35 m high or less, the stems sparingly pubescent, the lower parts 

 prostrate and rooting at the nodes. Leaves membranaceous, 

 lanceolate, greenish when dry, 6 to 9 cm long, 1.5 to 2.5 cm wide, 

 base acute or acuminate, gradually narrowed upward to the 

 blunt apex, margins slightly undulate, both surfaces with nu- 

 merous small cystoliths, glabrous, or the midrib on the lower 

 surface more or less hirsute with short hairs; lateral nerves 5 

 or 6 on each side of the midrib, distinct, ascending, anastomosing ; 

 petioles 8 to 20 mm long. Spikes terminal and axillary, solitary 

 or in threes, shortly peduncled, up to 3 cm long. Bracts submem- 

 branaceous, green, not margined, orbicular-ovate to broadly 

 obovate, 6 to 7 mm in diameter, or the obovate ones up to 8 mm 

 in length, their margins sparingly ciliate, apex abruptly and very 

 shortly acuminate; bracteoles oblong-lanceolate, slenderly acu- 

 minate, margins sparingly ciliate, about 5 mm long. Calyx seg-
