'I'lu' Flura uf Diskd Island and Adjacent Coast of West Greenland. 75 



Abiindantly flowering and fruiting. 



No doubt normally liibernating snow-covered. 



V 142. Melandrium affine J. Vahl. 



On sand, gravel, clayey banks, fell-field and in bare spots on the 

 heath, on rocks, often in manured soil. 



Disko: Everywherc vory coinnion (P.). 



Hare O (P.). 



Mai ni and: Nugssuaq peninsula and tlic land easL of Disko-Bay, common. 

 By Kruuse recorded "very rare" in the arciiipelago of Egedesminde; this does not 

 agree with our observations. In N. Strømfjord common, especially on the southern 

 side, as well as on the hills (P. &: E.); likewise common in the fjords inland from 

 Holsteinshorg (P. & E.). 



A northern type, south of the area only observed a few times. 

 The sonthern limit at 65°38'. 



Flowers and fruits abundantly. 



Hibernating snowless, at any rate in alpine piaces. 



V 148. Melandrium triflorum (R. Bu. i J. Vahl. 



In piaces similar to those of preceeding one and with the same 

 distribution, but generally rarer, but often locally better developed 

 than affine. Seems to prefer manured soil to a greater extent than 

 the preceding one, and here it becomes tall and vigorous. 



In the field often very difficult to distinguish from affine., though 

 always more glandular-hairy than that species. On vigorous speci- 

 mens the glandular-hair can be developed to such a degree that the 

 piants are densely covered by adhering sand and dust. 



But in the seeds we have a never failing character of distinction 

 (Cfr. Lange and Abromeit). 



As the preceding, a northern type and almost with the same 

 southern limit, about 65''40'. 



I 144. Silene acaulis L. 



In almost all sorls of soil: sand, gravel, open spots in Llie heath 

 and bogs, in crevices and shelves. In quick-sand it often forms spots 

 more than one meter in diameter. 



Very common throughout the whole area. 



Widely distributed in Greenland with neither northern nor southern 

 limit; from the sea-shore to the snowline. 



Abundantly flowering and fruiting. 



Often snowless during winter.
