is flat-topped, the flowering begins at the centre instead of at 

 the periphery, consequently the inflorescence is often described 

 as centrifugal, in distinction from the indeterminate form, which 

 is described as centripetal. 



The principal varieties of determinate anthotaxy are the fol- 

 lowing : 



(i) The Solitary Determinate is one in which there is a single 

 flower at the end of the stem, as in the Wood Anemone, Fig. 189.

(2) The Cyme is a loose cluster on the determinate plan, 

 such as that illustrated in Fig. 190, which represents the inflor- 

 escence of a species of Cerastium. A diffuse and freely branch- 

 ing cyme, like that of the common Elder and the Viburnums, is 

 frequently called a Compound Cyme, and when such a cyme has 

 shortened pedicels and is compactly arranged, as in the inflor- 

 escence of the garden Sweet William, it is termed a Fasicle. 



(3) A Glomerule or glomerulus, is a dense cluster, on the
