It has smooth bark, slightly glaucous branchlets, glossy green, lance-shaped adult leaves, flower buds usually in groups of seven, white flowers and hemispherical or cup-shaped fruit.

parvifructa is a mallee or tree that typically grows to a height of 10 m (33 ft) and forms a lignotuber.

The flower buds are arranged in leaf axils in groups of seven, rarely nine on a thin, flattened, unbranched peduncle up to 8 mm (0.31 in) long.

parvifructa was first formally described in 1994 by Kevin James Rule in the journal Muelleria, from material collected near the summit of Mount William in 1970.

[3] This subspecies is only known from the Mount William Range in the Grampians National Park at altitudes of between 900 and 1,100 m (3,000 and 3,600 ft).
