Fl. B. Ind. ii. 433. Wight, Ic. t. 1061. 



A submerged water-herb, stems long, much branched, stout, 

 glabrous, the upper portion often floating on the surface ; 1. 

 very numerous, in whorls of 2-5 (usually 4), \-\ in., the 

 uppermost ones linear, attenuate to base, acute, nearly entire, 

 glabrous, the intermediate ones more or less toothed or 

 pectinate, the lowest ones entirely cut into narrow filiform 

 segm. looking like branched rootlets; fl. sessile, male in the 

 upper axils, female in the lower ones, and a few bisexual ones 

 between them; stam. generally 6, as long as pet; fruit 

 depressed of 4 nearly globular lobes (carp.), glabrous, bluntly 

 muriculate. 



Canals, ponds, and tanks in the dry region ; rather common. Jaffna ; 

 Bintenne; Chilaw; Kalawewa. Fl. all the year. 



Also in the Carnatic, Bengal, and Assam. 



I have never seen anything like a spicate arrangement of the inflo- 

 rescence in our plant. When left growing on mud uncovered by the 

 water the much-divided I. are not produced. Wight's figure above quoted 

 is good for this form, but Clarke (in Fl. B. Ind.) refers it, and also Wight, 

 Herb. n. 942, to M. intermedium DC, which is, however, probably not 

 distinguishable as a species. 



Willdenow, in the original description, gives Ceylon as a locality.
