82 ANGIOSPERMAEDICOTYLEDONES 



Mailer describes the strongly odorous white flowers of this species as possessing 

 a corolla-tube scarcely 3 mm. long and expanding above into a four- or rarely 

 five-lobed limb. The bilobed stigma is situated in the entrance to the flower, 

 while the two or rarely three stamens project freely from it. The anthers 

 dehisce laterally, but so widely that their inner surfaces are entirely covered with 

 pollen. The position of the anthers as regards the stigma is variable. Sometimes 

 they diverge widely, so that an insect visitor usually touches an anther with one 

 side of its body and the stigma with the other, thus eff"ecting crossing : sometimes 

 they bend over the stigma, so that insect-visits can easily bring about autogamy, 

 which can also readily take place automatically.
