In some .specimens collected by Fyson in S. India (Xo. 1475 ! 4371 !) 

 some or all the leaves are linear to linear oblong, attaining 10 X 1 mm., 

 obtuse or retuse, the nerves anastomosing. As the parts of the plant, on 

 which these leaves occur, show no flowers, we conclude that they were 

 submerged in analogy to what takes place in Rotala tenuis under similar 

 circumstances.
