AMERICAN LICHENOGRAPHY. 



It is proposed in this sketch to give a brief account of such works 

 on the subject of Lichens published in this country as have fallen un- 

 der the writer's observation. The study of this branch of botany, 

 interesting as it is, is confined to a few, who labor under great disad- 

 vantages, from the scattered nature of what has been published by 

 our own writers, and the absence of a complete American Lichenog- 

 raphy, brought up to the present state of knowledge, and based on 

 the modern views of the science. Several interesting local catalogues 

 have, however, been published, and Professor Tuckebman's valuable 

 Synopsis, published in 1848, gave a full and accurate view of the 

 Lichen flora of the northern part of the continent, so far as known at 

 that time. But very much has been discovered since then, and the 

 use of the microscope has imparted an entirely new aspect to the sci- 

 ence. A fresh impulse would doubtless be given to the study, and 

 many botanists would engage in the investigation of the Lichen flora 

 of our country, so vast, and as yet so imperfectly explored, could they
