Main stem slender, caespitose, trailing, repeatedly dichotomously 

 branched, 3 mm. broad including the lateral leaves, the ultimate branchlets 

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

 leaves 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, I 3 / < 2 mm. 

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

 leaves of the upper plane Vz 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. Belangeri Spring, 

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

 looser.

Shoots trailing, or ascending towards the apex, 2Vz 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, 

 r/2 2V 2 mm. long, to Y 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 V 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, 

 7V 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
