为了验证花器官大小相关性受自然选择调控的假说，本文对雌雄同株的Commelina communis各花器官的大小进行了测定。比较了完全花和不育雌蕊雄蕊花6个花器官大小的相关性。完美花的柱头长雄蕊花药相关性最强，而雄蕊花的相关性较弱。这表明，可育柱头的位置可能已经进化到最大限度地从传粉者那里接收来自相同高度的l -花药的花粉粒。
The sizes of various floral organs of andromonoecious Commelina communis were measured to test the hypothesis that size correlations among floral organs are regulated by natural selection. Size correlations among six floral organs in both perfect flowers and staminate flowers with sterile pistils were compared. The stigma-long stamen anther (Lanther) correlation for perfect flowers was the strongest of all C. communis floral correlations, whereas this correlation was weak in staminate flowers. This suggests that the position of fertile stigmas may have evolved to maximize receipt from pollinators of pollen grains from L-anthers of the same height in perfect flowers.
