General description

This is a medium to tall evergreen tree with a moderately straight trunk that is distinctively mottled and greenish with peeling bark. With low branches, it often holds foliage close to the ground and has a very wide and bushy crown. The flowers are held in unusually large clusters. Height 25m Spread 15m.

Natural distribution and habitat  

The species is native to a few sites with the largest in the Northern Tablelands in New South Wales, Australia. It grows on broad, flat topped ridges, on mountain slopes and below sandstone outcrops on lower valley slopes in either mixed wet sclerophyll forest or as small, almost pure stands.

Conservation status

It is a rare species that is not plentiful in any of the areas where it grows. It is being conserved in a number of flora reserves within Carrai National Park in northern New South Wales.

Planting pattern

Planted in irregular lines with wider spacings near the boundary fence.

Uses

As the heartwood is brittle, it has possibly only been used as firewood.
