Increased number 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.
