The pollen from Commelina communis is polymorphic, meaning that the pollen, and often the anthers as well, come in different colors. In this case, Commelina has yellow, blue, or brown anthers and pollens (Willner 2011). Commelina communis has sterile, or fodder pollen, as well as fertile pollen, and these different types of pollen can have different colors even on the same flower head.
