Root leaves smooth, runcinate. Stem leaves narrow. Stem 

 smooth, with two or three branches, each with a yellow flower 

 at the top. Calyx with the outer row of scales very narrow 

 and rough. Crown white, like hairs, longer than the fruit,

SOW-THISTLE. SONCHUS. 

 COMMON SOW-THISTLE. Sonchus oleraceus. 



Plate 12, fig. 6. 



A plant of the fields and orchards, growing two or three 

 feet high, with upright, smooth, hollow stems. Leaves more 

 or less divided, only the lower ones stalked. Flowers small, 

 yellow, numerous, growing in umbel-shaped bunches. Calyx 

 smooth. Whole plant juicy, of a whitish-green color, very 

 nutritious to the cattle, and like many other plants of this class 

 it yields a milky juice, which is narcotic or produces sleep. 



O. S. Blue Alpine Sow-Thistle, Tall Marsh Sow-Thistle, and Corn 

 Sow-Thistle, the last rather common in corn fields. 



DANDELION. LEONTODON. 

 COMMON DANDELION. Leontodon taraxacum. 



Plate 12, fig. 7. 



I think I need scarcely describe this well-known herb, which 

 grows nearly every where, and at almost all times yet, perhaps, 

 you may never have observed that the flowers are not to be 

 found open, except at particular times of the day. It is one 

 of the most correct dial flowers, closing at five in the afternoon, 

 and opening again at seven in the morning. 



" Leontodons unfold 



On the swart turf their ray-encircled gold, 

 With Sol's expanding beam the flowers unclose, 

 And rising Hesper lights them to repose." Darwin. 



The Dandelion is a much despised flower, and yet it is very 

 beautiful, and very useful too. It is eaten instead of Endive,
