yV 244. Pleurogyne rotata (L.) Griseb. 



On sandy elay near the shore as well on raised marine clays, 



Mainland: Chrlstianshaab 68°47' (Rink); Egedesminde 68°45' (Rink); Tasi- 

 ussarssuaq, 68°25' (Bg.); Nordre Strømfjord at Ipiutarssuaq, 67°42' (P. &- E.) and 

 another place (Korn.); Itivneq, 66°55' (P. & E.); Ikertoq fjord, 66°45' (V.). 



A Southern type, soiith of the area found several times and 

 becoming common between 60 — 61° (Ros.). The above mentioned loca- 

 lities are the northern limit. 



Abundantly flowering and fructificating. In the localities seen by 

 us it formed rather extended patches. 



The habitats are covered by snow during winter. 



J. 245. Menyanthes trifoliata T. 



In small lakes. 



Mainland: at Tasiussarssiiaq, 68°25' (Bg. BL); Nordre Strømfjord, on the 

 portage at Sarfarssuaq 67°50' (Korn. P. & E.); Ikertoq fjord, 66°45' (V.). 



A distinct southern type. South of our area found several 

 times, but always locally. 



Our specimens were partially deflowered August 6. 1918, an un- 

 favourably year. Ripe or wintered fruits were not observed. Rosen- 

 vinge reports only of unripe fruits from the southmost Greenland and 

 in the H. H. all specimens from Greenland are without fruits, whereas 

 the plant fructificates in Iceland. 



During winter the lakes will freeze to the bottom and the piants 

 are covered by or enclosed in ice. 



XL. Borraginaceae. 



I 246. Mertensia maritima (L.) Gra.y. 



On sandy sea shore, hence sometimes in manured soil at some di- 

 stance from the shore. 



Disko and Hare O very common (P.). 



Mainland: Common in the basaltic and sand stone districts, scarce in the 

 gneissic, because suitable localities are restricted and local. Also observed in Nordre 

 Strømfjord, at the mouth as well as at the head (P. iS: E.). 



Its range in Greenland is rather remarkable and resembles that of 

 the northern types, although the plant on both sides of the Atlantic 

 occurs down to the shores of temperate regions. South of our area it 

 is known in West Greenland only from two spots, viz. at 65°20' and 63° 

 and in the whole of East Greenland it was only found in 3 specimens 

 near the settlement of Angmagssalik 65°37' (K.) perhaps here as an
