SAXJFRAGEAE 421 



and blocked by stiff hairs projecting ])crpendicularly from the style. The anthers 

 at first project somewhat beyond the stigmas, but ultimately stand at the same level, 

 so that automatic self-pollination must take place in horizontal or oblique flowers, 

 though cross-pollination is favoured during insect-visits. After fertilization, the sepals 

 curve upwards. 



Besides hermaphrodite flowers, Kirchner noticed shrubs bearing female ones. 

 The stamens of these are so short that their anthers (which do not dehisce) are 

 at the level of the petals, or may even be situated more deeply in the receptacle.
