COMPOSITE FLOWERS. 



garden flowers have no seeds at all, although they 

 are of this kind ?" 



" Because by the gardener's art the flower has 

 been rendered double ; that is, those parts which 

 were once stamens have been transformed into 

 petals, and petals without stamens cannot produce 

 seed. Several of the composites are very hand- 

 some and ornamental ; but there are others which 

 are simply useful, as artichokes, succory, endive, 

 lettuce, camomile, and wormwood.* Your fa- 

 vourite and sweet-scented southernwood is also 

 one of this tribe. 



"Passing by some foreign and little known 

 plants, I must here mention the EVENING PRIMROSE 

 and the MYRTLE tribes. The evening primrose, ( 

 whose tall spikes of pale-yellow blossoms enliven 

 the shady parts of our gardens, gives its name to 

 a tribe which includes the pretty (Enothera, with 

 its wild relations the Willow-herbs, and also the 

 Clarkia, the Fuschia, and others. To the same 

 tribe belong two species of plants called En- 

 chanter's Nightshade,J one of which is often a 

 troublesome weed in gardens."
