Family Name: | Pittosporaceae |
Pittosporum ferrugineum is a small to medium sized tree that can grow to 20 m tall. It has aromatic, narrowly elliptic to obovate leaves with a tapering pointed tip. Flowers are fragrant, cream coloured, 5-petalled, clustered in an inflorescence near the ends of branches, amongst the foliage. The fruit is a capsule with wide, lobed to fluted base that turns orange and spilt open upon maturity to reveal brick red seeds coated in resins.
