ARRANGEMENT OF FLOWERS OR INFLORESCENCE 27 



the principal ones being: (1) tlie position of the flower on the 

 stem, whether terminal or lateral; (2) whether the flowers are 

 single or in clusters; (3) whether the terminal or lateral flowers 

 of a cluster open first; and (4) 

 the character of the cluster in 

 regard to shape and compact- 

 ness, which depend upon the 

 elongation of the stem region 

 bearing the flowers and the length 

 of the individual flower stalks. 

 These features taken singly, to- 

 gether, and along with some 

 minor features form the basis 

 upon which floral arrangements 

 are classified. 



Flowers develop from buds 

 and buds are either terminal or 

 lateral on the stem. So as to 

 position, flowers are either ter- 

 minal or lateral on the flower axis. 

 Flowers borne singly are called 

 solitary flowers, and solitary flowers may be terminal, as in some

The flower cluster may be regarded as a modification of that 

 lateral arrangement, in which the flowers are scattered on a fully
