Eucalyptus pachyloma

The mallee typically grows to a height of 1 to 4 m (3 ft 3 in to 13 ft 1 in) and has smooth grey-brown to green coloured bark and forms a lignotuber. The concolorous, glossy, green adult leaves are erect and alternately arranged. The leaf blade is usually a lanceolate shape with a length of 5.8 to 10.8 cm (2.3 to 4.3 in) and a width of 0.7 to 1.8 cm (0.28 to 0.71 in) with a pointed apex and a base that tapers to the petiole. It blooms between October and March producing white to cream coloured flowers. Each axillary unbranched inflorescence has umbels containing seven to thirteen buds. The ovoid to globular shaped mature buds have a length of 0.7 to 1.0 cm (0.28 to 0.39 in) and a width of 0.6 to 0.9 cm (0.24 to 0.35 in) with no scar. The single operculum has a conical to rounded with irregularly flexed stamens. The fruit that form later are broadly cupular to obconical in shape with a length of 0.7 to 1.1 cm (0.28 to 0.43 in) and a width of 1.2 to 1.7 cm (0.47 to 0.67 in) with a raised and convex disc and three valves at rim level. The brown seeds within are pyramidal to semi-circular in shape and 2.5 to 3.5 mm (0.098 to 0.138 in) long.
