 Current def'n:  A plant organ that produces and contains one or more gametes that are located in it and is part of a whole plant  in the gametophytic phase.
-Note: in some green algae such as Ulva, the gametangia are single cells (Raven et al, (1992) Biology of plants, 5th ed.) so can this still be a plant organ? Also the gametes are not always contained in the gametangium.

 Raven definition: "A cell or organ in which gametes are formed."  In this case we would have to make it a plant structure.
