We will use Citrus Flowers and Fruits to represent a Syncarpous Gynoecium.
Note the large, lobed appearance of the Stigma. This
indicates that the Gynoecium is probably Syncarpous.
Can you find Coalescence in any other floral organs?
Young Fruits can be seen on Flowers which have lost their
other floral organs, except for their Sepals.

Count the Number of Carpels!! Boy
is this gettind tedious or what!!!!!!!!
Just
in case you haven't gotten it, or don't want it,
the number of Vascular Bundles in the Style equalled
the number of Carpels in the Ovary which equalled
the number of Carpels in the Fruit.
Consequently, the Gynoecium contained 10 Carpels and was Syncarpous!!!!
