ar imperfect flowers, of which the additional
carpels are the only traces, but this explanation seems forced.

=Increased number of flowers in an inflorescence.=--This happens
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.[463] 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.
