Shoots 40 50 cm. long, the lower part simple, stipitiform, compresso- 

 quadrangular, 2V 2 mm. thick, ochraceous, the upper part 3-pinnate, deltoid 

 in outline; ultimate branchlets 6 7 mm. broad including the lateral 

 leaves. Leaves heteromorphous on both stem and branches; lateral leaves 

 of the stipe spreading, unequal-sided, oblique-ovate, subobtuse or subacute, 

 piloso-denticulate on both sides, the upper base rotundate-cordate, the lower 

 base rotundate-cuneate and sometimes ciliate, the largest leaves 3 mm. 

 long and 2V mm. broad; lateral leaves of the main rachis obliquely 

 falcate-oblong, glaucous-green, rather equal-sided, spuriously nerved, in- 

 distinctly pellucid-margined, subobtuse, the upper side minutely piloso- 

 denticulate, gradually ciliolate towards the narrowly subcordate-rotundate 

 base, the lower side entire, very minutely papilloso-denticulate at the 

 apex, sparingly ciliate at the truncate-cuneate base, the largest leaves 

 6 mm. long and 2 'A mm. broad ; lateral leaves of the ultimate branchlets 

 ascending, close, similar to those of the main rachis but smaller, the 

 largest 3 3V 2 mm. long and Vs as broad; intermedial leaves erect; of 

 the stipe subfalcate-ovate, aristate-acuminate, rather equal-sided, piloso- 

 denticulate on both sides, the outer base cordate-auriculate, sparingly 

 ciliate, the inner base cordate, subentire, the largest leaves 4 mm. long, with 

 the cusp about l / as long as the blade ; intermedial leaves of the main rachis 

 similar to those of the stipe, but the cusp V as long as the blade, the 

 inner base rotundate-cordate; of the ultimate branchlets similar but 

 smaller, imbricate, entire or sparingly denticulate, the outer base rounded, 

 produced, the inner base rotundate-cuneate. Spikes solitary, 1 2V cm. 

 long, 1 3 A 2 mm. diam. ; sporophylla deltoid-oblong, very shortly aristate- 

 acuminate, piloso-denticulate, narrowly pellucid-margined in the lower part, 

 keeled, the largest 1V mm. long, to nearly as broad; macrospores blackish 

 or pale-grey, rugulose or verruculose-rugulose on the lower side, the apical 

 ribs encircled by a nearly wing-like equatorial crest; microspores
