compressed reversed ovate fruit, roughish on the upper part ; 

 then comes a little stalk, and a cylinder of long fine hairs 

 called the pappus, from out of which at top issues the long 

 yellow limb of the floret. By-and-by, as it gets older, the 

 little stalk will lengthen into a long slender shaft, and the 

 cylinder of hairs will expand like the rays of an umbrella, 

 and in this way will float away the seeds. But the corolla : 

 this is attached just above the point where the rays of the 

 pappus diverge, and consists of a slender tube which some 

 distance up is split on one side, and so forms the flat strap- 

 shaped ligulate limb. Out of this tube emerges the two stig- 

 matic branches, just beneath which the linear anthers are 

 united into a sheath surrounding the upper part of the style. 

 This cohesion of the anthers into a tube enclosing the style 

 is one of the marks of a Composite flower. 



But we have another illustration, which will serve to explain 

 a different set of these Composite flowers, called the Corymbi- 

 fers from their heads being generally in corymbs the Daisy,* 

 Burns's " bonny gem," which is almost ever and everywhere 

 in blossom. The Daisy is a dwarf perennial herb, with a 

 spreading rosulate tuft of obovate or spathulate leaves, from 

 among which arise the numerous slender stalks, bearing not 

 however a corymb, but a single or solitary head of flowers. 

 Here, the involucre consists of about two rows of green bracts, 

 and within them, at the outer edge of the receptacle, is a row 

 of ligulate female florets, with a very short tubular portion at 

 their base, from whence issues the two-branched style, these 

 having no stamens. These are the ray florets. The other 

 part of the receptacle is filled with small tubular funnel-shaped 

 equal florets, which are hermaphrodite, having both stigmas 

 and anthers. These small tubular disk florets form the yellow
