Vernac. Malacca Jhangi, 
A floating aquatic, apparently very rare. 
Distrib. — C. Europe; Australia. 
A species, with a peculiarly detached distribution, unless it occurs, but has been 
overlooked, in intermediate localities. Roxburgh, writing prior to 1814 (not pub- 
lished till 1832), does not say it is rare; Voigt, writing in 1845, mentions his 
failure to find it near Calcutta. It was rediscovered by T. Thomson in 1855 
in salt-pans south of Calcutta and just to the north of the Sundribun area, and 
again in 1867 by S. Kurz in salt-pans just within the northern boundary of our 
region.
