Quercus robur (from the Latin quercus, "oak" + robur derived from a word meaning robust, strong) was named by Carl Linnaeus in Species Plantarum (1753). [11] [12] It is the type species of the genus and classified in the white oak section (Quercus section Quercus). [13] It has numerous common names, including "common oak", "European oak" and ...
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. [24]
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
Quercus × rosacea (or Quercus rosacea) (or Devony Oak), is a naturally occurring hybrid species of oak native to Europe. They are the offspring of sessile oak, Quercus petraea, and common oak, Quercus robur, found where their ranges overlap. As hybrids, they are morphologically variable, but in general their traits appear intermediate to those ...
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.
The Grave Oak (in German: Grabeiche, also known as the burial oak, Thümmel oak or "thousand-year-old oak ") is a striking old specimen of the pedunculate oak (Quercus robur) in Nöbdenitz in Thuringia. There is a grave site in the tree's hollow trunk. According to the Guinness Book of Records, it is the oldest pedunculate oak in Europe ...
The Rumskulla oak, also known as the Kvill oak, is an oak tree (Quercus robur) [1] [2] near Norra Kvill National Park in Rumskulla socken, Vimmerby, Kalmar County, Småland, Sweden. It is the oldest oak in Sweden and one of the largest trees in Scandinavia, and was first described in 1772.
The Sobieski Oak (Polish: Dąb Sobieskiego) is an over 400-year-old specimen of pedunculate oak (Quercus robur) located within the Łężczok nature reserve, within the administrative boundaries of Racibórz.
