cyme, and always on the same side of the axis, it as- 

 sumes a peculiar character, termed " scorpioidal" (6). 



(89-) Indefinite Inflorescence. Here the terminal 

 bud, of the main axis included in the inflorescence, con- 

 tinues to develop as a leaf-bud, until sooner or later it 

 is exhausted, and the branch stops ; but it does not pass 

 to the condition of a flower-bud. If we first consider 

 the case where the leaves are alternate, then the second- 

 ary buds in the axils of the leaves or bracteae may either 

 become flowers immediately (fig. 81. a); or they may be

partially developed as branches (ft) which give rise to 

 tertiary buds ; and these may become flowers, or branch 

 in the same way as the secondary buds. When the 

 secondary buds become flowers, without previously 

 branching (a), the inflorescence is termed a " raceme," 

 or " cluster," provided each flower has a pedicel ; but 

 it is called a " spike," if the flowers are sessile, or 

 without pedicels. Where the secondary buds become 

 branches, bearing flowers produced from tertiary buds, 

 the raceme is called " compound" (6). A few of the 

 subordinate varieties of these forms may hei'e be noticed. 

 In such plants as the willow, hazel (fig. 82.), and
