Introduction. IARDEN. 
The plants mentioned in this list were mainly collected 
during the two Greenland Expeditions of Amdrup and during 
a third journey undertaken by me, in the years 1898—99, 1900 
and 1901—02. They were mostly collected and determined by 
myself. The plants found by Berlin and Nathorst during the 
short stay of ‘‘Den andra Dicksonska Expeditionen” in Kong 
Oscars Havn (Tasiusak) in 1883 are also entered in the list. 
They are published partly in the description of this expedition, 
partly in Kgl. Sv. Vetenskaps-Akademiens Handlingar og Bihang 
(see Literary List). I have also embodied the small collection 
brought home by Mr. Knutsen from the Danske Konebaads- 
Expedition in 1883—85 and published in Medd. om Gronl. III 
& IX together with the species found by Cand. Bay during 
the Expedition of Ryder in 1892 at Tasiusak and published 
by Mag. scient. N. Hartz in Medd. om Gronl. 
The limits of the district were traced from botanical and 
practical reasons. The northern limit is purely botanical and 
climatic, being distinctly expressed at Kap Wandel on abt. 66° 18’ 
lat. N. Here the coast becomes wider, the current that farther 
northward has kept the ice to the land now turns out, the 
inlets towards the south are broad and deep. The most nor- 
__thern points I have visited are at the inner end of the Sermilik 
inlet on about the same latitude, and I have therefore traced 
__the limit at the “Lille Isfjord” west of Kap Wandel on 66° 20' 
CYlat. N. The southern limit falls through the outer end of the
