on the other hand, the pollen situated higher up had. Thus, 

 there was both as regards the position of this pollen and the 

 degree to which it had germinated, every reason to believe 

 that it came from the anthers of the same flower. For the 

 rest, an immense quantity of pollen may be found deposited 

 on the styles. Petals total length 15 mm, cal,-st. 10 mm long, 

 cor.-st. 8 mm, pistil 8 — 8^/2 иап^? o^ which the styles about 

 3 mm.

 From Nova Zembla, gathered by Th. Holm. F, Anthers open; 

 many pollen-grains in them, some of which are germinating. (E. W.) 



I have seen flowers from Nova Zembla (Fig. 40) which 

 in a way stand intermediate between the two forms described 

 by LiNDMAN. The petals are just visible at the throat of 

 the calyx (Fig. F)^ consequently, they are longer than in 

 the one of his forms, but shorter than in the other; the 

 anthers are at the level of the stigmas; much as in one of 

 his forms, open, and quite evidently able to carry out self- 

 pollination. In addition, the pollen was germinating in 

 abundance not only in the anthers, but also on the stigmas. 

 In Nova Zembla fruit is set which ripens.
