resemble the petals of one 
corolla, and the involuere, 
formed of many imbricated, 
scales, resembles a calyx. This 
head is often called a com- 
pound fluwer. The outer flo- 
rets are the florets of the ray, 
the interior are the florets of 
the disk. See all this illus- 
trated in Figs. 245-250.

from terminal buds. Cyme is Fig. 246. A view of one of them remain-

the flowers open. Thus; in Be lag 
the cyme, the terminal and central flowers open first, but in 
the forms before mentioned, the lower and outer flowers first. 
158. When the cyme is spreading and level-topped, we call 
it a cymous corymb, as in the common Elder; and when not 
level topped, it may become a cymous panicle, as in Chick- 
weed (Fig. 251), Spergula, and Staff-tree (Fig. 234).
