The Flora of Disko Island and Adjacent Coast of West Greenland. 89 
Abundantly flowering and fruiting. 
Often snowless during winter. 
Vv 180. Lesquerella arctica (Wormsks.) WaArTson. 
On sand, especially in the domain of the carboniferous formations, 
on gravel, dry moraine and river-deltas. 
Disko: Coast of Waygat down to 69°50’ and Kuganguaq-valley, common (P.). 
Mainland: Nugssuaq peninsula: the coast of Waygat and the interior part 
of the great valley, common (P.); south of Torssukatak only found a few times: 
north of Ritenbenk (Sylow); Svarte Vogelbay (Htz.); Eqe 69°42’ (P.); Lerbugten 
about 69° (Bg.). 
A decided northern type; the mentioned places 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 imit 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 been 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 Ta. Hoxm records 
the plant from Proven 72°23’, Skarvefjeld and Asungasungaq near 
Godhavn. None of these specimens exist in H. H., and in vain I have 
searched for the plant in all the places through many years. — 
As a matter of fact 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 plants 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 Kangatsiaq 68°11’; we 
have only seen it south of this place (P. & E.). Isolated found at Akug- 
dlit 69°43’ (Engell) and at Jakobshayn 69°13’ (Sor.) (in vain searched 
for, P.); from several places in Sydostbugten and from Nuk at Chri- 
stianshaab 68°50’ recorded by the natives.
