Orchid flowers have three sepals, which form the outside of the bud before the flower opens, two
petals and a third modified petal called a “lip”. Other familiar plants that have this 3/3 structure are
lilies and irises. Orchid flowers have their male and female reproductive parts (anther and stigma)
fused into a single structure called the “column”. The column is unique in the plant kingdom and is
the identification characteristic delineating the orchid family.
