A STUDY OF LEAVES. 



CLASSES OF COMPOUND LEAVES. 



Pinnate and Palmate venation give rise to 

 two classes of compound 

 leaves. A pinnately com- 

 pound leaf has the mid- 

 vein extending from base to 

 apex, bearing a row of leaf- 

 lets on each side. Pal- 

 mately compound leaves 

 have the leaflets all jointed 

 to the petiole.
