150 COMPOUND LEA>T.S, 



verticillato, f. 109, in a whorled manner, the leaflets cut 

 into fine divaricated segments, embracing the foot- 

 stalk, as Sium verticillatum^ Fl.Brit. Eng.Bot. t.o95, 



Auriculatum^f. 110, an auricled leaf, is furnished at its 

 base with a pair of leaflets, properly distinct, but oc- 

 casionally liable to be joined with it, as Salvia triloba, 

 Fl. Grac. t. 17, and Dipsacus pilosus, Engl. Bot. t. 

 877. Linnaeus in the last example uses the term 

 appendiculatum, which is correct, but superfluous, and 

 I have therefore ventured to apply it somewhat differ- 

 ently, />. 146. 



Conjugatum.f. lOS, conjugate, or yoked, consists of 

 only a pair o^ pinnce ov leaflets, and is much the same 

 as b'matum. Instances of it are in the genus Zygo- 

 phjllum, whose name, equivalent to Yokeleaf, ex- 

 pressed this very character ; also in Lathyrus sylves- 

 tris, Engl Bot. t. 805, and latifoliiis, t. 1108. Biju- 

 gum, trijugum, quadrijugum^ multrijugum, &c., ex- 

 press particular numbers 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 compounded 

 are thus distinguished, without any reference to the 

 mode. 



Compositum,/. HI, simply compound, as in the above 

 instances. 



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

 manta, Lihanotis, Engl. Bot. t 138, Mgopodium^ Po- 



* Linnseus, in Phil. Bot. 47, i^ives an erroneous definition of 

 this term, which does not accord with liis own use of it. Pro- 

 fessor Martyn has rightly defined it.
