The pictures above show the summer habit of English oak (Quercus robur).
Photos of leaf attachment and mature acorns were taken in mid-September 2009.
Morton Arboretum accession information:
tree on left: 668-27*1 plt FF-71/57-19
The leaves of the Quercus robur are lobed and have a very short stalk.
The base of the leaf is describe as "auricular" or ear-like.
Fruit: In July the acorn of the English oak is nearly all "cap". As it matures the acorn will lengthen and the cap will cover less than 1/3 of the nut.
I photographed the tree below for several years while its tag indicated that it was
Quercus robur - English Oak, English White Oak, Royal Oak
701-57*1 gr D-105/75-00
The tag is now broken and only bears the location. This tree may be a hybrid. Usually, these trees grow very large, reaching in excess of 150 feet tall. Lumber from several stout English Oak trees was used to construct the good ship Mayflower. This vessel brought the pilgrims from various ports in England to Plymouth, Massachusetts in the year 1620.
