to 8 mm. in the latter. The style in the European P. rotundi- 

 folia is relatively longer and also is often more downwardly 

 directed (cf. Fig. 42 A — В and K). In flowers from Denmark 

 and Sweden I have found styles measuring from 7 to 8 mm. in 

 length, while those in the Greenland flowers measured 5 to 

 6'5 mm. only. In addition to this the stamens appear to be

 further forward and somewhat shorter in grandiflora. 



The flowers are formed during the year previous to that in 

 which they open and reach the stage of development shewn in 

 Fig. 40 E—I. The floral buds are larger and more ovoid than 

 are the purely vegetative buds (cf. Fig. 40 В and C].
