(3) The seed-case is free, when it is not attached 

 along" its sides to the calyx ; adherent, when it is so 

 attached. 



(4) The flower is terminal, when it is at the end of a 

 branch ; axillary, when it springs from the base of the 

 leaf-stem, i. e., from the "axil" of the leaf. 



III. 



THE FRUIT. 



The fruit consists of the ripened seeds and their 

 wraps. For the different kinds see the Fruit Guide, 

 page 29. 



IV. 



THE LEAF. 



(i) A leaf is simple, when it is of one piece, Fig. d ; 

 compound, when there are two or more entirely distinct 

 parts, called leaflets on the one leaf-stem, Fig. c. 



A compound leaf is feather-shaped, when the leaflets 

 are placed along the sides of the leaf-stem, Fig. c; hand- 

 shaped, when all the leaflets radiate from the end of the 

 leaf-stem, like fingers from the palm of the hand.* 



(2) The leaf is entire, when its edge is an even line 

 without indentations ; toothed, when it is set with an 

 indefinite number of sharp or blunt teeth ; lobed, when the 

 indentations are deep and of a definite number, Fig. d. 



*NoTE i. Compound leaves may be once, twice, or three times compound. 



NOTE 2. The leaflets of a compound leaf can be distinguished from a simple 

 leaf by the absence of leaf-buds from the base of their stems.
