the number of carpels is fewer than ordinary, there is no 
deviation from the normal structure. 
Fruits with one series of carpels may be regarded as 
reductions from a more generalized multiseriate type. The 
interest of a case such as I have described is the proof that 
a tendency to revert to the more generalized type may still be 
latent.
