Such is Sherbrook Valley, and there are many similar valleys north of Cannock where are found many of the rarer sphagnums, such as Sphagnum viride. Again west of Cannock are the remains of what were formerly extensive bog lands, such as Norton bog, where is the rare S. tenellum, and near Uttoxeter, in the deep and treacherous Chartley bog, are many of the sphagnums and other moisture loving species, such as the rare Polytrichum strictum. The woodlands of the county, though ex- tensive, are usually dry and rarely the homes of any but the more com- mon species ; but some of the woodlands around Gnosall and Norbury yield rarer mosses, such as the hair moss Polytrichum graa'/e, Bryum uligi- nosum and Fontinalis squamosa and other rare species ; and the rich wood- lands of the south-west have yielded some of our rarest species, such as Fumaria ericetorum, Pterygophyllum lucens and the rare Heterocladium 60
