 Diospyros kaki is typically a dioecious species which means that trees are either male or female but some cultivated varieties are monoecious in which case both male and female and even perfect (male+female) flowers can be found on the same tree.The flowers have four crown-shaped sepals and four petals that form a large calyx.All varieties (parthenocarpic) will produce seedless fruit in the absence of pollination, but their pollinated flowers will produce more fruit riddled with seeds.
