Yarra Gum

Eucalyptus yarraensis is a tree that typically grows to a height of 15–20 m (49–66 ft) and forms a lignotuber. It has rough, fibrous, brown or greyish bark on the trunk and larger branches, smooth white to cream-coloured bark above. Young plants and coppice regrowth have glossy green, elliptical to egg-shaped leaves that are 25–63 mm (0.98–2.48 in) long and 20–43 mm (0.79–1.69 in) wide. Adult leaves are arranged alternately, the same shade of glossy green on both sides, lance-shaped to elliptical or egg-shaped, 60–135 mm (2.4–5.3 in) long and 17–40 mm (0.67–1.57 in) wide, tapering to a petiole 10–28 mm (0.39–1.10 in) long. The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle 4–15 mm (0.16–0.59 in) long, the individual buds on pedicels 2–3 mm (0.079–0.118 in) long. Mature buds are oval to diamond-shaped, 3–6 mm (0.12–0.24 in) long and 3–4 mm (0.12–0.16 in) wide with a conical or beaked operculum that is about the same length as the floral cup. Flowering occurs from September to December and the flowers are white. The fruit is a woody, conical capsule 3–5 mm (0.12–0.20 in) long and 4–5 mm (0.16–0.20 in) wide with the valves near rim level.

Yarra gum grows in valleys and nearby slopes in open woodland, now mostly cleared for agricultural use. It is found between Melbourne, Daylesford and Ararat.
