"Nowhere in the world are Lichens more conspicuous than in the Falklands. The beautiful Usnea melaxantha, also a native of the arctic regions, forms a miniature shrubbery on the tops of naked rocks on the hills; while their sides are coated with many species, almost invariably identical with those of Great Britain. Along the sea beach grow many species of this group, especially a pendent Ramalina, very near the R. scopulorum of Europe, and attaining a length of eight inches: it hangs so copiously from the rocks as in many places to cover them entirely.
