grow upon pedicels of about equal length along the 
rachis, Fig. 141. 
A Glomerule is formed by nearly sessile clusters 
of flowers in the axils of opposite leaves, Fig. 142. 
The Corymb is a flower-cluster, with a short ra- 
chis, the lower pedicels of which are lengthened, so 
that the cluster is flat at top, Fig. 143. 
Fig. 143. Fig. 144. 
An Umbel has no rachis, and the pedicels are of 
nearly equal length, Fig. 144. 
A Compound Raceme, or Panicle, has a long 
rachis, and the flowers grow upon branches of the 
pedicels. When such a cluster is thick and cone- 
shaped, it is called a Thyrse , Fig. 145. 
A Compound Corymb is a corymb with the flow¬ 
ers growing upon branches of the pedicels, Fig. 146. 
A Compound Umbel has a second umbel, or urn- 
bellet, upon each pedicel, Fig. 147. 
Most of the clusters pictured in this exercise are 
represented as without bracts, that differences in their 
modes of branching may be more easily compared. The 
pictures represent certain styles of flowering, and each
