REPRODUCTION BY SEED 179 
In the raceme (Fig. 75) the youngest flowers are 
at the apex. In some cases the stalks of the flowers 
are so adjusted in length that all the flowers are 
brought to the same level—eg., the corymb of the 
Crucifers (Fig. 76). The whole mass of small flowers 
is thus made more conspicuous. After fertilization 
the axis of the inflorescence lengthens, separating

the fruits. When the flowers of the raceme are 
separated by long internodes they are large—e.g., fox- 
glove. 
The number of flowers is increased when the axis of 
the raceme branches, and this type—the panicle—is found 
in the lilac and horse-chestnut among insect-pollinated 
flowers, and many grasses among the wind-pollinated 
ones. In the clovers and medicks the axis is short, and
