INTRODUCTION. 
The Gjöa Expedition under Captain Roatp Amunpsen has brought home 
a rather large collection of dried plants collected 1) at Gjéa Harbour, 
King William Land, and 2) at King Point and Herschell Island 
near the shore of the Beaufort Sea, a little to the west of the delta of the 
Mackenzie River, Canadian part of Alaska l. Most of the plants were collected 
by the steward Mr. A. H. Linpstr6m, and a small collection was made by Mr. 
GoprreD Hansen of the Royal Danish Navy, the second officer of the expe- 
dition. Neither of the collectors having any botanical training, the plants do 
not give any complete idea of the floras of the countries in question; never- 
theless the large material of well-chosen plants Mr. Linpstr6m especially has 
brought together is quite excellent. I think we may go so far as to say 
that all the more conspicuous flowering herbs which were in full development 
at the time of the stay of the expedition, have been taken, and a good many 
of species are represented by numerous specimens. The shortcoming of the 
collection is mainly the scarceness of grasses and grass-like plants. To a 
certain extent this gap has been reduced by a careful examination of the tufts 
of the larger plants and mosses, during which I have detected fragments of 
many grass-like monocotyledons. I think therefore that the list from King 
William Land is rather representative, but on the other hand that from King 
Point and Herschell Island is far from being so, the flora of this region being 
much richer. 
The collection of Mr. Linpstr6m belongs to the University of Christiania, 
and I owe to the kindness of Professor Dr. N. Wire, Director of the Botanical 
Garden and Museum, Christiania, the permission to work it out; the small 
collection made by Lieutenant GopFRED Hansen has been presented to the 
Botanical Museum of the University of Copenhagen by the collector himself. 
The first duplicate set of the collections are given to the Museums of Copen- 
hagen and Christiania respectively. — I take this opportunity to offer my 
sincere thanks to my friend Professor Witte for his placing the material at 
my disposal and for his trouble with the arrangement of the printing of this 
paper. 
UA single species Ammodenia peploides (L.) Rupr. var. diffusa Hornem., was gathered 
on Douglas Island on the south coast of Victoria Land (Aug. 2oth, 190531.
