Malacca: Ching (Iiidley) ; Negri Sembilan : Kuala Pedas '(Eid- 

 ley 10068) ; Penang (Wallich 3359d). Distrib. India, Malaya,' Aus- 

 tralia. Pare, occurring in rice fields. The plant is described in the 

 Flora of British India as having long stolons, but as Trinien (Flora 

 of Ceylon Vol. V. p. 25) says also of the Ceylon plant, it has none 

 here at least. There being no tanks here for it and the water in the 

 rice fields being shallow or absent, the plant does not float, but is 

 terrestrial.

 2-6 inches tall, stems few slender tufted. Leaves narrow shorter than
