Leaf of the Day - Day 26

An English Oak and a Sessile Oak.


The two trees are closely related and hard to tell apart from a distance. However ...

The English Oak (Quercus robur), AKA the Common or Pedunculate Oak, has rounded lobed leaves that are attached to the twig by a short stalk. The acorns, meanwhile are on a long stalk. 

In contrast, the Sessile Oak (Quercus petraea) AKA the Cornish, Irish or Durmast Oak, has leaves with irregular lobes - some of which can be pointed. The leaves are attached to the twig by a long stalk while the acorns are attached with almost no stalk - the opposite arrangement to the English Oak.


So now you know.
