PREFACE. 
So far as flowering plants and ferns are concerned, the flora of the 
Falkland Islands may now be said to be thoroughly known. Ап account 
by Mr. C. H. Wright was published three years ago in the ‘Journal of the 
Linnean Society, his paper being the outcome of the study of extensive 
collections made by Mrs. Elinor Vallentin in 1898 and 1899 and presented 
to Kew a short time previously. With a view to making his account as 
complete as possible, Wright examined the older collections and incorporated 
previous records, and, by giving data as to localities and collectors, showed 
some of the changes which had taken place since the publication of the 
‘Flora Antarctica.’ Since the appearance of his paper, a memoir on the 
same subject has been published by Skottsberg, who, in addition, describes 
the vegetation from an ecological standpoint.
