2-pmnate, with the lower axillary leaves ovate-oblong or ovate-subcordate, 

 broadest below the middle; pinnae erecto-patent, close, lanceolate-ovate, 

 not articulate at the base, the largest to 25 — 30 cm. long, 8 — 9 cm. 

 broad ; pinnulae crowded, subhorizontal or more ascending, rarely simple, 

 mostly once or twice forked above the middle, to 5 — 6 cm. long, to 

 10 — 12 mm. broad including the lateral leaves and below the forking. 

 Leaves of the pinnae heteromorphous, entire; lateral leaves lanceolate- 

 subfalcate, acute or shortly acuminate, very narrowly pellucid -margined, 

 with the upper base rotundate-cuneate, the lower base rather narrowly 

 rounded or subcordate ; of the secondary rachises rather remote ; of the 

 pinnulae close, subhorizontal, the higher more ascending, the largest 

 6 — 6 '/a mm. long, to 2'/, mm. broad; intermedial leaves erect, unequal- 

 sided, falcate-ovate ; of the secondary rachises whether or not sessile on a 

 subpetioluliform tumefaction, obliquely rotundate-cuneate to narrowly 

 2-auriculate-cordate at the base, the lower acutely acuminate, the higher 

 gradually cuspidate; of the pinnulae obliquely adnate at the base, rather 

 abruptly cuspidate, to ± 3 mm. long, the cusp %--% as long as the 

 blade, the outer base produced, cordate or rotundate. Spikes terminal, 

 sohtary or 2— 3-nate, normally 1 — 1 '/2 mm. diam., sessile or pedunculate, 

 the stalk provided with erected, ovate, acute or acuminate, entire sterile 

 bracts; sporophylla broadly ovate, to 1 mm. long, acuminate, entire, 

 keeled, erect or finally spreading; macrospores whitish, densely and

 near the base; pinnae close, erecto-patent, elongate-lanceolate, narrowed 

 gradually in the upper part, not articulate at the base, the largest to
