Source-derived summary

Eucalyptus redunca, commonly known as black marlock, is a species of mallee or a shrub that is endemic to Western Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of between nine and fifteen, lemon-coloured flowers and barrel-shaped fruit.

Description

Eucalyptus redunca is a mallee that typically grows to a height of 1–4.5 m (3 ft 3 in – 14 ft 9 in) and forms a lignotuber. It has grey and pale brown bark that is shed in short ribbons. The adult leaves are narrow-lance-shaped to lance-shaped, 50–75 mm (2.0–3.0 in) long and 9–25 mm (0.35–0.98 in) wide tapering to a petiole 8–15 mm (0.31–0.59 in) long. The flower buds are arranged in leaf axils in groups of between nine and fifteen on an unbranched peduncle 8–15 mm (0.31–0.59 in) long, the individual buds on pedicels 3–5 mm (0.12–0.20 in) long. Mature buds are an elongated spindle shape, 16–26 mm (0.63–1.02 in) long and 3–4 mm (0.12–0.16 in) wide with a conical to horn-shaped operculum that is two or three times as long as the floral cup. Flowering occurs from July to October or November and the flowers are lemon-coloured. The fruit is a woody, barrel-shaped capsule 7–11 mm (0.28–0.43 in) long and 5–8 mm (0.20–0.31 in) wide with the valves near rim level.

Taxonomy and naming

Eucalyptus redunca was first formally described in 1844 by Johannes Conrad Schauer in 1844 in Johann Georg Christian Lehmann's book Plantae Preissianae.

Editorial summary

Begin with the source’s own compact description: “Eucalyptus redunca” is species of eucalyptus endemic to Western Australia. The dossier treats that line as a proposition to test through Eucalyptus, redunca and species, not as a finished interpretation.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1844—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Eucalyptus, redunca and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of eucalyptus endemic to Western Australia” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

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 11, 2026. The linked authority identifier is Q5405690. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1844.

Critical limits

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.
