BRANCHING AT INFLORESCENCE 

 Figure 13. In this case, branches have 

 developed at the inflorescence. These inflor- 

 escences often produced no fertile flowers and 

 the vegetative branches often grew to consid- 

 erable length and remained green long after 

 the remainder of the plant had turned brown. 



A MODIFIED SPIKE 



Figure 14. Great variation in the extent 

 of abnormality of the spikes was found. In 

 the extreme cases branches were given off at 

 the nodes instead of spikelets; others were 

 nearly normal. Very little seed was produced 

 by the greatly modified spikes.
