published in 1636; Eelhan's "Flora Cantabrigiensis/' published 

 in 1802; Ray's "Synopsis Methodica Stirpium Britannicarum," 

 published in 1724; and a host of other botanists. 



It is purposed as an "addenda" to the "Natural History of 

 British Grasses," to describe those Exotic species that are 

 remarkable, either as ornamental plants, useful as introduced 

 species for the agricultural community, or for their domestic 

 interest. 



In conclusion, I take this opportunity of soliciting of those 

 whose pursuits and inclinations lead them to a study of the 

 Grasses, their aid in specimens and information; for let it be 

 borne in mind, that every one has power to render valuable 

 aid, and in a work like the present, the more assistance that 

 is given, the better able will the author be to produce a work 

 worthy of that patronage which, from its cheapness, must have 

 a wide circulation.
