Source-derived summary

Corylus chinensis, common names Chinese filbert and Chinese hazel, is a deciduous shrub or tree native to south-central China. This tree is considered vulnerable due to its rarity.

Description

Corylus chinensis is a deciduous tree which grows up to 20 metres tall. It has gray-brown, fissured bark, with mottled streaks. The branchlets are a purplish-brown colour, and are slender and sparsely villous. The leaves range from ovate to obovate-elliptic and have a doubly serrated, irregular margin. It flowers from April to May, and fruits ripen in September and October.

Distribution and habitat

Corylus chinensis is native to Henan, Hubei, Hunan, Shaanxi, Sichuan, and Yunnan provinces of south-central China. It grows on moist slopes of temperate and subtropical broadleaf forests from 1,200 to 3,500 metres elevation. It prefers sunny locations and typically grows in the forest canopy or forest edges on deep, fertile, well-drained neutral or acidic soils.

Editorial summary

Begin with the source’s own compact description: “Corylus chinensis” is species of plant. The dossier treats that line as a proposition to test through Corylus, chinensis and species, not as a finished interpretation.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 147-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, Corylus, chinensis 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 Aug 14, 2026. The linked authority identifier is Q1073905. 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.
