HOW TO USE THE KEY AND FLORA 3 



Referring 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. 1 



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. 2 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.
