 an account of the native plants of some particular 

 country, has become popular in the Linnaean school 

 of Botany, and is now universally adopted. Books 

 bearins: this title are almost innumerable, while their 

 scope and their merits are equally various. Some 

 are little more than catalogues of names ; others are 

 elaborate histories of the vegetable productions of 

 particular districts, more or less extensive; and many

 at least of those requiring particular elucidation. 

 The utility of such publications has been much con- 

 troverted ; but it depends, like that of other works, 

 on the excellence of their plan and execution. A 

 mere list of the plants of any country, if accurate 

 and complete, has its appropriate value ; more espe- 

 cially when it contains the discriminative charac- 

 ters by which such plants may be ascertained. But 

 a Flora may also be made a vehicle for the natural, 

 medical, and economical history of a country, like 

 the Flora Lapponica of Linnaeus ; though such ob- 

 jects cannot with propriety enter into the plan of a 

 Flora of any highly improved or well-known region. 

 We now therefore expect, under this title, a work
