It is a small upright shrub with pink, purple or blue flowers, dark green oval shaped leaves and is endemic to Western Australia.

The pink, blue or purple flowers may have either four or five petals 1.6 cm (0.63 in) wide on a hairy pedicel.

[2] Tremandra stelligera was first formally described in 1824 by Augustin Pyramus de Candolle from an unpublished description by Robert Brown and de Candolle's description was published in Prodromus Systematis Naturalis Regni Vegetabilis.

[3][4] The specific epithet (stelligera) is derived from the Latin stelliger for "star-bearing" and "starry", referring to the stellate hairs.

[5][6] The species is found in the south-west corner of Western Australia in a variety of habitats on loam and sandy soils.
