(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. 



(1) 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.
