inclosed by a sheath (spathe) (Aroide). 
3. Raceme (racemus). The individual flowers have 
long pedicels (Crucifere) (Fig. 16 6). 
(4. Head or Capitulum. The flowers sessile on a flat- 
tened or head-shaped axis (Composite) (Fig. 
16 d and e). 
5. Umbel (umbella). On the axis, which is abbrevi- 
ated to 0, originate numerous flowers with stalks 
Shortened 4° 0F pedicels of equal length (Umbellifere). The 
axis. umbel is often compound, so that small um- 
bels (umbellets) stand at the end of every ray. 
The umbels and umbellets are then mostly sur- 
rounded by a circle of bracts, called the involu- 
cre or involucel (involucrum, inyolucellum) 
(Fig. 16 c). 
II. Cymose INFLORESCENCE.—The main axis is over-topped 
by one or several more strongly developed lateral axes. 
(1. Cyme (cyma’). Below theterminal flower origi- 
nate numerous, mostly equally strong lateral

Pseud-axis. } 2. Dichusium.* Below the terminal flower origi- 
nate two equally formed lateral shoots (false 
| dichotomy) Valerianella (Fig. 16 m). 
(3. Bostryx.* The over-topping lateral shoots of 
| successive members arise on the same side of 
their main axis (Fig. 16 7). 
4, Cincinnus.* The over-topping lateral shoots 
arise alternately on opposite sides of their 
| main axis (Asperifoliacer) (Fig. 16 # and 7). 
By the combination of several types of inflorescence with each 
other is formed a compound inflorescence. To this belong the - 
corymb (Sambucus) and the anthela.
