ON GENERA AND SPECIES. 51 
furnished by me, some from living plants from the garden, 
and others from herbarium native specimens. The draw- 
ings being highly appreciated by Sir W. Hooker, Mr. 
Bauer freely placed them in his hands for publication, and 
in 1842 a splendid volume consisting of 120 plates was 
completed,* each plate containing natural and highly mag- 
nified portions of fronds, exhibiting in different states 
the fructification and venation, accompanied with corres- 
ponding letter-press, giving the characters of each genus:

from Presl's * Pteridiae Pteridographia,” and twenty being

The learned editor, however, says he reserves for him- 
self the power of rejecting such of them as on further 
With regard to that point he also says, “so completely do 
the ideas of Dr. Presl accord with my own, in regard to 
the limits of many genera that I should do him injustice 
were I not in many cases to quote his characters verbatim, 
and indeed the more attentively I study his book and com- 
pare the descriptions with the plants themselves, the more 
satisfied I am that he has produced a work that will not 
easily be surpassed for accuracy of, and clear and per-

In 1854 appeared the tenth volume of his work entitled 
“ Icones Plantarum," containing 100 figures of new and 
rare Ferns, which was soon afterwards followed by another 
volume called a “Century of Ferns.” This was followed 
by *Filices Exotice,” consisting of 100 plates, which gave 
place to another volume entitled “ Garden Ferns,” contain-
