The species of Flowering Plants and Perns in the Flora of 
the Arctic American Archipelago, and their distribution 
within that region. 
In the following pages I ha ve compiled a complete list, as far as possible, of 
every record of occurrence within the area of research of each separate species. 
The special locahty for which the plant is stated or whence I have seen specimens 
is indicated as accurately as I have been able to do, hut in many cases the sources 
are very incomplete, for instance when only the name of a large island occurs in 
the label, or when in a Hst or collection plants from different places are thrown 
together indiscriminately and only the collector or the expedition that brought them 
home is indicated. Only in one instance I have not deemed it necessary to go so 
far into detail, viz., when Ellesmere Land is concerned. As all information about 
that region up to 1906 is brought together in my Flora EUesm., it may be enough 
to reter to it for further particulars about the dispersion of common species, in 
stead of reprinting the whole Hst of locahties here. Only the rare species, found 
in one or a few sporadic locahties, or such about which interesting records have 
appeared låter, have been treated in detail. In all other cases I have condensed 
the information given in my paper and only added the names of the different re- 
corders. 
For all other parts of the Archipelago every separate locality is entered, as 
far as I have had any opportunity to look up specimens or records. Where speci- 
mens have been inspected, the herbarium they belong to is indicated by letters in 
brackets, viz.: British Museum of Natural History (NHM), herbarium of the Royal 
Gardens, Kew (KH). herbarium of the State Museum oi Stockholm (SH). herbarium 
of the Botanical Garden of Copenhagen (CH), collections of the Linnean Society of 
London (LS). In rather many cases. however, no specimens were to be found to 
bear out a statement in a list from a certain expedition. In such cases I have 
entered a reference to the work where the records occur, the name of the book or 
paper being abridged as indicated in the bibliography at the end. Where a record 
has seemed doubtful, I have discussed it and stated my reasons for accepting or 
excluding it. Doubtful species have got no number and ihe treatnient of is
