Display device
In flowering plants, the display device is the entirety of all the organs that make a flower or an inflorescence attractive to a pollinator . The display device transforms the morphological unit blossom or inflorescence into the functional unit flower .
The floral display apparatus consists of organs of the flower, usually the petals , but also sometimes sepals or stamens . The extra-floral display apparatus is made up of mostly colored bracts .
Colored leaf organs in the flower area, which serve to attract pollinators, are called semaphyll .
The attraction of pollinators in the sense of a display device also serve so-called show flowers , which - enlarged and mostly sterile - appear on the periphery of inflorescences of some species ( e.g. in the genus Viburnum ).
In eucalyptus the stamens form the display apparatus
In Spathiphyllum , a bract forms the display device and is by definition a semaphyll.
