1650. C. tectorum L. Warnstorf describes the flower mechanism of this 

 species as follows (Verh. bot. Ver., Berlin, xxxvii, 1896). 



The long stylar branches are covered with spinose sweeping-hairs, all of which 

 project at right angles, and not only push out from the anther-cylinder, but also hold fast 

 the polyhedral pollen-grains. These are covered with minute drops of oil, and beset 

 with spinose warts on their edges. In the second stage of anthesis the stylar branches 

 roll spirally downwards, and thus come into contact with the pollen-grains that still 

 remain among the sweeping-hairs, so that if crossing has not been effected by insects, 

 autogamy is rendered possible.
