394 THE FLOWERING PLANTS OF NOVAYA ZEMLYA, ETC. 



6. E. suLPHUREus Sol. As a rule this is a finer and more 

 showy plant than R. nivalis. There are specimens from Cape 

 Matiusela seven inches in height, with blossoms over an inch in 

 diameter. The range and distribution of this species coincides 

 with that of H. nivalis. Dolgoi Island ; south shores of Waigats ; 

 Cape Matiusela ; DolgaBay; Neckwatowa ; Nameless Bay ; Gubina 

 Bay ; Goose Land ; Beluga Bay, Lutke Land ; Pachtussow Islands ; 

 Ziwolka Fiord. 



7. R. ACRis L. f, BOREALis Trautv. The commonest buttercup 

 throughout the regions visited. Extending from the sea-shore to 

 altitudes of two hundred feet and more. This is a most variable 

 plant, and without the connecting links it would puzzle the ordinary 

 observer to decide that the extremes belong to the same species. 

 There are in the collection specimens from Waigats, and Lutke 

 Land as well, with stalks over eight inches in length, and blossoms 

 an inch and a quarter in diameter ; and from the same localities 

 specimens with stalks of not more than half an inch, and blossoms 

 three-quarters of an inch in diameter. Habarova ; south shores of 

 Waigats ; Cape Matiusela ; Dolga Bay ; Islands Kostin Shar ; 

 Neckwatowa ; Goose Land ; Nameless Bay ; Gubina Bay ; Silver 

 Bay ; Beluga Bay, Lutke Land. 



8. R. AURicoMus L. Found at Cape Voronoff, 2nd of July, 

 1897, where it grew in beds on sandy hillocks close to the sea-shore. 

 It was not uncommon around Beluga Bay, Lutke Land, reaching 

 an altitude of one hundred feet. It does not appear in the collec- 

 tions from any of the other stations. It is just possible that 

 this may be the R. affinis recorded by other botanists from 

 Novaya Zemlya, but after a careful comparison with specimens of 

 Pi. affinis from many quarters, including Robert Brown's type in the 

 herbarium of the British Museum (Natural History), I cannot assign 

 these plants to anything but true H. auricomiis L. Mr. Burkill 

 attached the following note to the specimens of this plant submitted 

 to him : — " R. affinis R. Br., a North American plant — perhaps a 

 confusion of two or three forms specifically distinct — is in its arctic 

 type difficult to distinguish from R. auricomus L. Types of the 

 original plant so named by Robert Brown exist at Kew and at the 

 British Museum, and may be, as Lange points out, distinguished 

 from Pi. auricomus by the longer head of fruit. To R. auricomus I refer 

 the plant from Waigats collected on the Nordenskiold Expedition, 

 and named R. affinis, a specimen of which exists at Kew. Fellmann 

 (PlantcB ArcticcB, no. 5) has distributed a very similar plant from 

 Eastern Lapland. You were fortunate or careful enough to collect 

 the round head of fruits, which is that of R. auricomus, and not of 

 R. affinis. The latter therefore is apparently to be removed from 

 the Novaya Zemlya list (Waigats zone), and to be replaced by R. 

 auricomus.'' 



9. Caltha palustris L. An extremely common plant through- 

 out the regions visited, growing round lakes and meres, in bogs, and 

 by the banks of rivulets. It shows great variations according to 

 locality. In favoured spots the plants are as large, and with as fine
