THE LICHEN-FLORA OF FLORIDA. 
Catalogue of Species, with Notes, and also Notices of New Species. 
BY JOHN W. ECKFELDT, M. D., PHILADELPHIA, AND W. W. CALKINS, CHICAGO. 
The authors have undertaken the present paper in the belief that the 
facts and material in their possession should be published for the benefit 
of Hellenists generally and as a contribution to our knowledge in a little- 
explored field as regards the subject under consideration. True, numer¬ 
ous collectors have been over the ground and have been well rewarded; 
but, after all, each additional research brings to light new or rare species 
and demonstrates that all of us have as yet merely skirmished on the line. 
The finding of four or five new r species during the past winter by one of 
the authors, within a space less than ten feet square, only shows what to 
expect in the future, if proper efforts are made. The authors give 
herein no species not properly verified as being found in Florida, and, 
indeed, a large proportion are the results of personal collections. The 
determination has been entirely by the senior author, Dr. Eckfeldt, who, 
in doubtful or difficult cases, was so fortunate as to secure the valuable 
assistance of Dr. W. Nvlander, of Paris. The new species were deter¬ 
mined by the latter world-known Hellenist, and, if possible, full descrip¬ 
tions of these will be given. The number enumerated may seem large, 
and yet we venture to say that in time it will be increased one third or 
more. The geographical position of Florida, her physical relations past 
and present to the West Indies and the Antillean system; her climate 
and soil, as well as parallels of distribution found in her phenogamic 
botany, warrant our belief. The order of arrangement of the list will be 
that after Tuekerman (Genera Lichenum) and recent writers on special 
genera in Lichenology.
