part simple, compressed, slightly grooved down the face, olivaceous or 

 brownish, to 4 mm. thick, the upper part compound, deltoid-ovate, 30 — 40 

 cm. each way; pinnae 6—8 on a side, the lower 20 cm. long, with the 

 lower pinnulae between pinnate and dichotomous; principal rachises 

 1 — Vh cm. broad including the lateral leaves; ultimate branchlets 8 mm. 

 broad. Leaves heteromorphous ; lateral leaves suberecto-patent ; of the 

 stem obliquely falcate-ovate, bluntish or subacute, minutely denticulate, 

 very unequal-sided, more or less ciliolate at the base, pellucid-margined 

 on the upper side, the upper base cordate-rotundate, the lower base 

 abruptly cuneate, the largest leaves 9 mm. long and 5 mm. broad; of 

 the branches similar but proportionally narrower and growing gradually 

 smaller, contiguous; of the branchlets 2 'A mm. long, more narrowed on 

 both sides at the base ; intermedial leaves erect ; of the stem broadly 

 falcate-ovate, abruptly shortly aristate-acuminate, minutely denticulate, 

 the outer base shortly cordate, the inner base narrowly cordate-rotundate, 

 the largest leaves 5 mm. long and 8V2 mm. broad; of the branches similar 

 but proportionally narrower and growing gradually smaller, those of the 

 branchlets more distinctly auricled on the outer side at the base. Spikes 

 solitary, double or triple, square, 'A — IV2 cm. long, 2 mm, diam. ; sporo- 

 phylla subisomorphous, deltoid-ovate, acute, mucronulate, minutely den- 

 ticulate, keeled, the largest 2 mm. long; macrospores pale-yellow, irregu- 

 larly rugulose, the apical ribs encircled by a rumple-like crest; microspores

Shoots erect, or ascending from a creeping base, 15 — 20 cm. long, 

 the lower part simple, obtusely quadrangular, 1 mm. thick, convex on 

 the back, when dry 3-sulcate on the face and sides, the upper part 

 roundish, triangular or ovate in outline, 3-pinnate; main rachis 5—7 mm. 

 broad including the lateral leaves; lower pinnae to 7 cm. long, deltoid; 

 ultimate branchlets 5— 12V2 mm. long, 2—3 mm. broad. Lower leaves 

 of the stipe somewhat remote, subisomorphous; of the lower plane broadly 

 triangular-ovate, acute, very broadly adnate and narrowly 2-auriculate- 

 cordato at the base, densely fimbriate-ciliate, the largest leaves 2 mm. 

 long, about as broad ; of the upper plane nearly similar, as long but much 

 narrower, acuminate; leaves af the branched portion very heteromorphous;
