mons has pointed out, all the records from N.W. Greenland and 

 Ellesmereland are undoubtedly wrong, and Rowlee and Wiegand's 

 record from 74° 15' must therefore be regarded as the northern limit 

 of the species — that is if their specimen has been determined correctly 

 and it is not in reality one of the numerous forms ofthe preceding species. 



23. Glyceria Va hi i an a (Liebm.) Th. Fr. — Tartusaq: on 

 exposed gravelly heaths; rare. 



24. Glyceria vil foi de a (Anders.) Th. Fries. — It is scarcely 

 ever wanting on clayey shores in places where the locality is favour- 

 able to its occurrence; but as such localities are rare it does not 

 play any important rôle in the vegetation. 



25. Glyceria d i stans (L.) Wahl. — No doubt common on 

 clayey and sandy shores and in manured soil. 



26. Glyceriaaugustata (R.Br.) Fr. — Found on clayey slopes 

 and sea-margins at hignerit Fjord, Tartusaq and Igdlorssuit, 



27. Glyceria tenella Lange. — To this species I refer with 

 some doubt a small Glyceria from the southern side of Ingnerit Fjord. 

 The narrow panicle, the short stem, the slightly developed ligule and 

 the highly prominent veins on its pales agree with this species, but 

 in habit the specimen recalls certain forms of Gl. maritima. 



28. Festuca о vi na L. — Found commonly everywhere on 

 rocks, on dry heaths, rocky flats and sandy shores. 



29. Festuca rubra L. var. arenaria Osb. — hignerit Fjord, 

 72° 3': a single tuft; Tartusaq, 71° 25': rare; Igdlorssuit: fairly common 

 everywhere in the sand near the shore. 



The northern limit, as previously known, was 70° 40'. 



30. Ely m us a r e n a r i u s L. var. v i 1 1 о s u s E. Mey . — Common 

 at Igdlorssuit. North of this locality it was only seen at Manitsoqut 

 on the peninsula of Svartenhuk, 71° 29'. 



Northern limit, as previously known, 70° 47'. 



Cyperaceae. 



31. Car ex nardina Fr. — Common everywhere on rocks, on 

 dry heaths and rocky flats. At the head of Lakse Fjord specimens 

 were found, as much as 30 cm. in height, which recalled C. capitata Sol. 



32. Car ex incurva Lightf. — Occurred very sparsely on dry 

 clayey sea-margins at Tartusaq. 



[Carex ursina has been found north and south of our district 

 and has perhaps been overlooked by us.] 



33., Carex lagopina Wahl. — At the heads of fjords on 

 luxuriant heaths and on rock-ledges well covered with humus; not 

 rare as far north as 72° 30', but only in the lowlands. Occurred in 

 addition at Orpik, Ingnerit, Tartusaq, Sarfarssuit and Igdlorssuit.
