Preface. ix 



Latin, the derivation of the generic names is given, as a 

 knowledge of the signification of a name materially assists in 

 impressing it on the mind, or recalling it on seeing the plant 

 to which it has been given. The specific names of frequent 

 occurrence, with their meanings, are included in the glossary 

 of terms. The relative size of the woodcuts to the plants they 

 represent is appro ximatively given, in order to enable the 

 reader to form a better judgment. 



The Second Part, devoted to Practical Gardening, calls for 

 no special remark, further than to say that it was not written 

 for the guidance of those advanced in the art of cultivating 

 and arranging plants, and laying out a garden. 



A companion volume, devoted to Greenhouse and Hothouse 

 Plants, is contemplated, should this meet with sufficient 

 favour to justify the belief that such a work is needed. 



In conclusion, my best thanks are due to Professor Oliver 

 and Dr. Masters, who have materially assisted and advised 

 me ; but I more especially wish to record my obligations to 

 Mr. J. Gr. Baker, F.L.S., who kindly checked all the proofs as 

 they issued from the press, thereby correcting many important 

 errors which, in the absence of an adequate library, I should 

 not have detected ; and also kindly permitted the use of his 

 researches in the petaloid Monocotyledonous plants.
