Swamps; from the Uppee Gangbtic piain to Assam and BrBMA, and south- 

 ward to Ceylon — Distkib. China, Mulaya, Afr. trop. 



Stem 3-5 ft., lower internodes often as thick as the thumb, rooting. Leaves 

 6-12 by J— ^ in., many-nerved, base hardly contracted j sheath smooth ; ligule 

 short, membranous. Spihe 6-10 in. by 4 in. diam., strict j rachis stout, terete, 

 channelled. Spiheleta spreading, much longer than their pedicels, green, her- 

 baceous. — Very near the American P. vilf aides, Trin. (Jiuviatile, Nees). Bentham 

 reduces P. interrupfum to P. rmjwus, but they are very different plants.

P. indicum appears to pass insensibly into P. interruptum and P. rm/osuroides, 

 the former of which differs in its stouter habit, the latter in its caudiform spike and 

 more minute rounded spikelets. Though so abundant in the Plains to the eastward 

 of the Jumna, I have seen no specimens from the west of that river ; nor from 

 Africa. The following are the principal Indian forms, in describing which I have 

 used the word spike in a conventional sense. 



Var. indicum proper ; stem 6-18 in. erect or decumbent at the base, leaves 

 narrow, spikes ^-2 in. cylindric green whitish or blue-purple, spikelets yjj-i in. 

 ovate-lanceolate acute straight or decurved glabrous or sparsely setose. — The common 

 Plains form. P. phalaroides, Roem. & Sch. is a common state with more setose 

 spikelets; it is P. indicum, 13, Wight Cat. 1611 B.
