Shoots probably more than 1 mm. long, the upper part decompound, 

 the main rachis 3-stelical, obtusely quadrangular, slightly laterally com- 

 pressed, when dry angular and irregularly grooved, ochraceous or yellowish, 

 to 8 mm. thick; pinnae to 50 cm. long, oblong, 3 4-pinnate, the rachis 

 12 mm. broad including the lateral leaves; ultimate branchlets narrowed 

 towards the apex, 5 7 mm. broad at the base. Leaves of the branched 

 portion heteromorphous, entire; lateral leaves remote on the main and 

 secondary rachises, subapproximate on the branchlets; of the main rachis 

 obliquely deltoid-ovate, unequal-sided, shortly acuminate, obliquely cordate 

 at the base, the lower base produced, the largest leaves 8 mm. long by 3V 2 4 

 mm. broad; of the secondary rachises subhorizontal, subobliquely falcate- 

 ovate, the upper base rounded, slightly plicate, the lower base broadly 

 adnate, decurrent, with a small free rotundate-truncate corner, the largest 

 leaves 6 mm. long by 2Y 2 mm. broad; of the branchlets spreading, to 

 2V 2 mm. long; intermedial leaves erect; of the main rachis remote, 

 elongate-deltoid, cuspidate-acuminate, obliquely cordate at the base, the 

 outer base produced, the largest leaves 68 mm. long by 2Y 2 mm. broad; 

 of the secondary rachises obliquely lanceolate-ovate, subfalcate, long- 

 acuminate, obliquely rounded at the base, the outer base produced; of 

 the branchlets imbricate, subabruptly long-acuminate, unequally rotundate- 

 cuneate at the base, the outer base decurrent, the largest leaves 2 mm. 

 long. Spikes solitary and terminal on the branchlets, V 2 1 cm. long, 

 3 4 mm. diam.; sporophylla ovate, acuminate, entire, slightly keeled, at 

 length spreading; macrospores subcompressed, ochraceous, the basal side 

 provided with tuberculiform or shortly rugiform projections; microspores 

 pale-yellow or pale-ochraceous, provided with reticulate, often interrupted

Shoots much elongated, rooting everywhere, reaching a length of 

 90 120 cm., branched, the main rachis conspicuously grooved when dry, 

 3-stelical ; pinnae lanceolate-oblong, 15 cm. long, the erecto-patent pinnulae 

 2V 2 4 cm. long, pinnate with ascending contiguous branchlets narrowed 

 gradually towards the apex. Leaves heteromorphous; lateral leaves hori- 

 zontal or spreading, entire; of the main rachis remote, nearly equal-sided,
