branchlets, rather ascending; of the stem unequal-sided, oblique-ovate, 

 34 mm. long, dark-green, moderately firm, bluntish, with the upper 

 side subentire or very minutely denticulate, more distinctly denticulate 

 in the lower half or towards the broadly rotundate-subcordate base, the 

 lower side entire, adnate at the base, with a narrow subtruncate-rotundate 

 free corner; of the branchlets similar but smaller, to 2 mm. long; leaves 

 of the upper plane very small; of the stem remote, triangular-ovate, 

 mucronate-acuminate, more or less minutely denticulate, rather rounded 

 at the base; of the branchlets imbricate, rather cuneate at the base. 

 Spikes 6 J /4 12 Va mm. long, 2 2V* mm. broad; sporophylla of the upper 

 plane crowded, suberecto-patent, oblique-ovate, bluntish, minutely den- 

 ticulate on the upper side; of the lower plane erect, smaller, broadly 

 ovate, cuspidate-acuminate, keeled, denticulate; macrospores pale-flesh-

Shoots trailing, pinnately divided, forked at the base, the main stem 

 7 mm. broad including the lateral leaves. Lateral leaves remote on the 

 stem, close on the ultimate branchlets; of the stem horizontal, very 

 unequal-sided, much produced on the upper side, broadly subcordate-ovate 

 or ovate, bluntish or subacute, mucronulate, the upper side minutely 

 denticulate towards the apex, ciliolate towards the broadly rotundate- 

 cordate base, the lower side minutely denticulate, narrowly rounded at 

 the base, the largest leaves 3V 2 mm. long, 2 mm. broad; of the ultimate 

 branchlets smaller, ascending; intermedial leaves unequal-sided, obliquely 

 broadly ovate, aristate-cuspidate, minutely denticulate towards the apex, 

 ciliate at the base; of the stem the largest, 2V mm. long, 1V mm. broad, 

 cordate at the base; of the branchlets smaller, broadly rotundate-cuneate 

 at the base. Spikes 4 mm. long, 2V mm. broad; sporophylla of the 

 upper plane spreading, very unequal-sided, ovate, acute, denticulate, 

 strongly keeled, the largest 2 mm. long; of the lower plane erect or 

 suberect, equal-sided, broadly ovate, acuminate, denticulate, keeled, the
