a peduncle ; also the

 cluster. The stem of 

 the individual flower in 

 a cluster is a pedicel,

 or crown of the plant, 

 as in dandelion, hya-

 Head and anthodium. Catkin. 

 Panicle. Umbel. Umbellet. 

 Corymb. What are cymose clus- 

 ters? What is a cyme? Glome- 

 rule? Contrast indeterminate and 

 determinate modes of branching. 

 Explain mixed clusters. What 

 is a thyrse? What is meant by 

 the word inflorescence? Define 

 peduncle, pedicel, and scape.
