ARRANGEMENT OF FLOWERS OR INFLORESCENCE 27 
the principal ones being: (1) the 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

The flower cluster may be regarded as a modification of that 
lateral arrangement, in which the flowers are scattered on a fully
