|Quercus robur - Pedunculate Oak - English Oak|
The twigs of Pedunculate Oak are grey-brown and carry light brown winter buds spirally set, with a cluster of them near the tip. The young shoots bear very little down, and the bud-scales are not downy. The leaves are often bronze to khaki when opening and later are sometimes tinged with red – especially the second growth in July. They have a wavy indented outline, vary in size and lobbing and have a short stalk, on either side of which the leaf usually forms two ear-like lobes called auricles.
Both sexes of flower appear on the same tree in spring. The pale green male catkins are slender, the much less conspicuous female flowers, of like color have appreciable stalks – hence the later cup which holds the acorn likewise has a stalk. Both the acorn and the cup are at first green, but become brown by autumn.
The ‘Oak-apple’ (illustrated) is formed by a minute gall wasp.
The Pedunculate Oak and the Sessile Oak (which it has largely replaced) have sometimes interbred and many Oak wood consist of intermediate forms. Though little attention is given to differentiating between the two timbers, records show that many woodmen have appreciated the difference. Both kinds of tree usually break bud in May, but there is a second period of growth in July or August, when the so-called Lammas shoots are produced.
