maintaining its tubular character above splits longitudinally 

 below into five or six segments, so that linear openings are 

 formed. The result is that when an insect settles on the 

 flower the tubular corolla is very easily depressed, exposing 

 the style surrounded on all sides by pollen. Any pollen that 

 is not removed by the insect falls from the style, for the 

 short hairs on the style by which it is held in position very 

 soon fade. The style then splits above into three segments, 

 exposing for the first time the sticky stigmatic surface now 

 ready for pollination. 



The Round-headed Rampion is one of the five Swiss 

 species with rounded, not elongated, flower-heads. Three 

 of them can at once be put aside, because they are usually 

 much smaller plants and have less than twelve flowers to a 

 flower-head, whereas the Round-headed Rampion has always 

 more. Fhyteuma Scheuchzeri is distinguished from this 

 plant by its lilac flowers, longer stalked and usually 

 broader basal leaves, and especially by the circle of leaves 

 immediately beneath the flower-head, which are longer than 

 the flowers themselves.
