The Flora of Disko Island and Adjacent Coast of West Greenland. 139 
A 244. Pleurogyne rotata (L.) Gnrisen. 
On sandy clay near the shore as well on raised marine clays. 
Mainland: Christianshaab 68°47' (Rink); Egedesminde 68°45’ (Rink); Tasi- 
ussarssuaq, 65°25' (Bg.); Nordre Stromfjord at Ipiutarssuag, 67°42" (P. & E.) and 
another place (Korn.); Itivneq, 66°55’ (P. & E.); Ikertéq fjord, 66°45’ (V.). 
A southern type, south 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. 
ip 245. Menyanthes trifoliata L. 
In small lakes. 
Mainland: at Tasiussarssuaq, 68°25’ (Bg. BL); Nordre Stromfjord, on the 
portage at Sarfarssuaq 67°50" (Korn. P. & E.); Ikertéq fjord, 66°45’ (V.). 
A distinet 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 plants 
are covered by or enclosed in ice. 
XL. Borraginaceae. 
246. Mertensia maritima (L.) Gray. 
On sandy sea shore, hence sometimes in manured soil at some di- 
stance from the shore. 
Disko and Hare © very common (P.). 
Mainland: Common in the basaltic and sand stone districts, searce in the 
gneissic, because suitable localities are restricted and local. Also observed in Nordre 
Stromfjord, at the mouth as well as at the head (P. & E.). 
Its range in Greenland is rather remarkable and resembles that of 
the northern types, although the plant on both sides of the Atlantic 
oceurs 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
