Tree, shrub, woody vine, generally evergreen. Leaf: simple, alternate, occasionally ± at branch tips, often leathery, generally entire, petioled. Inflorescence: panicle, cluster, or flowers 1. Flower: generally bisexual, radial; sepals 5, free or ± fused at base; petals 5, free, erect or spreading, base generally ± adherent into tube; stamens 5; ovary superior, chambers generally 2–3, style 1, stigma generally spheric. Fruit: capsule, berry. Seed: several, often in pulp.
9 genera, ± 200 species: warm temperate, tropics, Old World, especially Australia, New Zealand, eastern Asia; some ornamental, especially Pittosporum. [Chandler et al. 2007 Aust Syst Bot 20:390–40] Sollya moved to Billardiera. —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.

Key to Pittosporaceae

Tree, shrub. Leaf: tip acute or rounded. Inflorescence: panicle, umbel-like cluster, or flowers 1, terminal or axillary. Flower: generally functionally unisexual; petals generally adherent proximally, spreading distally; anthers free; ovary chambers 2–3. Fruit: capsule, woody, 2–3 valved; pulp resinous. Seed: sticky.
± 150 species: warm parts of Australia, New Zealand, Pacific islands, eastern Asia, Africa. (Greek: pitch, seed, from resinous seed coating) Some species medicinal and poisonous; saponins in Pittosporum crassifolium.

Key to Pittosporum

Tree. Stem: < 15 m; twigs glabrous or sparsely hairy. Leaf: 7–15 cm, oblong or lance-elliptic, thin, glabrous, margin ± wavy, tip acuminate; petiole 5–25 mm. Inflorescence: umbel-like cluster, terminal. Flower: fragrant; petals 10–15 mm, white. Fruit: 10–15 mm, ± round, glabrous, 2-valved. Seed: ± red.
Uncommon but aggressively spreading. Disturbed areas, coastal scrub; < 200 m. Central Coast, South Coast, s Channel Islands; native to southeastern Australia. Nov–Jun [Online Interchange]
Unabridged note: A decline in sp. richness, cover of native herbaceous plants, shrubs documented from communities invaded by this taxon in Australia, according to Rejmanek (2012 Cal-IPC News 20(4):in press), so that its establishment in California is a serious threat to native coastal scrub in the state.
