PREFACE TO THIRD EDITION. 



THE present Edition of this work, though an endeavour 

 has been made to condense it by the suppression of 

 particulars of less importance, will be found to contain 

 about twenty pages more than the last. As regards 

 however, the great bulk of the matter contained in it, 

 it will be found otherwise to differ little. In fact 

 there was little perhaps to call for much alteration. 

 The great desideratum was to notice and describe as 

 far as possible the plants that have been newly intro- 

 duced. These, though many in number, comprise for 

 the most part such as are remarkable for their foliage, 

 as well as those the cultivation of which can only be 

 conducted successfully in the Betel-house. The most 

 of these I believe I have been enabled to specify, and 

 several of them to describe either in the body of the 

 work or at p. 594, at its close. 



For corrections and additional information in the 

 description of the Orchids I owe my best thanks again 

 to Mr. S. Jennings. For the advantage also that I 

 have taken of the valuable contributions of Mr. John
