THE DAISY FAMILY. 



293 



In the description of the flowers of the Corapositae, on page 32, the 

 distinction of the florets into "tubular" and " ligulate" was pointed 

 out. (See Figs. 164 and 166.) The mode in which they are disposed 

 and associated is threefold, and furnishes the means of dividing this 

 vast family into three practical and well-defined sections. 



The first comprises those species in which the florets are all ligulate, 

 as in the dandelion. They are called the CichordcecB or chicory-like. 

 (Fig. 167.) 



The second comprises those in which there are none but tubular 

 florets, as in the thistle. These are called Cynarocephalce or thistle- 

 like. 



The third comprehends the species in which the centre or disc of 

 the flower is composed of tubular florets, and the ray or margin of 

 ligulate ones, as in the field daisy. These are called Corymb'iferce

or daisy-like. (Fig. 168.) The only other conceivable disposition, 

 namely, of tubular florets at the margin, and ligulate ones in the 

 centre, has no examples in nature. 



In connection with these foots, the following particulars are also 

 worth observing : — 



In the Cichoraceo! the head of florets is nearly flat ; all the florets 

 are provided with both stamens and pistil ; and the style is not jointed 

 below the stigmas. 



In the Cynarocephal(B the head of florets is usually globular; the 

 florets are almost invariably bisexual ; the style is jointed below the 

 stigmas ; and the corolla is generally much inflated below the mouth.
