Shoots 30 50 cm. long, the lower part simple, stramineous, much 

 compressed, to 2 mm. thick, the upper part simply pinnate or sub- 

 2-pinnate. Leaves heteromorphous ; lateral leaves spreading; of the stipe 

 unequal-sided, oblipuely subfalcate-ovate, shortly acuminate, with the 

 upper side minutely piloso-denticulate, ciliolate at the broadly cordate 

 base, the lower side subentire, very minutely denticulate towards the 

 apex, sparingly ciliolate at the truncate-cordate base, the largest leaves 

 3 3Va mm. long and 1% mm. broad; of the main rachis similar to those 

 of the stipe but larger, to 6 mm. long and Va as broad, falcate-ovate, 

 subobtuse, with the upper side rotundate at the base, the lower side 

 subentire, subtruncate-rotundate at the base; of the branchlets similar, 

 ovate-oblong, spuriously nerved, \ l l\ 2V2 mm. long, to 3 A mm. broad; 

 intermedial leaves erect; of the stipe unequal-sided, falcate-ovate, shortly 

 aristate-acuminate, piloso-denticulate, ciliate and hamate-incurvate on the 

 outer side at the base, subtruncate-rotundate on the inner side at the 

 base, the largest leaves 3 mm. long, with the cusp l /z as long as the 

 blade; of the main rachis similar; of the branchlets similar but smaller, 

 entire or rarely denticulate, and cordate on the outer side at the base, 

 sparingly denticulate towards the apex. Spikes solitary, 5 7 mm. long, 

 1 J /4 mm. diam. ; sporophylla ovate, acute, pellucid-margined, shortly piloso- 

 denticulate, keeled, the largest 1 mm. long; microspores minium-red or

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

 quadrangular, 3 mm. thick at the base, the upper part decompound, 

 sub-4-pinnate, ovate in outline. Leaves of the lower part of the stipe 

 rather erect, nearly isomorphous; those of the lower plane unequal-sided, 

 broadly obliquely ovate, subacute to subacuminate, cordate at the base 

 but more broadly on the inner side, the inner edge ciliate in the lower 

 half, minutely denticulate towards the apex, the outer edge minutely 

 denticulate, ciliate at the base, the midrib thickened towards the apex, 

 the largest leaves 4 mm. long, hardly more than 2 mm. broad; leaves 

 of the upper plane as long and as broad, oblique-ovate, shortly aristate- 

 acuminate, the inner side piloso-denticulate towards the apex, ciliate in
