不育雄蕊 Staminodes
不育雄蕊泛指不育或發育不全的雄蕊，不能生產花粉。它們雖然具有雄蕊形態，但通常不太明顯，一般出現於花朵的內輪。有時較長的不育雄蕊能伸出花冠。
Staminodes are often sterile or abortive stamens, which do not produce pollen grains. They are stamen-like but frequently inconspicuous and usually occurring at the inner whorl of the flower. They are also sometimes long enough to protrude from the corolla.
