Philotheca tomentella is a species of flowering plant in the family Rutaceae and is endemic to the south-west of Western Australia. It is an undershrub with small club-shaped to cylindrical leaves and white flowers with a pale red central stripe, arranged singly or in groups of up to four on the ends of branchlets.

Description
Philotheca tomentella is an undershrub that typically grows to a height of 0.3-1.0 m and has slightly glandular-warty branchlets. The leaves are club-shaped to more or less cylindrical, 2–3 mm long, flat on the upper surface and rounded on the lower. The flowers are arranged singly or in groups of up to four on the ends of branchlets, each flower on a pedicel 1.5–3 mm long. The five sepals are broadly triangular to more or less round, about 1 mm long with a tiny black tip. The five petals are egg-shaped and white with a pale red central stripe and 4–5.5 mm long. The ten stamens are free from each other and the anthers have a prominent white appendage. Flowering occurs from August to October and the fruit is about 3.5 mm long.
