As this species is rather common, or at least widely spread in the 

 northern parts of Danish Greenland, it would seem probable that it 

 should also grow in the region to the north-west. Indeed it is recorded 

 by almost every traveller who has visited our area, yet notwithstanding, 

 I have no doubt about my right to cancel most of their statements. 

 As I have discussed in my Fl. Ellesm. and above, most of them are 

 quite useless on account of the confusion of different species. HART 

 (1. c.), for instance, notes it as "common everywhere", but all his speci- 

 mens in the London collections belong to other species, DURAND has 

 certainly used the name in a wrong sense both in PI. Kan. and in Enum. 

 pi. Smith S., and as far as I can see, there is only the record of WETH- 

 ERILL from Whale Sound which is most probably right, which may be 

 used. For my part I have only found it within a small area in Foulke 

 Fjord. P. nivea also after the removal of the falsely included species, 

 such as P. Vahliana, P. rubricaulis, and others, is yet a rather vari- 

 able plant. Even at the Foulke Fjord locality three forms of it can be 

 distinguished. The rarest of them is the form with rather broad, rounded 

 leaflets, having short teeth (205, 4270), as the plant generally appears 

 in Europe. Somewhat less sparingly found was the form that is the 

 most common in the arctic regions, especially in Greenland, which has 

 longer and narrower leaflets that are more deeply incised (1460). This 

 form corresponds to the variety d pinnatifida of LEHMANN, whose i 

 ppntaphylla again includes the most luxuriant forms with 5-digitate 

 leaves occurring in greater abundance. However, none of my specimens 

 can be referred to the latter. But in another respect they are somewhat 

 different. Some of them show the typical dense white woolly clothing 

 of the lower surface of the leaflets, but others are almost entirely quite 

 green (or reddish). They do not, however, quite agree with the E sub- 

 viridis of LEHMANN, nor are they referable to var. pallidior, SWARTZ, 

 Sum. Veg. Scand. The plant in this slate indeed shows a rather close 

 resemblance to the P. Hookeriana, LEHM., such as it is figured in Rev. 

 Potent., T. 55, but that species of which specimens are entirely lacking 

 in all collections to which I have had access, is said to have the leaves 

 white-tomentose on both sides. Such specimens are distributed under
