The Liverworts, Mosses and Ferns of Europe
Keys to the entire European bryophyte and pteridophyte flora in a single, 500-page volume - hardly surprisingly there are no species accounts! But there are copious drawings and alternative keys for some groups, and each species entry decribes its status on Britain and Ireland.
||English, revised and edited by T.L. Blockeel
||All the European species known at the time.
||Under a Compound Microscope (also useful to examine under a Stereo Microscope).
||Most bryophytes require microscopic examination of leaf shape and cell structure. Pteridophytes can largely be identified on sight, perhaps with the aid of a hand lens.
