20 INTRODUCTION. 



parts are named Leaflets, and the divisions of the common stalk 

 are named Partial Stalks. The following are the principal kinds 

 of Compound Leaves : 



Fingered or Digitate (Fig. 73.), when several leaflets rest 

 upon the summit of a common stalk. 



Binate (Fig. 74.), when two leaflets rest upon a common 

 stalk. 



Ternate (Fig. 75.), when three leaflets rest upon a common 

 stalk. 



Suinate, when the leaflets are five. 



Pedate (Fig. 76.), a ternate leaf, having its lateral leaflets di- 

 vided into several others. 



Pinnate or Winged, when several leaflets proceed laterally 

 from a common stalk. Of this there are several varieties. 

 Pinnate with an odd terminal leaflet. (Fig. 77, 80, 84.) 

 Pinnate with a tendril (Fig. 78.), when a tendril or thread- 

 like body terminates the stalk. 



Abruptly Pinnate (Fig. 79.), without a terminal leaflet or 

 tendril. 



Alternately Pinnate (Fig. 80.), when the leaflets are alternate. 

 Oppositely Pinnate (Fig. 77, 78, 79.), when the leaflets are 

 opposite. 



Interruptedly Pinnate, when there are smaller leaflets between 

 the larger. 



Jointedly Pinnate, with joints in the stalk. 

 Recurrently Pinnate, when the leaflets run down the stalk. 

 Pinnate in a It/rate manner (Fig. 77.), when the terminal 

 leaflet is largest. 



Conjugate, Yoked or Paired, when there are only two pinnae 

 or leaflets. 



Bigeminate (Fig. 81.), twice paired. 

 Trigeminate, thrice paired. 

 Biternate (Fig. 82.), twice ternate. 

 Tr item ate, thrice ternate. 

 Bipinnate (Fig. 83.), twice pinnate. 

 Tripinnate, thrice pinnate. 



Without reference to the mode of division, the degrees in which 

 leaves are compounded are expressed in the following terms: 



Compound, as in Fig. 73, 74, 75, 76.
