Eucalyptus sideroxylon
species of plant
Eucalyptus sideroxylon, commonly known as mugga ironbark, or red ironbark is a small to medium-sized tree that is endemic to eastern Australia. It has dark, deeply furrowed ironbark, lance-shaped adult leaves, flower buds in groups of seven, white, red, pink or creamy yellow flowers and cup-shaped to shortened spherical fruit.
Description
Eucalyptus sideroxylon is a tree that typically grows to a height of 25–35 m (82–115 ft) and forms a lignotuber. The bark is dark grey to black, deeply furrowed ironbark on the trunk and larger branches, smooth white to grey on the thinnest branches. Young plants and coppice regrowth have lance-shaped to oblong or linear leaves that are 30–110 mm (1.2–4.3 in) long and 5–35 mm (0.20–1.38 in) wide. Adult leaves are lance-shaped, the same shade of green on both sides, 50–140 mm (2.0–5.5 in) long and 10–40 mm (0.39–1.57 in) wide tapering to a petiole 5–25 mm (0.20–0.98 in) long. The flower buds are arranged in leaf axils on an unbranched peduncle 7–29 mm (0.28–1.14 in) long, the individual buds on pedicels 3–15 mm (0.12–0.59 in) long. Mature buds are oval or diamond-shaped, 6–15 mm (0.24–0.59 in) long and 4–6 mm (0.16–0.24 in) wide with a conical to beaked operculum. Flowering occurs from April to December and the flowers are white, red, pink or creamy yellow. The fruit is a woody cup-shaped to shortened spherical capsule 5–11 mm (0.20–0.43 in) long and 5–10 mm (0.20–0.39 in) wide with the valves below the level of the rim.
This brief starts where responsible research should: with the source description of “Eucalyptus sideroxylon” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jun 19, 2026. The linked authority identifier is Q2667019. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
