The Flora of Disco Island and Adjacent Coast of West Greenland. 23 
being probably either hybrids or chance mutations, endemic species 
in an embryo state. 
They are indicated thus: e 
The distribution in the adjacent parts to the south of the area is 
briefly subjoined, quoted almost exclusively from L. KoLtpERuP RosEn- 
vinGrE’s carefully revised “Andet Tilleg ete.”. As to the distribution 
to the north of the area we have made use of ABRomert’s revision of 
Vanuorrer’s collections, but especially of our own observations pub- 
lished in “Vascular Plants 71°—73°*

I. Polypodiaceae. 
1 1. Dryopteris Linnzana C. Cur. (Aspidium Dr. (L.) Baume. 
In herb-mats and copses, often in the shade under rocks, but al- 
ways in favourably situated, sheltered places; especially near the hot 
springs. 
Disko: The south-coast from Laksebugt to Skansen, from many places 
(several collectors). Disko-Fjord: the north-coast, rarer; the northmost at Kuaner- 
so6q 69°32’ (P.). 
Mainland: N. Isortog 67°10’ (Ros.), Prastefjeld at Holsteinborg (W. & H.), 
(P. & B.}. 
A decided southern type; in vain searched for in a great many 
favourably situated places in the fjords south of Disko-Bay. South 
of the here mentioned place from 65°64’ and (according to Rosenvinge) 
common south of 63°, 
All the mentioned places in the lowland. Usually sori are found, 
but sporangia only seen on specimens from KuanersoK. 
During the winter under a thick cover of snow. 
Vv 2. Dryopteris fragrans (L.) Scuorr. 
On sheltered, sunny, not too dry rock-shelves; more scarce on 
stony soil in the heath. 
Disko: Very rare, hitherto only from the vicinity of Godhavn (V.) and basalt- 
rocks behind Evqitsog in Diskofjord 69°32’ (P.). 
Mainland: Rather common in the gneissic tracts, especially at some distance 
from the outer coast; from 70° at least to 67°. Still, in the fjords inland from Hol- 
steinborg, rather common. The southmost locality hitherto known at ca. 64°44” 
In Greenland a decided northern type; in U.S. A., however, to 
be found down to New England and Minnesota.
