As regards the flora the elevated position of parts of the county makes it the home of a number of plants which do not commonly occur in the South of England. Thus there are found on Exmoor the crowberry (Empetrum nigrum), the parsley fern (Cryptogramme crispa), and the oak fern (Phegopteris dryopteris). Asplenium septentrionale is found at Culbone; Listera cordata grows on Dunkery and near Chipstable; and the cranberry (Oxycoccus palustris) is said to occur at Selworthy and on the Brendons. On the other hand, Somerset likewise furnishes congenial conditions for those plants that love low-lying, marshy ground, and on the peat-moors in the Glastonbury district the flowering fern (Osmunda regalis) and the bog myrtle (Myrica Gale) are met with. Within the British Isles the following are found only in Somerset: Dianthus gratianopolitanus, Hieracium stinolepis, Verbascum lychnitis, and Euphorbia pilosa. Arabis stricta occurs only on the limestone near Clifton; Helianthemum polifolium is confined to Somerset and Devon; Pirus latifolia to Somerset and Denbigh.[2]
