Eucalyptus costuligera is a species of small tree that is endemic to the Kimberley region of Western Australia. It has short-fibrous or flaky bark on the trunk and branches, bluish, lance-shaped adult leaves, club-shaped flower buds in branched or unbranched inflorescences with the buds in groups of up to seven, creamy-white flowers and conical, cup-shaped or pear-shaped fruit.

Description

Eucalyptus costuligera is a tree that typically grows to a height of 5–10 m (16–33 ft) and has persistent pale grey, fibrous or flaky "box"-type bark on the trunk and branches. The adult leaves are arranged alternately, the same grey-green or bluish colour on both sides, lance-shaped, 70–150 mm (2.8–5.9 in) long and 17–30 mm (0.67–1.18 in) wide on a channelled or flattened

capsule 6–8 mm (0.24–0.31 in) long and 5–7 mm (0.20–0.28 in) wide with fine ribs along the sides and the valves enclosed below the rim.[3][4][1]

Taxonomy and naming

Eucalyptus costuligera was first formally described in 2000 by Lawrie Johnson and Ken Hill from a specimen collected 60 km (37 mi) from the Derby-Gibb River Road, on the road to Wyndham.[4][5] The specific epithet (costuligera) is derived from the Latin costula, meaning "a costule or rib" (strictly the midrib of a fern frond) and -ger meaning "-bearing", referring to the finely ribbed fruit.[4][6]

Distribution and habitat

This eucalypt has a limited range but is abundant in a small area in the central Kimberley region of Western Australia, growing in savannah woodland in sandy to loamy soils over laterite.[1][4]

Conservation status

This species is classified as is classified as "

Department of Parks and Wildlife[1] meaning that it is known from only one or a few locations which are potentially at risk.[7]
