low, densely-tufted growth and the glabrous, obtuse, rosette-leaves, 

 while the floral shoots are somewhat downy and glandular, and the 

 flowers few but large (see Fig. 12). 



76. S i 1 e n e a с a u 1 i s L. — Very common everywhere on heaths, 

 rocky flats and on rocks. 



77. Viscaria alpina (L.) Fenzl. — Amitsuarsuk (72°23') in the 

 lowland; one individual. 



From J. Vahl's printed labels Lange records "common to 72° 48', '' 

 i. e. Upernavik's latitude. This is, however, not correct. Even on 

 southern Disco it is restricted to the most favourable localities, is 

 absent from northern Disco and Hare Island, has been found once

only on the shore of Nugsuaq's Vajgats-coast and — so far as I 

 remember — the Botanical Museum in Copenhagen contains no speci- 

 mens from more northerly localities than 70^25' (Karajak Nunataq). 



78. Melandrium ape tal um (L.) Fenzl. — Common on moraine 

 material and rocky flats, in river-deltas and in open spots on the heaths^ 

 especially in the coastal districts and in the mountains. On the other 

 hand it is absent from the dense heaths at the heads of the fjords. 



79. Melandrium affine J. Vahl. — The most common species 

 of the genus ; occurs everywhere in many different plant-communities. 



80. Melandrium triflorum (R. Br.) Vahl. — In similar loca- 

 lities as the preceding, especially near the shore. Gathered in the 

 interior of Lakse Fjord, Ingnerit Fjord and at Igdlorsuit. It is pro- 

 bably not rare.
