PUMPKIN POLLEN PRODUCTION 



The male flower, stripped of its petals and highly enlarged. The 

 anthers are designated bv a and the filaments (combmed mto 

 a column) by b. The anthers are just bursting and the nar- 

 row, labyrinthine slits reveal the pollen grams mside. Ihe 

 swollen iDase of the stamens is hollow and has been cut open 

 so that one can see through it, in order to make its construc- 

 tion clear. (Fig. 8.)
