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. 



V 7. Woodsia glabella 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 Godhavn. On rocks near a spring- in Østerdal (Th. P.) Blæsedal 

 near Rode Elv on basalt gravel (Ekblaw). 



Diskofjord: The basalt-rock at Evqitsoq (P.), Kuånerssuit (P.). 



Mainland: Eqe 69°45' (P.), Igdliiluarssnit 69°50' (P,), Christianshaab (V., 

 Th. H.), Tasiussarssuaq (Bg.), Sofiehavn (Bl.), the mainland south of Nivåq Fjord 

 68°3U' (P. & E.), Kangerdluarssuk E. of Agto 67°59' (E. P.), N. Isortoq 67°16' (V.), 

 Ikertoq (V.). 



Just as Dryopteris f ragrems this species, too, is a northern 

 type in Greenland, although it is found far southwards in l^ S. A. 



Hence in W. Greenland the southern limit is at the last mentioned 

 locality. 



On the other hånd it has been found in E. Greenland down ta 



erso'. 



All the above-mentioned localities are in the lowland, but south- 

 wards it is likcly to be found at considerable altitudes. 

 Abundantly fruiting. 

 No doubt always covered by snow in winter or enclosed in ice. 



II. Ophioglossaceae. 



J. 8. Botrychium Lunaria (L.) Sw. 



On warm and somewhat moist slopes, in herb-mats often in shade 

 under other vegetation. 



Disko: Environs of Godhavn 69°15'; from Engelskmandens Havn to Kuånit 

 gathered at several piaces by various collectors.
