ON GENERA AD SPECIES. 5 



furnished by me, some from living- plants from the garden, 

 arid 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 : 

 there are on the whole 135 genera, many being derived 

 from Presl's " Pteridiae Pteridographia," and twenty being 

 named and described by me as new. 



The learned editor, however, says he reserves for him- 

 self the power of rejecting such of them as on further 

 examination he may consider himself justified in doing. 

 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- 

 spicuous, arrangement." 



In 1854 appeared the tenth volume of his work entitled 

 " Icones Plantar-urn," 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 Exoticae," consisting of 100 plates, which gave 

 place to another volume entitled " Garden Ferns," contain- 



* The drawings for the latter part of this work were executed by the 

 equally eminent draughtsman Mr. Walter Fitch ; this was consequent 

 on the health of Mr. Bauer having failed.
