	Pedunculate oak - Wikipedia, the free encyclopedia
		The Pedunculate Oak or English Oak (Quercus robur) is native to most of Europe, and to Asia Minor to the Caucasus, and also to parts of North Africa.
		A specimen of notable longevity is one in Stelmužė, Lithuania which is believed to be approximately 1,500 years old, possibly making it the oldest Oak in Europe; another specimens, estimated to be about 1,200 years old, grows in Denmark.
		Pedunculate Oak is distinguished from this species by its leaves having only a very short stalk 3–8 mm long, and by its pendunculate acorns.

	Oak Tree
		The English Oak (Q. Robur) ranges from the Urals and the Caucasus, from Mount Taurus and Mount Atlas, almost to the Arctic Circle, growing at an altitude of 1,350 feet in the Highlands of Scotland; its limit nearly coinciding with that of successful wheat cultivation.
		Robur pedunculata), is the most abundant in the southern and midland counties.
		It reaches a less height, but is said to be less liable to the defects known as "cup-" and "star-shake" than the sessile-fruited varieties.
