Description

Eucalyptus melanoleuca is a tree that typically grows to a height of 30 m (98 ft) and forms a lignotuber. It has rough black bark on the trunk and larger branches, smooth white bark above. Young plants and coppice regrowth have egg-shaped leaves 45–85 mm (1.8–3.3 in) long and 20–40 mm (0.79–1.57 in) wide on a short petiole. Adult leaves are the same shade of glossy green on both sides, lance-shaped, 85–145 mm (3.3–5.7 in) long and 15–35 mm (0.59–1.38 in) wide, tapering to a petiole 12–20 mm (0.47–0.79 in) long. The flower buds are arranged in leaf axils and on the ends of branchlets on a branching peduncle, each branch with groups of seven buds. The peduncle is 5–15 mm (0.20–0.59 in) long with each bud on a pedicel 2–7 mm (0.079–0.276 in) long. Mature buds are oval to pear-shaped, 5–9 mm (0.20–0.35 in) long and 3–6 mm (0.12–0.24 in) wide with a conical operculum that is narrower and shorter that the floral cup. Flowering mainly occurs between June and September and the flowers are white. The fruit is a woody, barrel-shaped to cup-shaped or hemispherical capsule 4–7 mm (0.16–0.28 in) long and wide, with the valves below the level of the fruit. [4] [5]

Taxonomy and naming

Eucalyptus melanoleuca was first formally described by Stanley Thatcher Blake in the journal Austrobaileya from a specimen he collected near Yarraman. [6] [7] The specific epithet (melanoleuca) refers to the strongly contrasted black and white trunk. [7]

Distribution and habitat

Yarraman ironbark grows in open forest and on the edges of rainforest between the Blackdown Tableland and Yarraman. [5]

Conservation status

This eucalypt is classed as "least concern" under the Queensland Government Nature Conservation Act 1992 . [3]
