Compound Leaves. 



The branches of the mid-rib, instead of forming with 

 the connecting textures of the leaf a single plate, divide 

 it in many species into several smaller plates, so that 

 the main leaf -stalk supports a number of small leaves 

 or leafits *, not merely deeply cut divisions, as in the 

 wing-cleft and other simple leaves. The leafits are 

 accordingly denominated in a similar manner to the 

 simple leaves. It will therefore be altogether unneces- 

 sary for me to repeat in this place the terms enumerated 

 in the preceding paragraphs, with which I presume the 

 beginner has already become quite tired, though they 

 are in some degree indispensable in order to understand 

 botanical descriptions. 



When there is a common leaf-stalk supporting two 

 or more leafits, the compound leaf may be three-fold ! , 

 as in clover; four-fold 2 , as in four-leaved marsilea; 

 five-fold 3 , as in red horse-chestnut; fingered 4 , as in 

 cinque foil ; many-fold, 5 when the leafits are more than 

 seven ; umbelled 6 , when the leafits are disposed like 

 an umbrella, as in several lupins ; and yoked 7 , when 

 the leafits are attached to the sides and not to the top 

 of the leaf-stalk."
