The generic names are printed in capitals : the specific 

 names in italics ; the English name, when the plant has 

 any, is parenthesised in Roman. When species are des- 

 cribed, the descriptions are in Roman. If an English 

 name is added to one species only, the same name may 

 be given to the other species of that genus, qualified by 

 some appropriate epithet. As the general name for carex 

 is sedge, I would call the carex plantaginea the broad-leaf 

 sedge, c. 



The first number preceding the generic names stands 

 for the number of the ciass, the second for the number of 

 the order. The first number following the generic names 

 refers to the natural order of Linneus, the last number 

 refers to the natural order of Jussieu. As Aster is in the 

 eighteenth class and second order in the artificial system; 

 the forty-ninth natural order of Linneus and of course 

 possesses tonic aiijd secernant stimulant properties ; and 

 in the fifty -fifth natural order of Jussieu. 



FOR THE GENERA. 



When the asterisk (*) is prefixed to one or more gene- 

 ric names, set down below the end of an order, it implies 

 that these genera are not described here, but stray as it 

 were into this class and order by departing from the ar- 

 tificial character Therefore \vhen a plant thus runs 

 astray, so as to lead us to a wrong place in pursuit of its 

 name, and of course when we cannot find an appropriate 

 generic description for it> we go back to where each of 

 these asterisked or advertized genera respectively belong, 

 and read over their general generic characters until we 

 find the right name.
