DIAGNOSIS OF HOLOTYPE: Apparently aqua- 
tic, rooting in shallow fresh water; leaves about 
1.5 m long, at the middle 8.5 cm wide, tapering 
towards both ends, thick coriaceous, green above, 
slightly paler below, 1 -ribbed, 2 -pleated, in sec- 
tion low M-shaped, at midsection with 75 sec- 
ondary parallel veins in each half, tapering 
towards the tip into a long subulate apex, but 
the actual tip not preserved, the base amplex- 
icaul and unarmed, but the margins beginning 
at 20 cm up with prickles 1-2 mm long, 5-10 
mm apart, stout arcuate subulate, pale, ascend- 
ing; the nearby midrib below unarmed; at mid- 
section the margins with spines 6.5-7 mm 
long, 7-16 mm apart, heavy, arcuate subulate, 
ascending, the base much thickened, 4-5 mm 
wide, the tips reddish; the midrib below with 
appressed ascending subulate tipped serrae 2-2.5 
44
