The Flora of Disko Island and Adjacent Coast of West Greenland. 25 
The species widely distributed, with northern limit in Greenland, 
but the precise limit cannot yet be settled, undoubtedly occurring 
north of 74°. 
Ascending the hills certainly to the snow-line. 
Abundantly fruiting. 
Rhizomes and buds covered by the withered leaves which are 
loosened by the pressure of the snow-cover, being squeezed together 
in a lump that contributes to protect the rhizome and the buds till 
the snow melts or drifts away. 
Certainly snowbare now and then. 
Vv 7. Woodsia slabella R. Br. 
On warm, moist rock-ledges often near waterfalls, rarer on grav- 
elly soil. Rare, only occurring in small associations and often as isolated 
specimens only. 
No doubt often overlooked. 
Disko: Near Godhayn. On rocks near a spring in Osterdal (Th. P.) Blasedal 
near Rede Ely on basalt gravel (Ekblaw). 
Diskofjord: The basalt-rock at Evqitsoq (P.), Kuanerssuit (P.). 
Mainland: Eqe 69°45’ (P.), Igdluluarssuit 69°50’ (P.), Christianshaab (V., 
Th. H.), Tasiussarssuaq (Bg.), Sofiehavn (BI.), the mainland south of Nivaq Fjord 
68°30’ (P. & E.), Kangerdluarssuk E. of Agto 67°59’ (E. P.), N. Isortog 67°15’ (V.), 
Ikert6q (V.). 
Just as Dryopteris fragrans this species, too, is a northern 
type in Greenland, although it is found far southwards in U. S. A. 
Hence in W. Greenland the southern limit is at the last mentioned 
locality. 
On the other hand it has been found in E. Greenland down to 
61°30’. 
All the above-mentioned localities are in the lowland, but south- 
wards it is likely to be found at considerable altitudes. 
Abundantly fruiting. 
No doubt always covered by snow in winter or enclosed in ice. 
II. Ophioglossaceae. 
it 8. Botrychium Lunaria (L.) Sw. 
On warm and somewhat moist slopes, in herb-mats often in shade 
under other vegetation. 
Disko: Environs of Godhayn 69°15’; from Engelskmandens Hayn to Kuanit 
gathered at several places by various collectors.
