HOW TO USE THE KEY AND FLORA 3 



Eeferring now to the genus, it is found that there is only- 

 one species and that one agrees with the specimen in hand. 

 It is therefore Convallaria majalis, and the name (as indi- 

 cated by the L. which follows it) was given by the great 

 Swedish naturalist, Linnaeus.^ 



The author does not believe in spending much of the school 

 time of a class upon identifying species, but would rather 

 recommend comparative studies of as many plants of a group 

 as are accessible, and making these studies thorough enough 

 to bring out fully the idea of the family, the genus, and the 

 species.^ The descriptions in this flora may be used as a 

 check on the cruder ones which the pupil is first to frame for 

 himself. 



1 It will greatly simplify matters if the teacher throughout selects for 

 examination only such species as are described in the flora. 



2 The teacher will find abundant suggestions for such a course In Spalding's 

 Introduction to Botany, pp. 152-260.
