Philotheca obovatifolia, commonly known as mountain wax-flower,[2] is a species of flowering plant in the family Rutaceae and is endemic to eastern Australia.

It is a small shrub with broadly egg-shaped leaves with the narrower end toward the base and densely crowded near the ends of the glandular-warty branchlets, and cream-coloured flowers tinged with pink and arranged singly or in groups of up to five in leaf axils.

Philotheca obovatifolia is a shrub that grows to a height of about 1 m (3 ft 3 in) and has glandular-warty branchlets.

[5][6] In 2005 Paul Irwin Forster raised the subspecies to species status as Philotheca obovatifolia in the journal Austrobaileya.

Only three populations are known in a small area in Werrikimbe National Park where the main threats to the species include inappropriate fire regimes, forestry activities and disturbance by feral pigs.
