The Yanchep Mallee is a small, multi-stemmed mallee tree growing to 4 metres in height. The bark is smooth, and grey to pale copper in colour. Adult leaves are thick, glossy green and alternate. They are 7.3-12 cm long, 1.2-3 cm wide and are broadly lanceolate. Leaf stems are 1.8-2.5 cm long. Juvenile leaves are 4-7 cm long and 3-5.5 cm wide. Comparative to adult leaves, the base, and sometimes tip, of the juvenile leaf is rounded. Juvenile leaves are opposite for a few nodes of each branch and then alternate.

The distribution of this species overlaps with the Sedgelands in Holocene dune swales of the southern Swan Coastal Plain EPBC Act listed threatened ecological community Threats The main identified threats to Yanchep Mallee are mining activities; inappropriate fire regimes; grazing and weeds.
Weeds have the potential to alter fire and grazing patterns and suppress early plant growth by competing for soil moisture; nutrients and light (DEC; 2008).
