Flowers usually bisexual , sometimes polygamous, actinomorphic , rarely zygomorphic, usually 5-merous (except ovary) . Sepals usually free or slightly connate . Petals free or connate, white, yellow, blue, or red. Stamens opposite sepals; filament filiform ; anther basifixed or dorsifixed , 2-loculed, dehiscing longitudinally or by pores . Ovary superior, of 2 or 3( 5) carpels, usually 1-loculed or incompletely 2 5-loculed; ovules numerous , anatropous ; placentation parietal , axile , or basilar. Style short, simple or 2 5-lobed, persistent or deciduous. Fruit a capsule dehiscing by adaxial suture, or a berry. Seeds numerous; testa thin; endosperm well developed; embryo small.
