Also in South Africa. According to M. S. Evans (/.e.) the Howcrs of L. Dreyei 

 are visited by sunbirds, wbidi insert their beaks into the slits between the corolla- 

 lobes and cause the flower to open with a jerk. As the flower opens, the anthers are 

 •said to be all broken sharply oft", and to fly off into space with great violence, parting 

 with their pollen as they go. The point of breakage is evidently at the junction 

 between the slender and thickened parts of tlie filament, judging from dried speci- 

 mens, and it is apparently the sudden contraction and coiling up of the thickened 

 portion of the filament which causes the explosive opening of the flower.
