Term:

Versatile anther
Definition:

A stamen in which the filament is attached to the anther above the base of the anther.
Notes:

This type of anther attachment allows the anther to move when it is touched by a pollinator which may facilitate the transfer of pollen from the anther to a potential pollinator. Versatile anthers are common in wind pollinated plants such as grasses.
