8. CONJUGATE, (conjugatuni) yoked ; consists of on-

 Ex. Zygophyllum. 



Observation. Two-yoked, (bijugum) Three-yoked, (trijugum,) 

 Four-yoked, (quadrijugum.) Many-yoked, (multijitgum,) ^&c. ex- 

 press particular numbers of pairs of leaflets, and are used for that 

 purpose where such discrimination is requisite for specific charac- 

 ters, as in the J\limos<e. 



The following terms are applied to the degree of 

 composition ; without any reference to the mode. 



1. COMPOUND, (compo&tum.) PI. 8, fig. 7. Sim-
