Botanical name: Quercus robur Family: Fagaceae (Beech family)
English oak is a majestic deciduous tree, up to 42 m tall, with a wide
spreading crown, up to 24 m. The trunk is short and sturdy, with deeply
fissured gray brown bark. Leaves are small, 3-5 in long, with 3-7 pairs of
rounded lobes, and extremely short leaf-stalks. They remain deep green
long into autumn before turning brown and then persisting on the tree well
into winter. The typical oak flowers are hanging catkins which appear with
the emerging leaves in early spring. The acorns are elongate, about 1 in
long, with a cup that covers 1/3 of the nut. They are borne singly or in
clusters of 2-5 which dangle on a single long 1-4 in stalk (peduncle).
English oak can be distinguished from the similar North American species,
white oak (Q. alba), by its leaves which have earlike lobes on the bases
and extremely short petioles. English Oak is native to Europe, West Asia
and N. Africa. It is cultivated in Kashmir.
