The mode of occurrence of this species here seems to indicate 

 that it is here near to its northern hmit. It is recorded from Uper- 

 navik by Vahl, but has not since been found again; Vanhøffen 

 did not find it to be common around Umanag. Nathorst and Sim- 

 mons did not find it in N. W, Greenland, and Greely and Hart's 

 records from Grinnell-Land require verification (cf. Simmons, Vase. 

 PI. Ellesm., p. 181). On the other hand, in N. E. Greenland it is 

 known to occur right up to 77° N. lat. (Ostenfeld & Lundager, p. 7). 



Lycopodiaceae. 



7. Lycopodium Selago L f. appressa Desv. Observed 

 everywhere on luxuriant heaths and on rock-ledges well covered 

 with humus; on level country exposed to the wind it may often long 

 be searched for in vain. 



8. Lycopodium anno tin um Lf. pungens Desv. In similar 

 localities as the above; was observed at Lakse Fjord (Orpik), Amit- 

 suarsuk, Ingnerik Fjord and Igdlorssuit; plants everywhere few in 

 number, but in fruit. 



Recorded by Vahl from as far north as Upernavik, 72° 48". 



Gramineae. 



9. Hie roch loë alpina (Liljebl.) Roem. & Schult. On heaths 

 and on sunny rocks well covered with humus, also on the margin 

 of willow copses; not rare; has been searched for in vain on 3'oung 

 morainic soil. 



At the head of the fjords it was one of the most conspicuous 

 grasses of the heaths. There it became very vigorous, as much as 

 60 cm. high. 



10. Alopecurus alp in us Sm. Very common. It occurs — 

 as it does elsewhere in Greenland — in uninhabited places as deli- 

 cate, scattered individuals ; but near inhabited or previously inhabited 

 places it forms large, dense tufts. 



11. Agrostis borealis Hartm. On sunny, fairly dry rock- 

 ledges at the head of Lakse Fjord, 72° 30', and Amitsuarsuk, 72° 23'. 



In West Greenland the hitherto-known northern limit of the 

 species was 72° 25' (Vanhøffen). 



12. Ca la magr о st is arundi nacea (L) Roth. var. purpuras- 

 cens (R. Br.). In fairly dry and sunny places at the head of the 

 fjords, as far north as 72° 30'; not rare. Igdlorssuit: rare. It appears 

 to grow by preference on sandy and gravelly substrata and is there- 

 fore frequently found in carboniferous sandstone areas, but often at 

 a great distance from the coast.
