3o8 THE STORY OF PLANT LIFE 



4^ mm. long, the tube 2J mm., the upper part or 

 throat, 2 mm., and bell-like. The anther-tube does 

 not project beyond the bell. The anthers open 

 inwards, and pollen falls on the upper part of the 

 tube. The upper branches of the white style are 

 projecting when the flower opens, and are covered 

 with hairs, sweeping the pollen up on the latter. The 

 stigmatic part itself is included in the corolla below 

 the hairy part. When the stigma is ripe the papil- 

 lose portion lengthens and becomes receptive. 

 Neighbouring florets are pollinated with pollen from 

 the sweeping hairs, as the florets are close together. 



The insect visitors include a large number of 

 Butterflies, the Peacock Butterfly, Hemiptera, Bees^ 

 Flies. 



The " achenes " are provided with a pappus and 

 wind-dispersed. 



The plant was used formerly as a tonic.
