54 AN INTRODUCTION 
rounding all the Florets. 3. The Florets 
monopetalous and feffile. 4. The Anthere 
of each Floret five in Number, and growing 
together in a Cylinder. 5. A monofpermous 
Germen under each of the Florets. Of thefe 
Properties, the two laft are. effential to a 
compound Flower ; but obferve, that there 
are fome whofe Calyx contains only a fingle 
Floret, as Echinops, Stoebe, Corymbium, and 
Artemifia. 
Compound Flowers are of three Kinds: 
¥, Ligulate, when all the Corollule, little Co- 
rolle, of the Florets are plane, flat, fhaped 
like Ligula, a narrow Tongue, or Fillet, and 
expanded towards the outer Side, 2. Tubu» 
hofz, when all the Corollule of the Florets 
are Tubulofe, and nearly equal. 2. Radiate, 
baving Rays, when the Corollulz of the Dif, 
middle Paris, are Tubulofe, and thofe of the 
Circumference, Margin, of another Form: 
Which Variation affords three Cafes, viz. 
when the Corollule of the Circumference 
are either /igu/ate, as in Achillea; tudbulofe, 
but unlike the tubulous Florets of the Difk. 
as in Centaurca; or naked, as in Artemifia 
and Gnaphalium. A com pound Flower ufu- 
ally confifts of many Florets, but rarely of 
adeterminate Number of them.
