Harper : On the Flora of South Georgia 



Most of the above I have found in only one or two localities 

 each. It may be of interest to note that Limnanthcmum aquati- 

 cum may be either a rooting or a floating plant. It seems to 

 make no difference to the plant whether its petioles are attached to 

 the rootstock or not, for I have found the plants in great abund- 

 ance crowded together along the shore of a pond and floating 

 free, with their petioles broken off below the inflorescence, but 

 with flowers open as usual. 



In wet ditches and open muddy places I have found the follow- 

 ing species : 



Sparganium androcladum (En- Jussiaea leptocarpa Nutt.

 Sagittaria latifolia Willd.
