Rather variable as to the length of the internodes and petioles, 

 doubtless in connection with the station. Also the shape of the leaves 

 varied from cuneate to square or even somewhat cordate at the base 

 and from almost entire to 3-cleft with more or less incised lateral 

 lobes. I have several times seen it with developed fruits, notwith- 

 standing the fact that it propagates principally by vegetative shoots, 

 but open flowers I sought for in vain. The floral buds as well as the 

 heads of fruits were always submerse, and consequently I think that 

 it must here be cleistogamous and the polhnation must take place under 

 water. 



B. hyperboreus was a rather rare plant in small lakes and ponds 

 or other wet localities.

The Ellesmereland specimens are soonest to be referred to f. 

 huniifusa, (Wahlenb.) Hartm., that is to say the same in which the 

 species occurs in Greenland. It was very small, and grew in its only
