the outer side sparingly ciliato at the produced base; loaves of the 

 branched portion similar to those of the stipe but gradually more contiguous, 

 proportionally longer and narrower; lateral leaves of the main rachis 

 spreading; of the ultimate branchlets 4 mm. long and I'A mm. broad, sub- 

 erecto-patent, cordate-rotundate at the upper base, abruptly cuneate at the 

 lower base; intermedial leaves erect; of the branchlets imbricate, remotely 

 ciliate towards the outer base, sparingly so at the inner base. Spikes 

 solitary or double, 5—7 mm. long or probably longer, IVj— 2 mm. diam.; 

 sporophylla subisomorphous, deltoid, narrowly pellucid-margined, denticulate, 

 ciliate at the base ; macrospores rather rugulose or reticulate, and provided 



with an equatorial ring; microspores

Shoots erect or ascending, 25 — 30 cm. long, pinnate, the stem obtusely 

 angular, convex on the back, bisulcate down the face when dry, grey- 

 brown; pinnae pinnate; lower pinnulae pinnate again; branchlets 8 — 5 — 7 

 mm. broad including the lateral leaves. Lateral leaves of the stem 

 somewhat remote, spreading (the lower ascending), subequilateral, linear- 

 oblong, nearly straight, rather bluntish, the upper side very minutely 

 denticulate in the upper half, denticulate in the lower part, ciliolate at 

 the auriculate-cordate base, the lower side entire, or obsoletely denticulate 

 towards the apex, sparingly ciliate or ciliolate at the rotundate-cuneate 

 base, the largest leaves 6 mm. long, 2 mm. broad ; of the secondary 

 rachises similar, more ascending, close, somewhat smaller, blunt; of the 

 branchlets similar, ascending, more rotundate-cuneate at the lower base, 

 more or less pellucid-margined on the upper side in the lower half and 

 dorsally spuriously veined, the largest leaves 2 — 3 mm. long; intermedial 

 leaves of the stem broadly oblique-oblong, somewhat remote, erect, 

 cuspidate-acuminate, denticulate, ciliolate in the lower part, obliquely 

 cordate, and produced on the outer side, at the base, the cusp 'A — Vs as 

 long as the blade, the largest leaves 4 mm. long; of the branchlets 

 similar, smaller, imbricate, rather pellucid-margined, less copiously den- 

 ticulate and ciliolate, rather narrowly rotundate-truncate at the inner 

 base, the cusp relatively longer. Spikes terminal or subterminal, single 

 or double, square, 5—15 mm. long, I'A — 2 mm. diam.; sporophylla 

 triangular-ovate, shortly aristate-acuminate, keeled, denticulate ; macrospores 

 whitish or yellowish, more or less rugulose to reticulate, the apical ribs
