Increased nnmber of flowers in an inflorescence. This hap- 

 pens generally as a result of over luxuriant growth, 

 and scarcely demands notice here, being rather referable 

 to variation than to malformation. The increased 

 number of florets in the spikelets of some grasses has 

 already been alluded to (p. 351). Thus spikelets of 

 wheat occasionally produce more than the three florets 

 which are proper to them.^ It will be remembered that 

 in this as in many other grasses there are rudimentary 

 florets, and it is no matter for surprise that these 

 florets should occasionally be fully developed.
