74 Мовтем P. Porsitp. 
A southern type, the northmost habitat on Nügssuaq peninsula 
70°40’ (P.). South of 64° common, but especially attached to the outer 
land (Ros.). 
From the shore ascending to at least 800 m. 
Flowers lately and fructificates but scarcely. 
Covered by snow during winter. 
| L 139. Cerastium arvense [.. 
S. Kangerdluarssuk 67°5’ (W. & H.) among Salix and Archangelica. 
Decided southern type, found only once in Greenland. 
I 140. Cerastium alpinum L. 
As Stellaria longipes in all sorts of soil, and just as widely distri- 
buted as that species. | 
Varies infinitely as to size, the length of the internodes, pubescence, 
form and size of the leaves, the form and construction of tuft, the posi- 
tion of the shoots erect or decumbent. 
No doubt most of these forms are ecological, perhaps some of 
them hereditable, but this can only be settled by experiments in culti- 
vation. In manured soil round the new buildings it occurs in great 
quantities, especially the form procerum Lange, among grasses, these 
finally overshading and choking it. 
Abundantly flowering and fruiting. 
On the hills very often snowless during winter. 
I have found it with expanded flowers (hibernated!!) in April 
(a month before it was flowering in the lowland) on the top of a Nuna- 
taq from the interior of Disko, ascended to 1300 m. 
V 141. Melandrium apetalum (L.) Fenzı. (incl. f. arctica 
I, Di, Ol Le Sv. Vet: Ak, noeh, 1509 jo. 188) 
On sand gravel, clay, bare spots on poor heath on newly formed 
moraine and at the borders of brooks from the inland-ice. 
Disko: The northland to Nordfjord; on the eastern side to about 69°50’ 
and in the valleys common. (P.). On the south coast not seen, not even ascended. 
Hare Ø: (Nath.; P.). 
Mainland: On the coast of Nugssuaq peninsula common down to 70°, there- 
after only at Ege near the inland-ice 69°42’ (P.) and Claushavn 69°5’ (В. Br.). 
A decided northern type; the above-mentioned places repre- 
sent the hitherto known south limit. 
Ascends the hills to the snow-line.
