245. MIXED CLUSTERS. 

 Often the cluster is mixed, being 

 determinate in one part and in- 

 determinate in another part of 

 the same cluster. This is the 

 case in Fig. 184. The main clus-

 but it is really a thyrse. Lilac is 

 a familiar example of a thyrse. In

 is, the inflorescence is cymose, 

 corymbose, paniculate, spicate, soli-

 works on descriptive botany. Thus
