Source-derived summary

Myoporum laetum, commonly known as ngaio ( NY-oh, Māori: [ˈŋaio]) or mousehole tree, is a species of flowering plant in the family Scrophulariaceae and is endemic to New Zealand. It is a fast growing shrub or small tree with lance-shaped leaves, the edges with small serrations, and white flowers with small purple spots and 4 stamens.

Description

Ngaio is a fast-growing evergreen shrub or small tree that sometimes grows to a height of 10 metres (30 ft) with a trunk up to 0.3 metres (1 ft) in diameter, or spreads to as much as 4 metres (10 ft). It often appears dome-shaped at first but as it gets older, distorts as branches break off. The bark on older specimens is thick, corky and furrowed. The leaves are lance-shaped, usually 52–125 millimetres (2–5 in) long, 15–30 millimetres (0.6–1 in) wide, have many translucent dots in the leaves and edges that have small serrations in approximately the outer half.

The flowers are white with purple spots and are borne in groups of 2 to 6 on stalks 7–15 millimetres (0.3–0.6 in) long. There are 5 egg-shaped, pointed sepals and 5 petals joined at their bases to form a bell-shaped tube 3.5–4.5 millimetres (0.1–0.2 in) long. The petal lobes are 4.5–5.5 millimetres (0.18–0.22 in) long making the flower diameter 15–20 millimetres (0.6–0.8 in). There are four stamens that extend slightly beyond the petal tube and the ovary is superior with 2 locules.

Editorial summary

“Myoporum laetum” enters the record as species of plant. Crown Archives preserves that source wording while asking what Myoporum, laetum 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 239-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 Myoporum, laetum and species.
Editorial analysis

Why this record matters

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

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 Jul 5, 2026. The linked authority identifier is Q153042. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
