Calcicole and Calcifuge Species.Plants which invariably inhabit calcareous soils are sometimes termed calcicoles; calcifuge species are those which are found rarely or never on such soils.
In relation to the latter theory, it is pointed out that some markedly calcicole species occur on sand dunes; but this may be due to the lime which is frequently present in dune sand as well as to the physical dryness of the soil.
In England, the number of calcicole species is greater than the number of silicolous species.
The montane calcicole bryophyte flora is also outstanding and includes a number of species not present on other selected sites.
