 the edges and ending in a fine point. Flowers small, blue or pink, in 

 little terminal heads, surrounded by a broad, leafy involucre, deeply 

 divided into about 8 lobes, longer than the flowers themselves. Corolla 

 with a slender tube, little more than a line long, and 4 small, spreading 

 lobes. Calyx-teeth enlarged after flowering, forming a leafy crown to 

 the fruit. 



In cultivated and waste places, in temperate Europe and Asia, 

 extending far to the north as a weed of cultivation. Common in the 

 greater part of Britain, but scarce in the north of Scotland. /I. tkj
