ZIGZAG CULMS APPROACHING NORMAL CULMS IN APPEARANCE 
These plants were selected to show how closely some zigzag plants approach normal plants in 
appearance. Their dwarfness is not very noticeable. Note the number of internodes that are 
arched away from the point of leaf attachment. Upon comparison with the normal culm shown 
in Fig. 12 the zigzag character which is here less distinctly expressed becomes evident. (Fig. 16.)
