in manured soil. It seems as if Th. Wolf (1. c, p. 238) has supposed 

 something like this, but he gives it as related to var. macrophylla 

 Ser. (D. C, Prodrom. II, 571, 1825), which is nearer to the typical 

 P. niuea, than is Holböll's plant.

Note. Rather common around Danmarks Havn, but still more frequent 

 landward; it grows on gravelly slopes, snow-covered during winter.

Both low and hairy, and higher and less hairy forms were col- 

 lected, thus corresponding to f. typica and f. elatior Abromeit (Bibl.

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. с), and 

 in some localities the subf. argentea 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. К. Vet. Akad. 

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

 decision of the question. 



Loc. Hyde Fjord (var. intermedia); Cape St. Jacques; Ymers Nunatak; 

 Cape Marie Valdemar; Germania Land: Dove Bugt, Danmarks Havn, common; 

 St. Koldewey.

Note. It is one of the few species which flowers during the wliole 

 summer, more or less early according to its diiferent habitats. — The
