Pollinating an orchid: Photos of relevant structures
This first photograph of a Phalaenopsis bloom shows the flower's column, with stigma and anther, and the flower's lip. The lip's complex shape and coloring helps to attract pollinating insects but serves no purpose in the reproductive process itself:
This next photograph of the same flower with the lip removed clearly exposes the flower's column and reveals the stigma: the cavity or depression inside of which the pollenia need to be placed:
Below, the anther cap has been removed from the column by nicking it off with a toothpick, and the pollenia have been extracted with tweezers. A toothpick will work just as well:
Here, the flower's petals and sepals have been cut off to show only the flower's column and its stigma:
Finally, the mass of pollenia is pressed into the stigma, where a sticky substance helps to hold it in place. In genera where the sticky substance is thin or absent, many growers use saliva to wet the stigma before pressing the pollen mass inside.
The flower has now been pollinated, and only time will tell whether the pollination has been successful:
(Don't dismember the flower by cutting off petals and lip when you're trying this at home. That was done here only to show the relevant structures more clearly in the photographs.)
