It is a small shrub with compact, narrow, more or less erect, sharply-pointed leaves, white or yellowish flowers and more or less spherical, red drupes.

The flowers are arranged singly in leaf axils, with eight to ten overlapping green to cream-coloured bracts up to 3.9–6.7 mm (0.15–0.26 in) long.

Flowering occurs from March to August, and the fruit is a reddish-brown, elliptic drupe 4.8–5.1 mm (0.19–0.20 in) long and smooth.

[2][3][4] Melichrus gibberagee was first formally described in 2020 by Helen T. Kennedy and Jeremy James Bruhl in the journal Telopea from an unpublished description by John Beaumont Williams.

[3] This species of Melichrus grows in tall open forest on gentle slopes in the Gibberagee area, about 50 km (31 mi) south of Casino.
