 understand the structure and modifications of the 

 spikelet. This primer is really an elementary study 

 of the morphology of the spikelet. [Morphology is a 

 branch of science that treats of form and structure. 

 The study of the morphology of the spikelet enables 

 one to recognize its various organs under whatever 

 form they may assume.]
