In arranging the plants I have followed Lange’s ‘‘Con- 
spectus Flora Groenlandica” (Meddelelser om Grönland II) by 
reason of the comparison with this fundamental work though 
it has become antiquated in several respects (f. inst. the main- 
tenance of Apetalae as a special group). I have also followed the 
nomenclature ofLange as far as possible, and I have innovated 
only where newer works have necessitated my doing so. These 
innovations are greatest within the family Cruciferae where I 
have followed Gelert’s revision for the genera Draba and 
Cochlearia, ‚Compositae, determined by Amanuensis Dahlstedt 
in Stockholm, Cyperaceae, determined by Inspector of the Bo- 
tanical Museum at Copenhagen, C. H. Ostenfeld, the other 
orders of Monocotyledones and Fülices, where the limitation of the 
species stated in ‘‘Flora Arctica” has been followed. In several cases 
especially when determining the large genera I have not been 
content with the result obtained, but I have been obliged to stop 
at what I considered a preliminary position, as the systematising 
cannot be final, until the plants have been cultivated and ob- 
served continually through years in the arctic countries. There 
is now every prospect of this going to be done at the new 
established Danske Arktiske Station in Disco, and it is my 
hope that also systematic questions will be treated there. 
In composing this list I have besides those cited in Lange’s 
Conspectus p. XVI ff. employed the following works:
