Genus: PittosporumView DescriptionDichotomous Key


Habit: 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.
Etymology: (Greek: pitch, seed, from resinous seed coating) Note: Some species medicinal and poisonous; saponins in Pittosporum crassifolium.
Pittosporum undulatum Vent.
NATURALIZED
Habit: 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.
Ecology: Uncommon but aggressively spreading. Disturbed areas, coastal scrub; Elevation: < 200 m. Bioregional Distribution: CCo, SCo, s ChI; Distribution Outside California: native to southeastern Australia. Flowering Time: Nov--Jun
Unabridged Note: A decline in sp. richness, cover of native herbaceous pls, 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.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
