So long as this fashion continues in Botany, and to my mind it merits no better name, onr 

 genera must %o on increasing, until almost every other species becomes the type of a genus, as it 

 seems scarcely possible to find half a dozen species, even in large genera, agreeing in so many 

 minute and unessential points, though dozens may associate in all ethers of really generic value. 

 This position seems td derive some support from the fact, that the first 120 genera of Rubiace^,' 

 in DeCandolIe's Prodromus, give an average of about 6^ species to each; while the same number 

 of genera of Compositae, give nearly 12, though that order, also, has been abundantly split into 

 small genera. That fewer would suffice I do not venture to assert, but, tried by this standard, it 

 certamly seems that the number of genera is large in proportion to the species. On this subject 

 Richard remarks, that "very often a genus is established, because a species under examination 

 presents some modification not found in another, or which had been overlooked by the author 

 who first traced the generic character, an event which must almost unavoidably happen in all 

 cases where there are but a small number of species in a genus or genera in a family to study." 

 Carefully studied characters, excluding all mere specific distinctions, or at least only introducing 

 them mto the natural character, will go far towards remedying this evil, which is gradually as- 

 summg so serious a form, that it is to be feared a re-Sction will take place and lead us into the
