Source-derived summary

Quercus pubescens (synonyms virgiliana), commonly known as the downy oak, pubescent oak or Italian oak, is a species of white oak (genus Quercus sect. Quercus) native to southern Europe and southwest Asia. It is found from northern Spain (Pyrenees) and France in the West to Turkey and the Caucasus in the East.

Description

Quercus pubescens is a medium-sized deciduous tree growing up to 20 metres (66 feet). Forest-grown trees grow tall, while open-growing trees develop a very broad and irregular crown. They are long-lived, to several hundred years, and eventually grow into very stout trees with trunks up to 2 m (6+1⁄2 ft) in diameter. Open-grown trees frequently develop several trunks. The bark is very rough, light gray and divided into small flakes. Large trees develop very thick whitish bark cracked into deep furrows, similar to the pedunculate oak but lighter in colour.

The twigs are light purple or whitish, with tomentum.

Editorial summary

“Quercus pubescens” enters the record as species of plant. Crown Archives preserves that source wording while asking what Quercus, pubescens 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 152-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 Quercus, pubescens and species.
Editorial analysis

Why this record matters

“Quercus pubescens” is worth following because a concise public description often conceals a longer documentary argument. Here, Quercus, pubescens 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 10, 2026. The linked authority identifier is Q161415. The Library of Congress control number is sh88023054. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.

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.
