by me and by several other Danish botanists; the object 
of publication is that they may serve as a basis for subsequent 
botanical studies by those who may work in Arctic countries, and 
who may thereby be enabled to make biological observations on 
the spot more quickly and with greater accuracy. 
I wish to mention here that when Exstam in 1894 (p. 419) 
wrote in regard to me that I “in einer Menge von Fällen nur in 
Alkohol aufbewahrtes oder getrocknetes Material zu seiner [9: meiner] 
Verfügung gehabt’ as regards the investigations in flower-biology of 
Scandinavian plants, this is not quite correct, and I never made 
the above statement. On the contrary, both during my travels in 
West Greenland in 1884 when, on board a Danish man-of-war, I 
visited the Danish colonies situated between 64° and 69° N. lat. 
(Godthaab, Sukkertoppen, Holstensborg, Egedesminde, Jakobshavn 
and Godhavn) and also during my travels in Finmark, in 1885, 
where I stayed for a long time at Bosekop, Kaafjord and Tromsø 
(69° —70° N. lat.) I have always been very careful, above all things to
