BOTANY FOR YOUNG PEOPLE. &5 



they may be easily known by producing its seed 

 principally on the margins of the disk. Here 

 are the Marygold and Leaf Cup. 



Polygamia Segregata comprises a set of doub- 

 ly compound flowers, each one having a double 

 calyx, one common to the whole head of flow- 

 ers, and one for each separate floret in the set ; 

 such are the Elephant's Foot and the Globe 

 Thistle. 



L. SONG OF THE SYNGENESIAN TRIBES. 



Though we boast not Triandrids corn and grass, 

 Yet our Thistles feed the laboring ass, 

 And the small birds rejoice in our leafy bowers, 

 As they feed on the seeds of the Groundsel flowers. 

 With us the Cerulean Cyamis is seen, 

 And our own fair Daisy decks the green, 

 And the Succory opens its azure eye, 

 Beneath the light of the summer sky. 

 Fair are our flowers, but yet more fair 

 Are the seeds that lightly float on the air. 

 When the fading blossom has lost its grace 

 A feathery down supplies its place ; 

 And wafts the seed on the passing gale, 

 To its rightful home on the hill or vale. 

 These winged seeds are thickly stored 



In the urn of the purple Salsify ; 

 The Colt's foot keeps a secret hoard, 



And in the Camomile cups they lie. 

 Chief of the woodlands, and queen of the meeds, 

 Accept our fair flowers and our downy seeds.
