1542. C. defloratus L. (Herm. 

 MuUer, 'Alpenblumen,' pp. 418-22.)— 

 In this species the heads contain 100- 

 200 purple florets, and are only 20 mm. 

 below, but 25-30 mm. above, where 

 the corollas bend outwards. The tube 

 of the corolla is 7-8 mm. long, and its 

 bell about 5 mm. deep, with 5 linear 

 diverging lobes 6-7 mm. in length. 

 On both sides of the lowest lobe the 



bell is cleft to a depth of 3 mm., so that insects with a proboscis 3 mm. Ion 

 reach the nectar which rises into the belJ.
