On the Genus Antennaria in Greenland. 277 



on the assumption, that the plant, which Don designates hyperborea, 

 originates from Europe; this however I am not in position to verify ^). 



I have had no opportunity of studying A . groenlandica growing, so 

 my opinion of it is based on the material belonging to the Botanical 

 Museum at Copenhagen. It is certainly closely related to A. dioeca, but 

 differs in the following 2). 



A. groenlandica is apogamous, male plants never having been found 

 in Greenland although it seems to develop good fruits. Juel states, as 

 regards A. dioeca, that it is, at least in Scandinavia, fertilized normally. 



A. groenlandica is smaller in all its vegetative parts, than is the case 

 with the European and Asiatic specimens of A. dioeca; the leaves espe- 

 cially are narrower even than those found on the forms of A. dioeca in 

 the high mountain districts. 



Hairiness: While A. dioeca varies somewhat as regards this character. 



^ In case the matter should be studied more closely by help of the older 

 literature, to which the author has had no access, I have looked into some of 

 his quotations, to avoid the names given by him to his Antennaria species being 

 liable to alterations. It is correct, that A. hyperborea originally came from Europe. 

 As far as I can ascertain, it was mentioned for the first time under the name of 

 Gnaphalium hyperboreum by J. Donn in his "Hort. Cantabr.", of which I have 

 only had access to ed. 7 (1812). The name is a nomen nudum, but the plant is 

 described and pictured by D. Don in English Botany, Suppl. tab. 2640 (1831), 

 who quotes just the above mentioned ed. 7 of Hort. Cantabr. and no earlier 

 edition. Don says, he is convinced, after having had it under culture, that it 

 is an independent species, and not a form of A. dioeca. It came from the Scotch 

 mountains, and it seems to me an open question, if the form occurring in the 

 Alps, which goes under the name of A. dioeca var. hyperborea (Don), is identical 

 with the form of the Scotch mountains, and of which latter Porsild has had 

 no specimen for comparison. His A. groenlandica is however undoubtedly different 

 from both the European forms. C. H. Ostenfeld. 



2 For this comparison (see Figs. la. 2b, 6) I have been able to examine 

 the following specimens of A. dioeca and its variety "hyperborea", mainly ob- 

 tained from the Botanical Museum at Copenhagen :
