Source-derived summary

Melaleuca megalongensis, commonly known as Megalong Valley bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales. (Some Australian state herbaria use the name Callistemon megalongensis). It is a shrub similar to Melaleuca citrina (Callistemon citrinus) which occurs in the same area and is difficult to distinguish from it, except when in flower.

Description

Melaleuca megalongensis is a shrub growing to 5 m (20 ft) tall with soft, flaking or peeling bark. Its leaves are arranged alternately and are 35–55 mm (1–2 in) long, 3.5–5 mm (0.1–0.2 in) wide, flat, narrow elliptic to narrow egg-shaped with the narrow end towards the base. There is a mid-vein and 15 to 24 lateral veins. The leaves usually have some thickening at the mid-vein and margins.

The flowers are arranged in spikes on the ends of branches which continue to grow after flowering and are 30–40 mm (1–2 in) in diameter with 25 to 60 individual flowers. The petals are 3.0–3.7 mm (0.12–0.15 in) long and fall off as the flower ages and there are 45-50 stamens in each flower. The filaments of the stamens are pink with a dark red anther.

Editorial summary

Begin with the source’s own compact description: “Melaleuca megalongensis” is species of plant. The dossier treats that line as a proposition to test through Melaleuca, megalongensis 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 195-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, Melaleuca, megalongensis 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

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 May 24, 2026. The linked authority identifier is Q17596320. 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 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.
