Commelinaceae -- comments
Genera: Tradescantia (spiderwort), Zebrina (wandering jew), Commelina (dayflower), Rhoeo (boat-flower, oyster-plant), Gibasis (bride’s veil), Geogenanthus (the seersucker plant), Setcreasea (purple heart), Callisia.
Comments: Only important as an ornamental, this family is nonetheless a hardy houseplant, and in some mild areas, has escaped to become a weed.
The flowers in this family are insect pollinated, but do not produce nectar. The pollen is the reward, and since a lot of pollen has to be produced to supply enough for both pollination and the pollinator, it is believed that this family may be part of a trend that culminated in wind-pollination.
