leaves. These are either pal- L >' rate - 

 mately or pinnately compound, accord- 

 ing to the arrangement of their leaflets 

 upon the palmate or the pinnate plan 

 (p. 87). When the leaflets branch off 

 from one point at the end of the petiole 

 they are palmately compound (cf. Fig. 

 77) ; but when the leaflets branch off 

 upon either side of the lengthened petiole, 

 they are pinnately compound (Fig. 78). 



A. Palmately compound leaves are 

 called ternate\ (Fig. 30, p. 37) when 

 the leaflets are three in number ; and bi 

 or tri-ternate\ when each leaflet is 

 further divided into two or three 

 leaflets, as the case may be. They 

 are called quadrinate\ if they have Fig.;;. -Digitate
