of the forms and their occurrence in the field has shown, that 

 the last mentioned three are hereditary constant and hence 

 probably distinct species, the hitherto called .4. dioica var. 

 hyperborea from Greenland being in some details different 

 from all specimens seen by me of A. dioica from Europe or Asia. 

 Having, however, a very restricted access to literature and a still 

 lesser one to collections, I am at a loss to give full particulars 

 concerning the synonymy and distribution of some of the species, 

 and allow me to invite the attention of American botanists 

 to them, as most likely one or another of the species here con- 

 sidered as new may also occur in the eastern parts of arctic or 

 subarctic America. 



A more detailed study of the species together with full 

 diagnoses and figures will soon appear in the "Arbejder fra den 

 Danske Arktiske Station paa Disko."

 Species of Antennaria. 



1. Antennaria alpina (L.) Gaertn. 



West-Greenland: common to about Disco Bay, hence be- 

 coming scarcer and confined to well exposed lowland stations, 

 collected however at Cape York, 76° 07' and in Haves Sotmd, 

 on Grinnell Land, 79° 04'. 



East-Greenland: from the south to about 72°, common in 

 the better investigated places, but not found in North-East 

 Greenland. 



America: Arctic Archipelago up to Melville Island, 

 arctic, subarctic and alpine continental North America, Rocky 

 Mountains, xA.merican and Asiatic coasts of Behring Strait, 

 arctic and subarctic East-Siberia to Lena River, whence it 

 seems to be replaced by A. carpathica, Altai, reaching the coast 

 again in arctic Russia, Kolgujew, arctic and alpine North-Europe, 

 Iceland, wanting on Jan Mayen, Spitsbergen, Nova Zembla, 

 Franz Josef Land and New Siberian Islands; in other Avords, 

 an arctic alpine, nearly circumpolar species, however, not reach- 

 ing the northernmost limits for ])lant-gro\vth.
