Family Pittosporaceae

Trees or shrubs , evergreen , glabrous or pubescent , occasionally spiny . Leaves alternate, occasionally opposite, estipulate; leaf blade mostly leathery, margin entire, rarely dentate or lobed . 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

Trees , shrubs , or sometimes subshrubs , evergreen , pubescent or glabrous . Leavs alternate, appearing opposite or pseudoverticillate , usually clustered at branchlet apex; leaf blade leathery or sometimes membranous, margin entire, undulate-dentate, or rugose . Inflorescences terminal or axillary , umbellate , corymbose , paniculate , or a solitary flower. Flowers bisexual , rarely polygamous. Sepals 5, free , usually short and small. Petals 5, free or partly connate . Stamens 5; filament glabrous; anther dorsifixed , ± sagittate , longitudinally dehiscent . 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. Seeds usually surrounded by glutinous or greasy material .
