The Flora ol' Disko Island and AdjaccnL (>oasl of West Greenland. 8{) 



Abundanth flowering and fruiting. 

 Often snowless diiring ^^^nter. 



V 180. Lesquerella arctica (VVormsk.t.) Watson. 



On sand. especially in the domain ol' the carboniferous formations, 

 on gravel, dry moraine and river-deltas. 



Disko: C^oast ol' Waygat down to 69°50' and Kiigånguaq-valley, common (P.). 



Mainland: Niigssuaq peninsula: the coast of Waygat and the interior part 

 of the great valley, common (P.); south of Torssukåtak only found a few times: 

 north of Ritenhenk (Sylow) ; Svarte Vogelbay (Htz.); Eqe 69°42' (P.); Lerbugten 

 about r,y° (Bg.). 



A decided northern type; the mentioned piaces represent the 

 south limit in West Greenland. 



Abundantly flowering and fruiting. 



Perhaps snowless now and then during winter. 



XXIII. Crassulaceae. 

 A 181. Rhodiola rosea L. 



On sunny rocks especially near the shore, on sand and gravel; 

 also to be found inland far from the sea. 



It is very difficult to account for the distribution of this species 

 here at the north limit because of some records, which seem to have 

 appeared through a slip of the memory or changing of labels. An old 

 record by Kane exist from Upernivik; the species has not be'en re- 

 found here, but as Kane's plant-lists contain many mistakes, evidently 

 owing to confusion of material from North- and South Greenland, we 

 need not pay any attention to this record. Later on Tii. Holm records 

 the plant from Prøven 72°23', Skarvefjæld and Asungasungåq near 

 Godhavn. None of these specimens exist in H. H., and in vain I have 

 searched foi' the plant in all the piaces through many years. — 



As a matter of faet the natives do not know the plant from God- 

 havn, and as Rhodiola is a highly valued article of food it certainly 

 belongs to the piants known by the natives. 



On the mainland common from Holsteinsborg to the southern 

 part of the district of Egedesminde. 



"Kruuse states the northern limit here at Kangåtsiaq 68°11'; we 

 have only seen it south of this place (P. & E.). Isolated found at Akug- 

 dlit 69°43' (Engell) and at Jakobshavn 69°13' (Sor.) (in vain searched 

 for, P.); from several piaces in Sydostbugten and from Nuk at Chri- 

 stianshaab GS^'dO' recorded by the natives.
