ON GENERA AND SPECIES. Oi 



furnisliud by me, some from living plants from tlio gardon, 

 and others from lierbarivim native specimens. The draw- 

 ings being highly appreciated by Sir W. Hooker, Jlr. 

 Bauer freely placed them in his hands for publication, and 

 in 1842 a splendid volume consisting of 120 plates was 

 completed,* each plate containing nataral and highly mag- 

 nified portions of fronds, exhibiting- in different states 

 the fructification and venation, accompanied with con-es- 

 ponding letter-press, g'iving the characters of each genus : 

 there are on the whole 135 genera, many being derived 

 from Prcsl's " Pteridiao Ptoridog-raphia," 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 reg-ard 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 g-enora 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 ho has produced a work that will not 

 easily be surpassed for accuracy of, and clear and per- 

 spicuous, arrangement." 



In 1851' appeared the tenth volume of his work entitled 

 " Icones Plantarum," containing- 100 figures of new and 

 rare Perns, which was soon afterwards followed by another 

 volume called a " Century of Ferns." This was followed 

 by " Filicos Exotica;," consisting of 100 plates, which gave 

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



* Tiie drawings for tlie latter part of this work were executed hy the 

 equally eminent draughtsman Mr. AV alter Fitch ; this was consequent 

 on the health of Mr. Bauer having failed.
