Pittosporum virgatum is an uncommon threatened northland species of Pittosporum found only in Northland, Great Barrier Island and the Coromandel Peninsula. 
Pittosporum virgatum grows up to 6 m tall with slender trunks whose bark is dark brown to black.
The thin leaves are a shiny green with margins that are slightly undated (wavy). Terminal red/pink/purple flowers (5-6 mm) appear in early spring and these are followed by a single capsule (c. 1cm) which develops from mid-summer on to a black two-valved capsule which contains sticky seeds.
