Source-derived summary

Eucalyptus olsenii, commonly known as the Woila gum, is a species of small tree that is endemic to a restricted area on the Southern Tablelands of New South Wales. It has smooth bark with rough bark on the lower trunk, lance-shaped to curved adult leaves, flower buds in groups of seven, white flowers and barrel-shaped or urn-shaped fruit.

Description

Eucalyptus olsenii is a tree that typically grows to a height of 10–20 mm (0.39–0.79 in) high and forms a lignotuber. It has smooth white to cream-coloured bark that is shed in ribbons, sometimes with rough, fibrous or flaky bark at the base of the trunk. Young plants and coppice regrowth have glossy green leaves that are a paler shade on the lower side, egg-shaped to lance-shaped or elliptical, 30–75 mm (1.2–3.0 in) long and 12–40 mm (0.47–1.57 in) wide. Adult leaves are the same shade of glossy green on both sides, lance-shaped to curved, 50–120 mm (2.0–4.7 in) long and 10–20 mm (0.39–0.79 in) wide on a petiole 5–15 mm (0.20–0.59 in) long. The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle 3–8 mm (0.12–0.31 in) long, the individual buds sessile or on pedicels up to 4 mm (0.16 in) long. Mature buds are oval, 10–17 mm (0.39–0.67 in) long and 6–7 mm (0.24–0.28 in) wide with a conical to beaked operculum. Flowering has been recorded in October and November and the flowers are white. The fruit is a woody, barrel-shaped or urn-shaped capsule 12–22 mm (0.47–0.87 in) long and 12–18 mm (0.47–0.71 in) wide

with the valves below the level of the rim.

Editorial summary

“Eucalyptus olsenii” enters the record as species of plant. Crown Archives preserves that source wording while asking what Eucalyptus, olsenii and species can confirm, complicate or overturn.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 271-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Eucalyptus, olsenii and species.
Editorial analysis

Why this record matters

“Eucalyptus olsenii” is worth following because a concise public description often conceals a longer documentary argument. Here, Eucalyptus, olsenii and species provides the most credible route into that argument.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 9, 2026. The linked authority identifier is Q5405660. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
