54 H. G. SIMMONS. [sec. arct. exp. fram 



Harbour (1085, 1880). South coast: Fram Fjord (1630, 1660); Harbour 

 Fjord, "green patch" near the anchorage (2151), Seagull Rock (2599, 

 2650); Goose Fjord, Falkon Cliff (2882, 3771), Gallows Point. 



Distribution: Northeastern and Northwestern Greenland (cf. 

 above), Arctic American Archipelago (only a few specimens seen at Kew, 

 but probably spread all over the islands), Arctic America, in the conti- 

 nent down in the temperate parts and Rocky Mountains to Alberta, 

 Wyoming and Colorado. 



Potentilla anserina, L. 



This species is recorded by Hart, Bot. Br. Pol. Exp., from Cape 

 Sabine (Bedford Pim Island), but there are no specimens in the Nat. 

 Hist. Museums or at Kew, to confirm his statement. He has also 

 recorded it from Foulke Fjord and from Proven in Greenland. Now it 

 is lacking in the hst of the plants from the Hayes expedition, which 

 wintered at Port Foulke, and, in the Danish part of the coast no other 

 collector has found it north of the Disco-district, and therefore I think 

 one is well justified in excluding it from the Ellesmereland flora. What 

 Hart can have taken for P. anserina is not easily decided, but most 

 probably, it must have been one of the preceding species. 



Potentilla nivea, L. 



This species is recorded by Hart, Bot. Br. Pol. Exp., from all his 

 locaUties from Danish Greenland up to the north coast of Ellesmere- 

 land as well as by Greely, Rep. Indeed it is not to be denied, that 

 it could perhaps grow there, as it is to be found in Greenland, at least 

 as far north as Foulke Fjord, and it seems also to be spread in the 

 Arctic Archipelago. There are, however, no specimens to be found that 

 would give the necessary confirmation to the statement of Hart, which 

 is the more unreliable, as he has thrown together both P. Vahliana, 

 Lehm. and P. pulchella, R. Be. with it, which shows, that he has had 

 very little knowledge of these species (cf. under P. pulchella and P. 

 rubricaulis). In all probability. Hart has taken P. rubricaulis for P. 

 nivea, even if there are no specimens of the former from Ellesmere- 

 land in the London collections, but still it may be possible that Greely, 

 who has recorded P. nivea as well as the var. subquinata, has also 

 had specimens of the true P. nivea in his collection. At all events, 

 all the localities from Hayes Sound and adjacent parts in Hart's hst 

 are to be excluded.
