been carefully selected, either from highly interesting 
new plants, or those which will not admit of cultivation, 
as some of the Rhexias , Lupinus , Gerar dia, &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 will 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, which 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 I had it from is generally men- 
tioned. Those I have adopted without seeing them 
myself in either state, and which are but fewg 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 careful 
references to authors and good figures will amply supply 
this deficiency. 
In the alteration made in the systematic arrangement.
