Vascular Plants of West Greenland. 369 



The northern hmit, as previonsly known, was at 71° 47'. 



34. Ca rex glareosa Wahl. — Common where there are claj^ey 

 shores. 



35. Carex alp in a Sw. — Occurs, but not commonly, on rock- 

 ledges with a favourable aspect. Prøven (Hart), 72° 22'; Amitsuarsuk, 

 72° 23'; Ingnerik Fjord, 72° 3', 



The above localities are the northern limit of the species in 

 West Greenland. 



36. Carex rari flora (Wahl) Sm. — In moss-bogs and damp 

 heaths. 



While this species is extremely common around Disco Bay, here 

 it appears to be near its northern limit. Usually it occurred rather 

 sparsely and did not flower very abundantly; it was observed, how- 

 ever, in all the investigated localities. 



37. Carex aquatilis Wahl. var. stans (Drej.) Boott. — Along 

 lake-margins within Amitsuarsuk Qingua, on Svartenhuk, at Tartusaq 

 and Sarfarsuit and at Igdlorssuit. 



This species which is never absent from any of the lake-margins 

 near Disco Bay was noticeably rare here. 



38. Carex rigida Good. — On rocks, on heaths and in bogs; 

 common. 



var. В i gel о vi i (Torr.) Boott. — In bogs and along lake-margins, 

 and sometimes along streams or in damp places in copses; common. 



39. Carex scirpoidea Michx. — On rock-ledges, on luxuriant 

 heaths and the margin of copses. Lakse Fjord Qingua; Amitsuarsuk: 

 common in the lowland; Ingnerit Fjord: common; Tartusaq and 

 Igdlorssuit; rare. 



40. Carex rupestris All. — Common on dry rock-ledges. 



41. Carex supin a Wahl. — x\mitsuarsuk Qingua and Sarfars- 

 suit; rare. 



42. Carex pedata Wahl. — Lakse Fjord, Amitsuarsuk and Igd- 

 lorssuit; not common. 



43. Carex raisandra R. Br. — Very common on heaths and 

 on rock-ledges well covered with humus; at the head of the fjords 

 as much as 35 cm. high. 



44. Carex ustulata Wahl. — This rare species which has 

 hitherto been found onh^ a very few times in the Arctic-American 

 region ^ (cf. Simmons, Vas. PI. Ellesm., p. 139) was eagerly searched 

 for everywhere. Only at Igdlorssuit, 71° 14', did we succeed in finding 

 a single tuft, which grew on a fairly dry heath near the sea. In 

 addition it was found by Hart at Prøven, according to Simmons, 

 "Rare or Dubious PI.," etc. 



') I found it also at Maqaq on Nugsuaq.
