Produktbeschreibung
Excerpt from Genera Lichenum: An Arrangement of the North American Lichens This is it final report to the friendly correspondents of the author on the specimens which, for many years, they have sent to him for determination. And such determination implying ii certain arrangement, the book is further a report upon what, after much labour, has commended itself to him as the best-ascertained, systematic disposition of the Lichens. It was intended, in an introductory chapter, to attempt some reckonius of the more weighty, published opinions as to the position, and rank of these plants in nature; to review cursorily the development of the system, and several of the varying interpretations of it; and to consider finally, more at large, the systematic value of the anatomical characters, as especially of the spore characters; but prolonged indisposition, resulting from overwork, and rendering it necessary to depend upon a friend for the correction of the press, and to shorten as much as possible these prefatory observations, leaves it open only to say that the author´s point of view here, remains in general the same with that indicated by him already in print, on another occasion; and that the further exemplification of what is there advanced must now speak for itself. It yet appears proper to and that the result of a long study of inter-tropical and related lichens, pursued by the writer, at first under the friendly direction of Fries, and Montague, as afterwards in the light of the more recent lichenology, and, especially,, of the very instructive writings of Nylander, - was a persuasion that, so far as system was concerned, the later liehenographera had scarcely the advantage which it was assumed that they had over the earlier; that not a few of the changes of form proposed by the former were either insufficiently grounded, or comparatively unimportant, if not now erroneous; and that there was, in a, word, nothing as yet to compare, in solidity and thoroughness of construction, with the system (as understood in its principal outlines, and as embracing, it afterwards proved, the Collemaceous lichens) of Fries.
