Among the plants brought home by the Danmark Expedition 

 I did not find any belonging to the typical D. integrifolia M. Vahl. 

 The whole material from Germania Land is true D. octopetala L. in 

 its small-leaved high-arctic form: f. minor Hook. (Transact. Linn. 

 Soc, 14, 1825, p. 387); some specimens are hairy on the upper side of 

 the leaves and may be referred to subf. hirsuta N. Hartz (1. c), and 

 in some localities the subf. argren/ea A. Blytt (Norges Flora, vol.3, 1876, 

 p. 1176), with leaves silver-white lanate on the upper side was observed. 



The fragmentary specimens collected by Captain Koch on Peary 

 Land (Hyde Fjord) stand between D. octopetala and D. integrifolia 

 and may be D. octopetala, var. intermedia Nathorst (Öfv. K. Vet. Akad. 

 Förh. 1884, No. 1, p. 24j, but the material is too scanty for definite 

 decision of the question.
