The Viola tricolor or Pansy, the Gratiola, 

 the Marfipiia, and many plants besides, have

 received the pollen whose vapour renders it 

 turbid, and whose minute husks afterwards 

 remain upon the stigma. The same pha^no- 

 menon takes place several successive days. 



In opposition to similar facts, proving the 

 synchronous operation of these organs, Ponte- 

 dera has, ^vith more observation than usual* 

 remarked that in the umbelliferous tribe the 

 style frequently does not appear till the an- 

 thers are fallen. But he ought to have per- 

 ceived that the stigma is previously perfected, 

 and that the style seems to grow out after- 

 wards, in a recurved and divaricated form,
