138 COMPOUND LEAVES. 



latifblius, t. 1 108. Bijugum, trijugum, quadri- 

 jugum, multijugum, &c. express particular num- 

 bers of pairs of leaflets, and are used for that 

 purpose where^such discrimination is requisite for 

 specific characters, as in Mimosa. 



The different degrees in which leaves are com- 

 pounded are thus distinguished, without any re- 

 ference to the mode. 



Compositum, f. Ill, simply compound, as in the 

 above instances. 



Decompositum,f. 112*, doubly compound, as Atha- 

 manta Libanotis, Engl. Eot. t. 138, JEgopodium 

 Podagraria, t. 940, and Fumaria claviculata y 

 t. 103. 



Supradecompositum, f. 1 1 3, thrice compound, or 

 more, as Caucalis Anthriscus, t. 987, C. dau- 

 coides, t. 197, and Sunium flexuosum, t. 988. 

 But 



Bigeminatum, twice paired, as Mimosa Unguis cat i,

* Linnaeus, in Phil. Bot. 4? , gives an erroneous definition of this 

 term, which does not accord with his own use of it. Professor Mai- 

 tyn has rightly denned it.
