Vascular Plants of West Greenland. 373 



Polygoiiaceae. 



60. Oxyria digyiia (L.) Hill. — On moraine-slopes, river-banks, 

 in manured soil and damp spots on the heath; common. 



67. Polygonum vi vi pa rum L. — On heaths, rock-ledges well 

 covered with humus, in copses and on manured soil; common 

 everywhere. 



[Koenigia islandica L. has not been observed in the district in 

 question, but as it has been recorded from 72° 48' it has probably 

 been overlooked.] 



Cryophyllaceae. 



68. S a g i n a i n t e r m e d i a Fenzl. — hi open spots on the heath. 

 Ingnerit Fjord and Tartusaq; possibly overlooked in other places. 



69. Al sine ver na (L.) Wahl. — On clay, moraine material, on 

 rocky flats and in open spots on heaths and in bogs; very common 

 everywhere. Varies considerably; var. rubella (Wahl) is the most 

 common. 



70. Alsine biflora (L.) Wahl. — hi similar localities as the 

 above and as common, yaries especially as regards the length of 

 the floral shoots. 



71. Ammodenia peploides (L.) Rupr. var. diffusa Hörnern. — 

 On sandy shores: Lakse Fjord (72° 30'): not common; Amitsuarsuk; 

 hignerit Fjord; Tartusaq; Sarfarssuit and Igdlorssuit somewhat more 

 common. 



Northern limit, as previously known, 72° 4'. 



72. Arenaria с ilia ta L. var. humifusa (Wahl.) Hartm. — 

 Amitsuarsuk: in the bed of a mountain stream, and at Igdlorssuit 

 (S. Hansen). 



73. Stellaria longipes Goldie. — In the strand-vegetation, on 

 heaths, rocky flats, rocks and in copses; very common everywhere. 

 Varies considerably from plants quite low in growth and distinctly 

 glaucous to individuals 15 — 20 cm. in height, slender more grass- 

 green and small-flowered in copses under the willows. 



74. S t e 1 1 a r i a humifusa Rottb. — On clayey shores ; grows 

 undoubtedly everywhere if the conditions are favourable. 



75. Cerastium alpin urn L. — Occurs in almost all plant- 

 communities; very common everywhere. Here as elsewhere it varies 

 extremely among more or less low or erect and more or less hairy 

 or glandular forms. 



As especially characteristic of clayey and open moraine soil I 

 may mention a Cerastium which in nature difTers greatly from the 

 numerous forms of C. alpinum ; I have previously (Porsild, Hare 

 Island, p. 264) made a brief record of it. Especially distinctive is the
