24 Monten P. Porsivp. 
Ascending at least to 700 m.

protected by the withered old leaves. 
Abundantly fruiting. 
A 3. Dryopteris dilatata (Horrm.) A. Gray. 
In sheltered and humid herb-mats, very rare in our area. 
Disko: Recorded from Godhavyn, 69°14’ (Sor.) but afterwards vainly searched

a 
Mainland: Portusit Island N. of Kangatsiaq, 65°27 
(W. & H.). 
(Kr.!), Itivneg, 66°58’

Covered by thick layers of snow in winter. The specimens from 
Portustit were fruiting. 
Ji 4. Polystichum Lonchitis (L.) Rorn. 
In sunny and most herb-mats, on rock-ledges and in bushland.

I 5. Cystopteris fragilis (L.) Bernu. 
On sunny, not too dry rock-ledges, in fissures, herh-mats, and 
thickets, but not at all everywhere; yet found in numerous favourably 
exposed localities, throughout the whole area. 
Chiefly in the lowland, but also higher up now and then. Widely 
distributed species without northern or southern limit in Greenland. 
Occurs in several forms according to the quality of the habitat. 
Abundantly fruiting. 
Rhizome and buds always covered by snow. 
I 6. Woodsia ilvensis (L.) R. Br. and var. alpina Botton 
Ascu. & GRAEBN. 
On rocks and often on gravel and similar barren places. Very com- 
mon throughout the whole area, but rarer on basalt than on gneiss. 
Most frequently the variety occurs, the main-species being limited to 
the most favourable conditions and is likely not to be found in the 
northern part of the area.
