Description

Eucalyptus melanophitra is a mallet that typically grows to a height of 4–7 m (13–23 ft) but does not form a lignotuber. It has rough, flaky grey bark on part or all of the trunk, smooth greyish bark above. The adult leaves are narrow lance-shaped, 55–95 mm (2.2–3.7 in) long and 9–15 mm (0.35–0.59 in) wide on a petiole 5–13 mm (0.20–0.51 in) long. The flower buds are arranged in leaf axils in groups of nine or eleven on an unbranched peduncle 7–15 mm (0.28–0.59 in) long, the individual buds on pedicels about 3 mm (0.12 in) long. Mature buds are spindle-shaped, 13–15 mm (0.51–0.59 in) long and about 3 mm (0.12 in) wide with a conical operculum about twice as long as the floral cup. Flowering occurs between February and April and the flowers are pale yellow. The fruit is a woody, cylindrical to barrel-shaped capsule 6–7 mm (0.24–0.28 in) long and 4–5 mm (0.16–0.20 in) wide with the valves near rim level.[2][3][4]

Taxonomy and naming

Eucalyptus melanophitra was first formally described in 1991 by Ian Brooker and Stephen Hopper in the journal Nuytsia from a specimen collected by Brooker in 1985. The specific epithet (melanophitra) means "black bole" or "black trunk".[4][5]

Distribution and habit

This eucalypt is found on stony breakaways in small areas near the Pallinup River and the Corackerup Nature Reserve, where it grows in skeletal soils over laterite.[2][4]

Conservation status

Eucalyptus melanophitra is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife,[2] meaning that is rare or near threatened.[6]
