Inflorescences umbellate , corymbose , paniculate , or a solitary flower, bracteate and bracteolate . 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.

Nine genera and ca. 250 species: tropical and subtropical regions of Africa, Asia, Australia, and Pacific Islands, especially Australia; one genus and 46 species (33 endemic) in China.[1]

Genus Pittosporum

Ovary superior, usually stipitate , of 2 or 3(-5) carpels, 1-loculed or incompletely 2-5-loculed, pubescent or glabrous; ovules usually numerous , sometimes 1-4; placentas parietal and equal in number to carpels, or basilar owing to reduction of ovules. Style short, simple or 2-5-lobed, usually persistent . Capsule ellipsoid or globose , sometimes compressed , dehiscing by 2-5 valves ; pericarp woody or leathery, usually with horizontal striae adaxially.
