Physical Description

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.

About 150 species: Bangladesh, Bhutan, China, India, Indonesia, Japan, Korea, Laos, Malaysia, Myanmar, Nepal, Pakistan, Papua New Guinea, Philippines, Sikkim, Singapore, Sri Lanka, Thailand, Vietnam; tropical and S Africa (including Madagascar), SW Asia (Yemen), Atlantic Islands (Madeira), Australia, Indian Ocean Islands (Mascarenes, Seychelles), Pacific Islands; 46 species (33 endemic) in China.^[2]
