Vascular Plants of West Greenland. 371 



Northern limit, as previously known, TO"" 30'. 



49. S с i r p u s с æ s p i t о s u s L. — Formed the bulk of the vege- 

 tation along the margin of a small lake at the head of Lakse Fjord, 

 72" 27'; flowered abundantly. 



Northern limit, as previously known, 70° 8'. 



50 E г i о p h о r u m S с h e n с h z e г i Hoppe. — Found in wet bogs 

 and along lake-margins; fairly common at Tartusaq, Sarfarssuit and 

 Igdlorssuit; it also occurred at the other investigated localities, but 

 apparently very sparingly; it might, however, have been overlooked 

 owing to absence of flowering stems. 



51 . E r i о p h о r u m p о 1 y s t a с h y u m L. — In wet bogs and along 

 lake-margins; very common everywhere, but often sterile. 



Juncaceae. 



52. June us arc tiens Willd. — In a wet bog at Igdlorssuit, 

 71° 14'. 



Northern limit, as previously known, 70° 40'. 



53. J une us castaneus Sw. — In wet bogs and along lake- 

 margins. Amitsuarsuk, 72° 23', in the lowlands; Ingnerit Fjord; 

 Tartusaq; Sarfarssuit; Schade's Islands and Igdlorssuit. In the last 

 place it was легу common; in all the others it occurred rather spa- 

 ringly and was confined to protected localities. 



Northern limit, as previously known, 70° 45'. 



54. JuncusbiglumisL. — On heaths, in bogs and wet spots 

 on rock}' flats; common everywhere. 



55. Juncus triglumis L. — ^ In similar localities as the above, 

 no doubt often overlooked, but hardly as common as the аЬоле. 



56. L u z u 1 a m u 1 1 i f 1 о r a (Ehrh.) Lej . — On luxuriant heaths 

 and on rock-ledges well covered with humus in the interior of Lakse 

 Fjord (Orpik), 72° 30'; Amitsuarsuk, and Ingnerit Fjord; at Tartusaq; 

 Sarfarssuit and Igdlorssuit. 



As Simmons (1. c.) has cancelled all previous records from N. W. 

 Greenland as erroneous, this must, for the present, be regarded as 

 the northern limit of the species. 



57. Luzula nivalis (Laest.) Beurl. — Common everywhere on 

 heaths and rocky flats. 



58. Luzula con fusa Lindeb. ^ On heaths and rocky flats, in 

 bogs which are not too wet and on rocks; common everywhere. 



59. Luzula spicata (L.) DC. — In fertile and protected locali- 

 ties, on rock-ledges covered with humus, on old heaths and along 

 the margin of copses. Amitsuarsuk (72° 23') and probably several 

 other places.
