POLYCARPELLARY. A typical carpel consists of three 
parts, the apical portion called the Sricma, a long 
slender portion connecting the stigma to the lower part 
called the Srynz, and a box-like 
structure at the bottom called the a) 
Ovary. Inside the ovary are struc- B 
tures called OvULES, borne on an 
outgrowth of the margin of the 
carpel called a PLACENTA, - ane 
If the placenta simply projects a

the ovary the ovary is said to pos- : ?

plete. Sometimes the stigmas are free, in other cases 
the styles as well may be free. In these cases it is 
easily seen how many carpels are present, but when 
the fusion is complete it is more difficult. Only by a 
careful examination of the ovary is it possible to tell the 
number of carpels present.

fuse to forma unilocular ovary and the placentas are 
projections of the ovary wall, as described above, the 
placentation is said to be Partutan. The number of
