ii. Leontodon (Dandelion) 



i. L. Taraxacum (Common Dandelion). Dandelion, (from the 

 French Dent-de-lion, lion's tooth) is the popular name of many of 

 the larger yellow flowers belonging to this Sub-order. The true 

 Dandelion may, however, be readily known by the following 

 characters. The leaves all spring from the root, and are deeply 

 cut, with the sharp lobes pointing backwards ; the flower-stalks are 

 hollow, smooth, and leafless, and bear a single flower ; the outer 

 scales of the involucre are reflexed ; the pappus is stalked and 

 white ; the heads when in fruit are of a globular form ; and the 

 receptacle, after the fruit has been blown away, is convex and dotted. 

 The dandelion has valuable medicinal properties, and is some- 

 times used as a salad. Fl. nearly all the year round. Perennial.
