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.
