The Flora of Disko Island and Adjacent Coast of West Greenland. 77 
A southern type without southern limit in Greenland; north 
of the area only twice observed: 70°28’ (Vh.) and 70°25’ (P.). 
Usually abundantly flowering, but during cold summers and in 
great lakes, in which the winter-ice does not thaw till far into the sum- 
mer, the flowering may fail to take place. Fructificates when flowering. 
’ {. terrestris. 
In moist soil among tall Carices, at the border of a little lake in 
Blwsedalen 69°17’ Disko, in which the above mentioned normal Green- 
landic forms occurs, a terrestrical form was observed with finely dis- 
sected leaves, sections linear, and rather rigid and considerably shorter 
than those of the normal form. Was just flowering Aug. 1913 (Th. P.!). 
1 148. Ranunculus divaricatus Scurank. New to Greenland! 
(Conf. Gerertr: Bot. Tidsskr. 19 p. 27 f. pygmaea). 
A rather deviating form was observed in a pond in the great valley 
from the head of Nordfjorden about 69°55’. The stalks and submerged 
leaves deep reddish brown, not fresh green-coloured as in the preceding. 
With numerous floating leaves, varying from 3—4 lobed 
with lobed sections, gradually to pluridivided with linear sections. The 
underside subpubescent. Submerging leaves capillary, not or only 
slightly collapsing when withdrawn from the water. 
With some hesitation | have classified this plant under the name 
given above, as the form of the leaves sheaths and the floral parts 
refer it to R. divaricatus, the flowers were somewhat larger and more 
showy than in the preceding. This variety was heretofore not recorded 
from Greenland neither from any aretic country. 
The plant was growing very vigorously. In some parts of the pond 
the surface of the water was quite covered by the floating-leaves and 
fair white flowers (Th. P. & P.). 
Both species hibernate under and enclosed in ice. 
T 149. Ranunculus affinis R. Br. Simmons: Ellesm. p. 101. 
ano 
Only once observed within the limits of the area at Arssalik, 67°30’ (Korwn.). 
Another time collected in S. Stromfjord a little south of our area (Jens.). These 
occurrences are quite isolated and outside the extension of the species. 
High-aretic type, otherwise known from North- and East Greenland. 
EL 150. Ranunculus acer L. 
In berb-mats and copses. 
Prestefjeldet at Holsteinborg 66°55’ (W. & HL).
