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.
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).
(Sedge family), Juncaceae (Rush family), and some other monocotyledons with inconspicuous flowers.
In the immediate vicinity of water the sedge (Carex physoides) grows, and sporadic patches of Allium.
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.
