The flowers face downwards and are visited by small hovering flies. 

 To get the honey secreted round the base of the style they must hold on to 

 the stamens and style. The latter being the longer is touched first and so 

 receives pollen from the underside of the insect's body. Later on the 

 visitor, in sucking the honey catches hold of the stamens and rubs against 

 the anthers. Self-pollination would occur by the bending of a stamen 

 against the stigma. {Koernier.)
