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—B 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

more erect in the typical form of P. rotundifolia, but bent 
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—/. The floral buds are larger and more ovoid than 
are the purely vegetative buds (cf. Fig. 40 B and C).
