Also in South Africa. According to M.S. Evans (/.c.) the flowers of ZL. Dreget 
are visited by sunbirds, which 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 off, 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 the 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.
