Spil>hergen: but their appearance in Europe makes it doubtful how they 

 >hi.uld lie reckoned in Greenland, especially as they are not found in 

 Ellesmereland, nor in the far north of Greenland. The safest way will 

 be to reckon them alternatively to Group A. and Group D. 



Five of the species in Group VI, 2: Potentilla metadata, Koeni(/i<t 

 ixlamlica. Carex salhia, C. layopina, and Calamagrostis arnudina- 

 cea, entering our special area only in N. E. Greenland, may doubtless 

 he put in Group S, as may also Draba crassifolia, which just reaches 

 Cape Hold with Hope; perhaps also Sayina uicaUs, which, however, 

 i- a plant easily overlooked or confounded whith others, and may. there- 

 fore, prohahly be of wider range than is as yet known. Pedicularis 

 /Iftninirti (Gr. VI, 3) I think hest to leave in Group D. It might also 

 be put in Group A, as being most spread in America; but it is not 

 known from any part of the Archipelago, and has certainly come to 

 N. W. Greenland from the south of Melville Bay. On the other hand, 

 it is known from Iceland and the northernmost parts of Europe, and I 

 think it may still be discovered in Siberia also. 



The species of Group VI, 4, have doubtless reached N. W. Green- 

 land by way of Danish Greenland, One of them Ardbis Hooker i, is 

 found on the arctic shore of America and consequently goes into Group A: 

 the three other.-. Mcrfensia marifinia, Vdcciniunt Vitis idaea, and Dralxi 

 hiraitd, are more or less circumpolar and ubiquitous species, which may 

 go tu Group S. The 3 species in Group VI, 5, Carex pedata, C. mpe- 

 .s'/r/x. and Kobrcsia bipartita, by their appearance in the most ameri- 

 can part of Ellesmereland, make it impossible to doubt that they exi-t 

 also in other parts of Arctic America, where they may have been 

 overlooked. If we presume their existence there, they may be put in 

 Group U. 



Aira flexuosa (Gr, VI, 6) is decidedly a southern plant; its single 

 locality in N. W. Greenland is doubtless an outpost from its Danish 

 Greenland area, but how it has reached Ellesmereland is doubtful. 1 

 think it hest to place it in Group D. Still more difficult is it to form 

 an opinion as to the way by which Ayropifnitn violaccum (Gr. VI. 7) 

 ha- reached Grinnell Land, as it i.-, not known from any locality in Arctic 

 America, either in the continent or in the islands: and there is an enter- 

 vening, space of more than 10 down to its northern limit in Greenland. 

 I place it in Group D. 



La-tlv we have Sd.rifrdf/d Jlirculnx (Gr. VI. S), which in Elles- 

 mereland is doubtless an american plant, but has, perhaps, reached 

 N. E. Greenland in the -anie way as have the species of Group E.
