LIST OF GRASSES. 



17 



A frequent reference to figures 1, 2, 3, 4, and 5, will 

 greatly aid the reader in becoming familiar with the 

 technical terms applied to the organs or parts of the 

 flower which it is desirable to understand, and by means 

 of which he will soon learn to distinguish the different 

 species more readily. 



In giving the scientific names, the first word that 

 occurs in parenthesis is the name of the genus ; the 

 second, that of the species ; as, for instance, in Timothy 

 (Phleum pratense), Phleum is the generic name, pra- 

 ten-se the specific. A genus often contains many 

 species. 



The grasses which are described more or less 

 minutely in the following pages are named in
