The Flora of Disko Island and Adjacent Coast of West Greenland. 69 
other hand it was absent here in 1918 (E. P.). This seems really to be 
the fact, too, in most of the other places; it may not yet be acclimated, 
and thus it cannot be counted among the real Greenlandic plants. 
I 123. Polygonum viviparum L. 
In all sorts of soil, in heath, herb-slopes, copses and fell-field, on 
sand and gravel and very often in manured soil. 
Very common throughout the whole area. 
Widely distributed in Greenland, with neither northern nor southern 
limit; ascending from the shore to considerable altitudes. 
Abundantly flowering and forming bulblets in great quantities. 
In rich soil fruits are developed lately in good summers. 
Most of the habitats are covered by snow during winter. 
i 124. Koenigia islandica L. 
Most frequently found in and by running water, in shallow places 
in brooks, among small stones at the borders of brooks and lakes (pools); 
in manured drains at inhabited places often forming extensive patches; 
also to be found in moist places on the heath and in moss-bogs. 
Widely distributed in West Greenland without south limit; the 
northern limit unknown, but to be settled north of 73°. 
Flowers and fructificates abundantly. 
Its habitats are covered during the winter, usually by ice. 
XVIII. Caryophyllaceae. 
Sagina. The specimens of this genus are usually neglected by the 
collectors (also by us) because of their diminutiveness, and thus I have 
nothing of importance to add to the hitherto known facts of its distri- 
bution. 
A 125. Sagina saginoides (L.) Datte Torre (S. Linnaei Pres). 
Disko: The south coast, Lyngmarken 69°15’ (Bg.). 
Mainland: N. Isortog 67°15’ (Ros.). 
A southern type, the above mentioned habitats the only ones 
reported from our area and temporarily the north most in Greenland. 
No doubt rare. 
Abundantly flowering and fruiting. 
I 126. Sagina intermedia Fenzt (S. nivalis Fr. p. p.). 
In sandy and clayey spots on heath and fell-field, often at the sea- 
shore, but also as an inland-plant, ascending the hills.
