It is a shrub or small tree with long, narrow leaves that are a darker green on their upper surface than the lower.

As its common name suggests, this plant is restricted to higher places, around 1,000 metres (3,000 ft) above sea level.

[1][2] The flowers are arranged in groups of 3 to 8 on a short stalk in the axils of the leaves and have 5 sepals and 5 white petals joined at their base to form a tube.

The fruits are roughly oval to spherical in shape and are smooth, white or cream coloured tinged with pink.

[1][2] Myoporum betcheanum was first formally described in 1969 by Lindsay Stuart Smith in Contributions from the Queensland Herbarium from a specimen collected at Cunninghams Gap.
