A Manual Of British Lichens Containing Descriptions Of All The Species And Varieties C PDF Download

Excerpt from A Manual of British Lichens: Containing Descriptions of All the Species and Varieties, and Five Plates, With Figures of the Spores of One Hundred and Thirty Species, Illustrative of the Genera Undoubtedly one great drawback and hindrance to the study of this class of plants originates from a feeling, which is common among cryptogamic botanists, that its correct study is difficult and perplexing, and that the limits of its genera are ill defined, and are not characterised by features so manifest as to render the species assignable with tolerable ease to their proper genus. Another cause has originated from the want of a work, complete in itself, containing a full description of all the native species, and their classification simplified; and another from not obtaining a sufficiently powerful microscope, by which to examine them.
