A STUDY OF THE RICE HEAD 331 



projections at the base of the kernel. The kernel is flat- 

 oval in shape with lines or small depressions running from 

 top to bottom. The spikelets are placed singly at various 

 intervals along the branches. Figure 29 shows the rice head. 



Equipment. Heads of rice for each member of the 

 class. 



Directions. Make a drawing of the entire head of rice. 

 Remove a spikelet and make a drawing of it. Draw the 

 outer glumes ; a single flowering glume ; and the palea. 

 Make a drawing of the kernel showing the broad or side 

 view, one showing the germ side, and one showing the cross 

 section. Make all drawings at least four times natural 

 size, except the one of the panicle. Make them in careful 

 detail and show all the different parts.
