Quercus robur subsp. pedunculiflora
subspecies of plant
Quercus robur subsp. pedunculiflora, or Quercus pedunculiflora, the grayish oak, is a subspecies of flowering plant in the beech and oak family, Fagaceae. Its a large tree, native to South-Eastern Europe, in the Balkan Peninsula and Peloponnesos, through Thrace and Eastern Anatolia, and the Caucasus. It can be found in deciduous forest, flood plains and steppes, up to 1800 m above sea level. It is a drought adapted species, being able to tolerate extreme heat, and for this reason Q. robur subsp. pedunculiflora may become a very important tree species for forestry, particularly in the context of global climate change.
Taxonomy
Quercus robur subsp. pedunculiflora is a species controversial in taxonomy. Some authors consider it as only a race of Quercus robur, the differences from the common subspecies being the result of an adaptation to drier climates and probable intermixture from other species (Quercus pubescens and Quercus petraea in the north of its range and Quercus infectoria in the south). This theory agrees with authors who noticed introgression of Quercus robur with more drought adapted oak species (Kleinschmit 1993), which took place at the time of the migration of Quercus robur into the Quercus pubescens area and vice versa.
“Quercus robur subsp. pedunculiflora” enters the record as subspecies of plant. Crown Archives preserves that source wording while asking what Quercus, robur and subsp can confirm, complicate or overturn.
Why this record matters
“Quercus robur subsp. pedunculiflora” is worth following because a concise public description often conceals a longer documentary argument. Here, Quercus, robur and subsp provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 19, 2025. The linked authority identifier is Q21384335. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1800 and 1993.
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.
