1—2 mm. long; intermedial leaves erect, ovate-oblong, narrowly pellucid- 

 margined, with a cusp Vt—V* as long as the blade or longer, minutely 

 denticulate, rather rounded at the base, the largest to IV* mm. long. 

 Spikes 4 — 10 mm. long, 3 mm. broad, narrowed towards the apex; 

 sporophylla of the upper plane subspreading, lanceolate-oblong, acute, 

 minutely serrulate on both sides, keeled; of the lower plane suberect, 

 triangular-ovate, subulate-acuminate and somewhat cuspidate, minutely 

 denticulate; macrospores white or yellowish, smooth, finely verruculose, 

 foveolate or rugulose; microspores verruculose. — I cannot distinguish 

 this from the preceding, and plants gathered in Java agree in my opinion 

 with the diagnoses of both.
