BOTANICAL INFORMATION. 61 
“Tt is to be regretted that no general work exists, containing an 
enumeration of all these detached indications, and giving an estimate 
of the number of species in each genus at the time of its publication. 
*'The earlier enumerations of Ferns in Willdenow's * Species Plan- 
tarum,’ Sprengel's ‘Systema Vegetabilium,' and in Steudel’s * Nomen- 
clator, have become defective, and no longer suffice. Greville’s and 
Hooker's ‘ Enumeratio Filicum,’ in Hooker's * Botanical Miscellany,’ 
vol. iii., has never been completed; and Hooker’s ‘Species Filicum," 
which was commenced ten years ago, progresses so slowly, that its 
early completion can scarcely be hoped for. 
“ As by Kunze's death, which took place much too soon for science, 
his resolution of publishing a ‘Synopsis omnium Filicum’ has unfor- 
tunately not been fulfilled, I have resolved, in order to possess the 
means of reference to all published materials, to prepare, within a year, 
a Nomenclator of all Ferns (in the widest sense), published up to the 
end of the year 1854, which I propose to complete as speedily as possi- 
ble, unless the desire expressed by Presl in the preface to his * Epimelize 
Botanice,’ should be forthwith fulfilled, that some one should be found 
who, with complete materials and preparation, should undertake a task 
which must be considered the most important object of Pteridography, 
namely, a * Genera et Species Filicum,' according to the newest views. 
* As I wish to give the earliest intelligence of the work which I 
have undertaken, I subjoin some specimens, which will show the mode 
of arrangement, as well as the extent to which I propose to carry this- 
Nomenclator, and I request, for the use of science, that all pteridolo- 
gists will be good enough to assist me with counsel and material."
