Description

Eucalyptus suffulgens is a tree that typically grows to a height of 25 m (82 ft) and forms a lignotuber. It has dark grey to black ironbark on the trunk and larger branches, the thinner branches often with smooth bark. Young plants and coppice regrowth have glossy green, lance-shaped leaves that are 70–130 mm (2.8–5.1 in) long and 6–25 mm (0.24–0.98 in) wide. Adult leaves are the same shade of glossy green on both sides, lance-shaped, 80–160 mm (3.1–6.3 in) long and 15–25 mm (0.59–0.98 in) wide tapering to a petiole 8–20 mm (0.31–0.79 in) long. The flower buds are arranged on the ends of branchlets in groups of seven on a branched peduncle 10–20 mm (0.39–0.79 in) long, the individual buds on pedicels 3–10 mm (0.12–0.39 in) long. Mature buds are oval to pear-shaped, 7–10 mm (0.28–0.39 in) long and 4–5 mm (0.16–0.20 in) wide with a conical operculum that is shorter and narrower than the floral cup. Flowering occurs from April to September and the flowers are white. The fruit is a woody, barrel-shaped capsule 7–13 mm (0.28–0.51 in) long and 5–10 mm (0.20–0.39 in) wide with the valves below rim level.[2][3]

Taxonomy and naming

Eucalyptus suffulgens was first formally described in 1991 by Ken Hill and Lawrie Johnson in the journal Telopea from specimens collected by Johnson near Biloela in 1971.[3][4] The specific epithet (suffulgens) is from the Latin sub- meaning "somewhat" and fulgens meaning "shining", referring to the leaves of the species.[3]

Distribution and habitat

This ironbark is locally abundant on shallow soil over sandstone on ranges and escarpments in the central ranges of Queensland, including the Blackdown Tableland.[2][3]

Conservation stutus

This eucalypt is classified as "least concern" under the Queensland Government Nature Conservation Act 1992.[5]
