126 THE VEGETABLE WORLD. 
II.— Centrifugal Inflorescence. 
5. The Cyne, or false umbel, is a corymbe with centrifugal inflo- 
rescence, but includes the compound raceme, umbel, and capitulum. 
* TII.— Once Compound Inflorescence. 
6. SprkELETS: where several spikes unite in a spiral arrange- 
ment, as in the grasses, they become spikelets. 
. Umpetxa: where several umbels are united in umbels they 
become Umbella. 
8. The Panictz includes all the many-headed forms of inflo- 
salen as in many grasses. 
. The Buncu, or Fascicutus: a manifold compound cyme, with 
ae and rather crowded pedicels. 
10. The AnrHELA: the inflorescence in the Juncacee (Rushes) 
and Cyperacee (Reeds). 
. GLoMERULE: certain forms of inflorescence, resembling 
Capitulim, consisting of ill-formed, imperfect flowers, as in some 
nettles and rushes. 
Flowers are said to be sessile, in the language of botanists, when 
they are 0 immediately on the stalk, or attached immediately 
to the stalk by 9 small sup- 
port, called a peduncle. The 
peduncle is what is commonly 
stalk of the fruit. The pe 
duncle therefore is to flowers 
what the petiole is to leaves, 
that is, a means of attachment 
to the stem or branch. 
Nevertheless, the analogy be 
tween the peduncle and the 
petiole is limited to the e* 
ternal shape, for the tw? 
organs differ essentially in 
their special organisation. 
Do the flowers, whose con- 
stituent parts we shall soon consider in detail, spring at random 
from the stem, the branches, or the boughs supporting them ?
