reason being that the flowers are smaller in size ; but they 

 also differ somewhat in other details of structure. In some the 

 relation of the different parts to each other is the same as in 

 the typical form (Fig. 33 ^, -B); but in others the pores of the 

 anthers are situated almost exactly in the throat and therefore 

 much nearer to the stigma, which is situated only slightly 

 beyond the throat or practically in it (Fig. 33 C, D). Lindman 

 also mentions differences in the flower, and on Dovre he has 

 observed this form with a flower 7 mm. long, and the anthers 

 protruding and standing rather close to the stigma. Lastly

it may be mentioned that there are even some cases in which 

 the stigma stands somewhat lower than the pores (Fig. 34 D). 



These differences no doubt depend partly upon the growth 

 of the style, but only partly. Ekstam writes: — "der Griffel wächst 

 später noch so dass die Narbe in einer völlig erblühten Blume 

 an den Blütenrand heranragt oder sich ein wenig über diesen 

 erstreckt."
