Platysace ericoides is a semi-prostrate to weakly erect, open shrub that typically grows to a height of 10–50 cm (3.9–19.7 in) and has scaly or hairy branches.

[2][3] This species was first formally described in 1827 by Kurt Polycarp Joachim Sprengel who gave it the name Trachymene ericoides from an unpublished description by Franz Sieber.

[4][5] In 1939, Cecil Norman transferred the species to Platysace as P. ericoides in the Journal of Botany, British and Foreign.

[7] Platysace ericoides grows in heath and woodland on sandy soil from Mittagong in New South Wales to south-east Queensland and between Moe and Orbost in Victoria.
