Where in this paper a locality is given without collector-name, 

 the collector is either F. Børgesen or H. Jonsson. The first has 

 collected most of the Færoese, the latter several Færoese (in winter 

 time) and Icelandic specimens. Most of the original specimens 

 belong to the Botanical Museum of Copenhagen.
