been carefully selected, either from highly interesting 

 new plants, or those which will not admit of cultivation, 

 as some of the Rhexias, Lupinys, Gerardia, &c. As 

 the plates were executed during the progress of the 

 work through the press, references to them could not 

 be inserted in the proper places ; but as the plates 

 themselves refer to the pages of the work, it \\ill be 

 easy to supply this deficiency. 



Particular attention has been paid in describing the 

 soil, situation, and range of country each species is 

 found in, vvliich will be found very useful to the practi- 

 cal botanist, and especially so to the cultivator of those 

 plants. 



After the usual sign of duration, and the time of 

 flowering, each species has been faithfully marked 

 whether I have seen it myself in a living state {v. v.), 

 or only in a dried specimen {v. s.) ; in the latter case the 

 name of the herbarium J had it from is generally men- 

 tioned. Those I have adopted without seeing theni 

 myself in either state, and which are but few, I have 

 marked ( + ) . 



To each species a short note has been added, respect- 

 ing the colour and size of the flower, the habit of the 

 plant, or some other interesting subject illustrative of the 

 species. 



Very full descriptions have been given of only some 

 of the most interesting new species, as the limits of the 

 work would not admit of it in general. The carefril 

 references to authors aud good figures will amply supply 

 this deficiency. 



In the alteration made in the systematic arrangement.
