Pittosporum bicolor, commonly known as cheesewood or banyalla, is a flowering shrub or small tree of the family Pittosporaceae, and is native to south eastern Australia.

[1] Pittosporum bicolor was first described by William Jackson Hooker in 1834, in his paper Contributions Towards a Flora of Van Deimen's Land, which was published in the Journal of Botany 1[2].

[3] The flowers are bell shaped,[4] and the perianth consists of 5 sepals, which are 5-6mm long[3] and slightly curve inwards at the apex, the lower surface is coated in fine white hairs.

[3][4][5] Each flower typically houses 5 stamens and a single pistil,[5] the ovary is superior and heavily coated in fine hairs.

The fruit is a globose woody capsule,[3] it is covered in fine white hairs, and varies in colour from orange to brown as it matures.

It prefers to grow in moist, well drained soils,[3][4] and does not typically occur at altitudes greater than 1,000 metres above sea level.

[3][4] It is not uncommon for Pittosporum bicolor to occur as an epiphyte on soft tree fern species, such as Dicksonia antarctica,[7] this is possibly an adaptation to avoid seedlings being consumed by browsing mammals.
