} buds averaged. 



' Flowers with 4 stamens were, with very few exceptions, four-parted throughout 

 and similarly for the flowers with 5 stamens. 



-By the use of the word "averaged" it is, in all cases, meant that all the buds 



treated were within 2 mm. either larger or smaller than the size stated. 



^ In this case, the only instance of such treatment, a large bud was allowed to 



open and shed pollen normally and two hours after the opening of the anthers the 

 stigma alone was pinched off.
