leaves of the lower plane imbricate at least at the base ; of the main 

 rachis horizontal or nearly so, subfalcate-oblong, acute, broadest on the 

 upper side, both sides minutely and copiously denticulate, the upper side 

 gradually ciliolate in the lower half, cordate at the base (not auriculate), 

 the lower side ciliate towards the cordate (narrowly auriculate) base, the 

 largest leaves 2 'A 3Va mm, long 'and 2 /s as broad; of the branchlets 

 ascending, smaller, proportionally much narrower, acute, the upper side 

 minutely serrulate, ciliolate-denticulate at the rotundate-subcordate base, 

 the lower side minutely serrulate in the upper half, entire in the lower 

 half, very sparingly ciliolate-denticulate at the rounded base, the largest 

 leaves IVa 2 mm. long, under Va as broad; leaves of the upper plane 

 erect; of the main rachis somewhat remote to imbricate, subfalcate-ovate, 

 acuminate-cuspidate, ciliolate-denticulate on both sides, pellucid-margined 

 on the outer side, less so on the inner side, fimbriate-ciliolate at the 

 somewhat obliquely rotundate-subcordate base, the largest leaves 3 mm. 

 long, the cusp V as long as the blade; of the branchlets similar but 

 smaller, imbricate, more obliquely rotundate-cuneate and not or hardly 

 ciliolate at the base. Spikes solitary, square, 5 mm. more or less long, 

 11 V mm. diam.; sporophylla ovate-oblong, acute or mucronate-acuminate, 

 slightly keeled, serrulate, more or less narrowly pellucid-margined, macro-

Shoots probably 20 40 cm. long, the lower part simple, stipitiform, 

 reddish-stramineous, compressed-quadrangular, 1 IVa mm. thick, the upper 

 part sub-3-pinnate ; branchlets 4 mm. broad including the lateral leaves. 

 Leaves .heteromorphous ; lateral leaves of the stipe unequal-sided, the 

 lower suberect, the others spreading, remote, obliquely falcate-ovate, 

 shortly acuminate, the upper edge minutely denticulate in the upper 

 part, ciliate towards the subauriculate-rotundate base, the lower edge 

 entire or obsoletely papillose-denticulate, ciliate at the rotundate-cuneate 

 base, the midrib thickened towards the apex, the largest leaves 3 mm. 

 long and 2 1 ;* mm. broad; lateral leaves of the main rachis similar, 

 horizontal, to 5 mm. long; those of the branches obliquely subfalcate- 

 ovate or -oblong, subobtuse, the upper side pellucid-margined, minutely
