POSTSCRIPT 
\ X YHEN in 1920 the Committee for the geological and geographical 
investigations of Greenland kindly undertook to publish the pre- 
sent work and immediately put the first part to press I hoped to be able 
to finish the second part during the printing of the first part. In this, how- 
ever, I was hindered by various other works of official character, travels 
abroad etc., and later on both I and my collaborator have had 
occasion to make further observations in hitherto unexplored parts of 
the area whereby the preliminary work accomplished for the second 
part had to be revised. This second part will contain a survey of the 
distribution of the species and types of plants within the area as far 
as possible with due allowance to the geographical, geological and 
climatological conditions. 
My reason for letting the first part appear before finishing the 
second is due to the purely practical demand that the present volume 
in "Meddelelser om Grønland” has to be concluded. In this connection 
I must express my sincerest thanks to the Committee for the unique 
patience shown at this delay.
