The life cycle of an orchid is not essentially different from that of any other flowering plant. When the pollinator leaves one or more pollinia on the stigma, the pollen tubes germinate and grow down the centre of the column to reach the developing ovules in the ovary. This often causes the sides of the stigma to swell around the stigma and the en...
