Sometimes the trees grow in grassland, and sometimes on “herb-
ílats;” occasionally the wood-floor consists of mosses. In grassland
the commonest species are Agrostis vulgaris, Aira flexuosa and An-
thoxanthum odoratum and other more scattered Gramineæ. Where
the herb-flat formation is dominant many different species occur,
especially Spirœa ulmaria, Angelica silvestris, Rubus saxatilis, Leon-
todon autumnalis, Geranium silvaticum, Bartschia alpina, Myosotis
arvensis, Alchimilla vulgaris, Fragaria vesca, and others. Trientalis
europœa grows here and there in woods in East Iceland only. Where
mosses are dominant on the wood-floor the vegetation consists chiefly
of Hylocomium (H. Jónsson, 1900, p. 76). On the whole, in coppices,
scattered individuals of the numerous species from the different form-
ations in the neighbourhood may be found.
