Epacris sprengelioides is an erect shrub that typically grows to a height of up to 150 cm (59 in), its branchlets covered with shaggy hairs.

Flowering occurs from September to February and the fruit is a capsule about 1.8 mm (0.071 in) long.

[2][3][4][5] This species was first formally described in 1899 by Joseph Maiden and Ernst Betche who gave it the name Rupicola sprengelioides in the Proceedings of the Linnean Society of New South Wales, from specimens collected in 1898 at the southern edge of the Kings Tableland in the Blue Mountains.

[6][7] In 2015, Elizabeth Brown changed the name to Epacris sprengelioides in Australian Systematic Botany.

[8] Epacris sprengelioides grows on sandstone ledges, cliff faces and rocky ground in the Burragorang Valley section of the Blue Mountains in eastern New South Wales.
