Shoots 25 — 50 cm. long, sometimes forked at the base, the lower 

 part simple, stipitiform, the upper part branched, ovate or deltoid-ovate 

 in outline; lower pinnae pinnate, higher forked, highest simple; lower 

 pinnulae of the lower pinnae forked, higher simple. Lateral leaves of 

 the stem very unequal-sided, falcate-ovate, subacute, very minutely den- 

 ticulate on the upper edge except towards the apex, rotundate-cuneate 

 on the upper side at the base, rotundate-truncate and entire on minutely 

 denticulate on the lower side at the base, the largest leaves 4V2 mm. 

 long, 2V2 mm. broad; those of the branches much narrower, somewhat 

 unequal-sided, broadly sessile, lanceolate-oblong, distinctly spuriously veined, 

 pellucid-margined on the upper side in the lower half, cuneate at the 

 upper base, otherwise similar to those of the stem, the largest of the 

 branchlets hardly more than 3 mm. long, 1 mm. broad ; leaves of the 

 upper plane of the stem obovate, acuminate, subaristate-mucronate, broadly 

 auriculate-rotundate on the outer side at the base, subcordate on the 

 inner side, pellucid-dotted, the largest 3 mm. long, 2 mm. broad; those 

 of the branches smaller, entire, narrowly pellucid-margined towards the 

 apex, relatively long-aristate, the largest of the branchlets hardly 2 mm. 

 long, 'A mm. broad, rotundate-subcordate at the outer base, narrowed at 

 the inner base. Spikes nearly square, V2 — IV2 cm. long, IV4 mm. diam. ; 

 sporophylla nearly isomorphous, ovate, shortly aristate-acuminate, piloso- 

 denticulate, pellucid-dotted and -margined in the upper part, keeled, the 

 largest VU mm. long; macrospores orange or yellowish, densely flexuose- 

 rugose on the basal side, if solitary then without apical ribs; microspores 

 orange, sparingly provided with short-stalked capitate projections.

 Shoots 25 — 50 cm. long, the lower part simple, stipitiform, hardly 



more than 2V2 mm. thick, the upper part decompound; pinnae 3 — 4- 

 pinnate ; ultimate branchlets 3 — 4 mm. broad including the lateral leaves. 

 Lateral leaves of the stipe and main rachis very unequal-sided; of the 

 stipe rather erect, obliquely subfalcate-ovate, acute, broadly rounded on 

 the upper (inner) side at the base, rotundate-cuneate on the lower (outer) 

 side, indistinctly spuriously veined, pellucid-margined and minutely den- 

 ticulate on the upper side; those of the main rachis the largest, to 5 mm. 

 long and 2 mm. broad ; those of the branches nearly equilateral, oblong
