VIII. Take a leaf of the Five- Finger (or the Garden 

 Strawberry), examine carefully, and notice : 



1. The stipules. 



2. T&z petiole. 



3. The blade composed of several pieces or leaflets (3 to 8). 



4. Make a sketch to show these parts. 



IX. The leaf just studied is called a compound leaf, be- 

 cause the blade consists of more than one piece. It is 

 also called a palmately compound leaf because the leaflets 

 radiate out from one point, as the fingers do from the palm 

 of the hand. 



X. Take a Rose leaf, examine, and notice : 



1. Ite stipules. 



2. '\\itpetiole. 



3. The compound nature of the blade consisting of several 



leaflets. 



4. The differences between this and the last leaf studied, as 



regards the position of the leaflets ; viz. that in the 

 Rose they arise from different points along what cor- 

 responds to the midrib of the simple blade. 



5. Such a leaf as that of the Rose is said to be pinnately 



(from pinna, a feather) compound. 



6. Make a sketch of the Rose leaf. 



XI. Examine a Parsley leaf and notice : 



r . That it is several times compound, or decompound. 

 2. That the parts are arranged in a palm ate fashion.
