Main stem slender, caespitose, trailing, repeatedly dichotomously 

 branched, 8 mm. broad including the lateral leaves, the ultimate branchlets 

 narrower, 2 — 6 mm. long, 1 — 2 mm. broad. Leaves heteromorphous, firm; 

 loaves of the lower plane much spaced even on the branchlets, rather 

 spreading, broadly ovate, nearly equal-sided, blunt, the upper side rounded 

 at the base, minutely piloso-denticulate in the lower half, the lower side 

 entire, subcordate at the base, those of the main stem the largest, VU — 2 mm. 

 long, r/4— IV2 mm. broad, those of the branchlets smaller, to 1 mm. long; 

 leaves of the upper plane Vs as large, erect, ovate, long-acuminate, sub- 

 cuspidate, the outer edge entire or slightly denticulate at the apex, the 

 inner edge minutely piloso-denticulate. Spikes 5 — 15 mm. long, 3 mm. 

 broad ; sporophylla very heteromorphous ; those of the upper plane imbricate, 

 subspreading, unequal-sided, ovate, bluntish, keeled, the base rounded on 

 the upper side, cuneate on the lower side, the upper edge minutely piloso- 

 denticulate in the lower half; those of the lower plane ascending, lanceolate, 

 acuminate, ciliated on both sides; macrospores yellowish, sparingly finely 

 verruculose; microspores yellowish, smooth. — Near S. Belangori Spring, 

 but the lateral leaves relatively shorter and broader, and the branches 

 looser.

Shoots trailing, or ascending towards the apex, 2V2 — 10 cm. long, 

 caespitose, often repeatedly forked, the stem slender, the branches spreading 

 to suberect, simple or little compound. Leaves heteromorphous; those of the 

 lower plane spaced even on the branches, horizontal or spreading, ovate, 

 IV2— 2V2 mm. long, to 'A as broad, pale to bright-green, membranaceous 

 or herbaceous, acute or bluntish, unequal-sided, dilated on the upper side 

 and subcordate at the base, with the upper edge sparingly or remotely 

 denticulate towards the apex, denticulate to ciliate towards the base; of 

 the upper plane 'A as long, ovate, acute to acuminate, rather equally 

 cordate to rotundate-subcordate at the base, with the edges subentire, 

 or sparingly denticulate to ciliate at the base. Spikes commonly solitary, 

 7 'A — 20 mm. long, 3 — 5 mm. broad; sporophylla of the upper plane 

 somewhat ascending, whether or not imbricated, similar to the leaves of 

 the lower plane but not rarely more falcate and acuminate, often relatively
