It is an erect, straggling shrub with lance-shaped leaves with a sharp point on the tip, and white flowers arranged in pairs in leaf axils.

Styphelia conostephioides is an erect, straggling shrub that typically grows up to about 30 cm (12 in) high and wide, its young branchlets sometimes softly-hairy.

The leaves are directed upwards or spreading, lance-shaped, 6–13 mm (0.24–0.51 in) long, tapering to a sharp, rigid point on the tip and finely striated.

[2] This species was first described in 1839 by Augustin Pyramus de Candolle who gave it the name Leucopogon conostephioides in his Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected by James Drummond near the Swan River Colony.

[5][6] Styphelia conostephioides is found from near Lesueur National Park to Dunsborough and inland to Boyup Brook in the Geraldton Sandplains, Jarrah Forest, Mallee and Swan Coastal Plain bioregions of south-western Western Australia.
