The Flora of Disko Island and Adjacent Coast of West Greenland, 95 
A southern type; north of our area only once found at the south 
coast of Svartenhuk at ca. 71°42’ (P.), the northern limit in West 
Greenland. 
Abundantly flowering and fruiting. 
Hibernates covered by snow. 
oF 194. Potentilla (Comarum) palustris (L.) Scop. 
In smal, shallow pools. 
A decided southern type, only observed a few times in the southmost part 
of the area: Praestefjeld at Holsteinsborg 66°55’ (W. & H.; P. & E.); Sarfarssuag 
67°50’ (P. & E.). 
At the beginning of August our specimens from Holsteinsborg 
had even just become free from ice and would hardly be able to flower 
that year. But the specimens from N. Stromfjord were flowering abun- 
dantly, but we cannot say whether they were able to fructificate or 
not, and we did not find old fruits’. The plants were forming extensive 
patches totally filling the pool; in another pool just in the neighbour- 
hood Menyanthes, equally rare in Greenland, predominated. 
The specimens collected by us belonged to 7. typica Gunnarsson, 
subf. subglabra Gunnarsson: Bot. Nat. 1914 p. 218—219. 
The above mentioned places represent the northern limit of the 
species in Greenland; south of the area from various places right down 
to the southmost of Greenland, but everywhere rare. 
Hibernates under and in ice. 
A 195. Potentilla (Sibbaldiopsis) tridentata Sov. 
In sandy and poor heath and on rocks. 
Disko: Recorded from Godhavn (Lyngmarken) by R. Brown and Hart, 
but, according to Simmons, the specimens belong to Stbbaldia. Also by MEEHAN. 
In vain searched for by us during many years. Behind Skansen 69°25’ (P.) on 
tertiary sandstones. 
Mainland: Ata about 69°45’ (Th. P.!); from several places near Jakobshayn 
Icefjord (P.). Pakitsoq fjord 69°28’ in several places (Bg.; P.) From Jakobshavn 
icefjord southwards more frequent, but always far from the coast. In N. Stromfjord 
and south hereof common. 
A southern type. The above mentioned places represent the 
northern limit of the species. In South Greenland sometimes ascend- 
ing to 6—700 m. 
Flovers abundantly, but develops hardly any fruits in the northern 
parts of its range. 
Undoubtedly sometimes snowless during winter. 
1 In H. H. I have only seen unripe fruits on one specimen from the south- 
most Greenland,
