Source-derived summary

Eucalyptus percostata, commonly known as the rib-capped mallee or Devils peak mallee, is a species of mallee that is endemic to South Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of seven, creamy white flowers and cup-shaped to conical fruit. It is only known from a few locations in the Flinders Ranges.

Description

Eucalyptus percostata is a mallee that typically grows to a height of 3–10 m (9.8–32.8 ft) and forms a lignotuber. It has smooth whitish bark that is coppery when new. Young plants and coppice regrowth have broadly lance-shaped to broadly egg-shaped leaves that are 50–100 mm (2.0–3.9 in) long and 30–60 mm (1.2–2.4 in) wide. Adult leaves are the same shade of green on both sides, lance-shaped, 70–120 mm (2.8–4.7 in) long and 12–25 mm (0.47–0.98 in) wide tapering to a petiole 10–22 mm (0.39–0.87 in) long. The flower buds are arranged in leaf axils on a peduncle 8–20 mm (0.31–0.79 in) long, the individual buds sessile or on pedicels up to 2 mm (0.079 in) long. Mature buds are pear-shaped, 8–12 mm (0.31–0.47 in) long and 6–7 mm (0.24–0.28 in) wide with a conspicuously ribbed, rounded to conical operculum. Flowering from May to September and the flowers are creamy white.

Editorial summary

Begin with the source’s own compact description: “Eucalyptus percostata” is species of plant. The dossier treats that line as a proposition to test through Eucalyptus, percostata 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 208-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Eucalyptus, percostata and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of plant” 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

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 9, 2026. The linked authority identifier is Q15354208. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
