Quercus robur, the pedunculate oak or English oak, [3] [4] is a species of flowering plant in the beech and oak family, Fagaceae. It is a large tree, native to most of Europe and western Asia , and is widely cultivated in other temperate regions.
Molecular techniques for phylogenetic analysis show that the genus Quercus consisted of Old World and New World clades. [20] [21] [22] The entire genome of Quercus robur (the pedunculate oak) has been sequenced, [23] revealing an array of mutations that may underlie the evolution of longevity and disease resistance in oaks.

NVC community W10 (Quercus robur - Pteridium aquilinum - Rubus fruticosus woodland) is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group. This is a widely distributed community, except in Scotland.
The genus Quercus contains about 500 known species, plus about 180 hybrids between them. [1] The genus, as is the case with many large genera, is divided into subgenera and sections. Traditionally, the genus Quercus was divided into the two subgenera Cyclobalanopsis, the ring-cupped oaks, and Quercus, which included

Roburin A is a tannin found in oak wood (Quercus robur and Quercus petraea [1] or Quercus alba [2]) or oak cork (Quercus suber [3]).. It is a dimeric compound, composed of two vescalagin subunits probably linked through an ether bond between the diphenoyl group (hexahydroxydiphenic acid or HHDP) of one subunit and the triphenoyl moiety (nonahydroxytriphenic acid) of the other one.
