Shoots erect, the upper part pinnate, the stem 3-steIical with a ten- 

 dency to become 4 — 5-stelical, grooved when dry; pinnae linear-lanceolate, 

 15 — 20 cm. long, 2 — 4 cm. broad; pinnulae ascending, to 4 cm. long, the 

 largest pinnate with 1—3 branchlets on a side; branchlets to 2 cm. long, 

 4 — 5 mm. broad including the lateral leaves. Leaves heteromorphous; 

 lateral leaves remote and horizontal on the stem, close to imbricate and 

 ascending on the branchlets; of the stem triangular-oblong, nearly straight, 

 3 — 4 mm. long, acute, entire, unequally truncate-cordate at the base, 

 broadest on the upper side, the upper auricle incurved; of the ultimate 

 branchlets falcate-oblong, the largest 3 mm. long, 'A as broad, subacute, 

 entire, the upper side rather pellucid-margined, subcuneate in the lower 

 part, conspicuously plicate-auriculate at the base, the lower side truncate 

 at the base; intermedial leaves erect, much smaller; of the stem acute, 

 obliquely truncate-cordate at the base ; of the branchlets acute or acuminate, 

 nearly longitudinally adnate at the base, the inner side straight, the 

 outer side rounded, pellucid-margined, decurrent-cuneate at the base. 

 Spikes IV2 mm. diam.; sporophylla triangular-ovate, to IV2 mm. long, 

 acuminate, entire, pellucid-margined; microspores densely verruculose;

Shoots springing from a scandent, 5 — 8-stelical main stem, pinnately 

 compound, the lower part simple, orchraceous, the stem 3-stelical; pinnae 

 3 — 4-pinnate, with ovate or flabellate pinnulae. Leaves of the stem erect, 

 oblong, subobtuse, with the base varying from rotundate-cuneate to 

 narrowly incurvate-2-auriculate ; leaves of the branches heteromorphous ; of 

 the lower plane rather spreading, oblong, subfalcate, bluntish or subacute, 

 entire, nearly equal-sided, rounded and more or less plicate on the upper side 

 at the base, truncato-cuneate on the lower side at the base ; of the upper 

 plane adpressed, lanceolate, oblique, acuminate, the point bluntish, entire, 

 the base more or less rounded on the outer side. Spikes numerous, 2^2 — 4 

 cm. long when fully developed; sporophylla triangular,- shortly acuminate. —
