Armeria marilima, as also Luzula, Elyna, etc.; in damp home-fields
are found Caltha palustris, Cardamine pratensis, Koenigia islandica,
Montia riuularis and different Carices. Moreover, a great many spe-
cies often immigrate from the plant-formations of the neighbourhood;
in some places, in badly kept home-fields, even swamp vegetation
and willow-coppices or heather may be met with in patches. The

farm-buildings are, as a rule, in the cenlre of the home-field, and

Poa annua and P. triviatis; quite near to the home and stables grow
Stellaria media, Capsella bursa pastoris, Pohjgonum aviculare, Rumex
domesticus, etc. Around farmsteads in the vicinity of the sea, and
on islands, are often found in addition Cochlearia officinatis, Cakile
maritima and Atriplex patula. In Iceland the walls and roofs of
peasants’ houses are generally built of turf and are therefore over-
