The peat is different in character from that of northern Europe: cellular plants enter but little into its composition, and it is formed almost entirely of the roots and stems of Empetrum rubrum, a variety of the common crowberry of the Scottish hills with red berries, called by the Falklanders the " diddle-dee " berry; of Myrtus nummularia, a little creeping myrtle whose leaves are used by the shepherds as a substitute for tea; of Caltha appendiculata, a dwarf species of marsh-marigold; and of some sedges and sedge-like plants, such as Astelia pumila, Gaimardia australis and Bostkovia grandif ora.
ACORUS CALAMUS, sweet-sedge or sweet-flag, a plant of the natural order Araceae, which shares with the Cuckoo Pint (Arum) the representation in Britain of that order of Monocotyledons.
- Carex riparia, the largest British sedge, from 3 to 5 ft.
(Sedge family), Juncaceae (Rush family), and some other monocotyledons with inconspicuous flowers.
An extinct water-lily, Euryale limburgensis, belongs to a monotypic genus now confined to Assam and China; an extinct sedge, Dulichium vespiforme, belongs to a genus only living in America, though the only living species once flourished also in Denmark; an extinct species of water-aloe (Stratiotes elegans) makes a third genus, represented only by a single living species, which was evidently better represented in Pliocene times.
The name mocking-bird, or more frequently mock-nightingale, is in England occasionally given to some of the warblers (q.v.), especially the blackcap (Sylvia atricapilla), and the sedge-bird (Acrocephalus schoenobaenus).
In the immediate vicinity of water the sedge (Carex physoides) grows, and sporadic patches of Allium.
