Here is its leaf
![Page 10: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/10.jpg)
We shall teach InterModeller how to identify these different
trees
![Page 11: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/11.jpg)
Divide these leaves into two groups
![Page 12: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/12.jpg)
The holly, wild almond and eucalyptus are single leaves.
The leaves from the ash, fig, carob and evergreen oak are made up of several smaller leaflets.
![Page 13: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/13.jpg)
These are all single leaves. How can you tell which is which?
![Page 14: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/14.jpg)
There are two ways of doing it.
• The wild almond is definitely green but the eucalyptus is a bluish colour
• The holly is the only one which has prickles
![Page 15: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/15.jpg)
These leaves are multiple leaves
![Page 16: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/16.jpg)
Which one is different from all the others?
![Page 17: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/17.jpg)
The Holm oak leaves are arranged in a fan
![Page 18: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/18.jpg)
The others are arranged in pairs along the stalk.
![Page 19: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/19.jpg)
How do you know which is which?
You count the number of pairs
![Page 20: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/20.jpg)
The fig has two pairs
![Page 21: How to Identify Trees from their Leaves Geoff White Bath Spa University College / University of Malta March 2005.](https://reader035.fdocuments.in/reader035/viewer/2022062407/56649cad5503460f9496ef2c/html5/thumbnails/21.jpg)
The ash has three pairs

The Carob has four pairs
