Myoporum betcheanum, commonly known as mountain boobialla is a plant in the figwort family, Scrophulariaceae. It is a shrub or small tree with long, narrow leaves that are a darker green on their upper surface than the lower. Its flowers have five white petals and are arranged in small groups in the leaf axils. The fruits which follow are more or less spherical, soft, cream coloured drupes. As its common name suggests, this plant is restricted to higher places, around 1,000 metres (3,000 ft) above sea level. It occurs in the McPherson Range and nearby mountains of New South Wales and Queensland.
