FORMS OF COMPOUND LEAVES. 



A bipinnate leaf folium 

 bipinnutu'in (fig- 65), 

 as that of the mimosa far- 

 ncsiana. Doubly winged : 

 a common petiole bearing 

 pinnate leaves on each one 

 of its sides. Most of the 

 Aca'cia tribe have bipinnate 

 leaves. 



(Bipinnate : from the Latin, 

 bis, two; and pinna, wing, 

 two-winged.)

BIPINNATE. 



A bipinnate leaf (jig. 

 66), folium bipinnatum. 

 We have an example of 

 leaves of this kind in the 

 Pride of China, Mclia 

 azederach. 



Here the leaflets of the 

 secondary petiole are un- 

 equally pinnate. (See fig' 

 70.) '
