THE FLORA OF SOUTH GREENLAND, 60°—62° N. LAT., 
ADDITIONS AND RANGE EXTENSIONS 
Woodsia ilvensis (L.) R. Br., common. 
Cystopteris fragilis (L.) BERNH., common. 
— montana (Lam.) Desv. (det. SELIM BIRGER). New to Greenland. 
This interesting and unexpected addition to the flora was found 
S. of Kiagtüt, growing in thickets on alluvial soil. The plant is 
generally considered a strict calciphile; the surrounding rocks 
are here sodalite- and nephelin-syenites and diabases. 
Besides in northern and central alpine Europe the plant 
occurs in North America, from Labrador to Alaska, but seems 
nowhere to be common. The nearest stations are S. Labrador in 
59° N., the St. Lawrence region of Quebec and one station on 
Newfoundland. 
Dryopteris Filix mas (L.) ScHoTT, quite common in thickets. 
— spinulosa (MüLL.) Kuntze var. americana (Fiscx). WEATHERB. 
(see FERNALD: Rhodora 1915, p. 144 and 1926, p. 146), common. 
According to information (in litt.) by our well-known fern-authority 
Dr. C. CHRISTENSEN of Copenhagen, all the Greenland material 
which has hitherto passed as Lastrea spinulosa 8 intermedia LANGE 
Consp. p. 187 belongs to this variety, the history of which is given 
by FErnALD l. c. Dr. CHRISTENSEN continues: 
The Icelandic specimens also belong here, only one specimen slightly 
approaches the European form, but the Faeröese are European. In Lapland 
both forms seem to occur and in Denmark we have the stout typical form 
with blackish scales in the woods, whereas in bogs, on Alnus-stumps, a smaller 
form with lighter coloured leaves and light scales occurs. To me they seem rather 
to be forms from sunny situations, and it is but natural to find such north of 
the wooded area... . (in litt.).
