Shoots wide-creeping, 3-pinnate, probably dichotomous in the lower 

 part, the stem quadrangular, reddish, stramineous-brown when dry, to 2 

 mm. thick, 12 13 mm. broad including the lateral leaves; pinnae remote, 

 to about 12Y 2 cm. long, the rachis 10 12 mm. broad; pinnulae few, 

 partly pinnate, partly repeatedly forked; ultimate branchlets 5 6 mm. 

 broad. Leaves heteromorphous ; lateral leaves of the stem horizontal or 

 nearly so, the lower remote, the higher more approximate, hardly falcate- 

 oblong, shortly mucronulate, minutely serrulate towards the apex, the 

 upper side subappresso-serrulate-ciliolate, rather broadly rounded at the 

 base, the lower side entire, narrowly rotund ate-truncate at the base, the 

 largest leaves 7 mm. long by 2 3 A mm. broad; of the branchlets more 

 ascending, subsimilar, crowded, the upper side rotundate-cuneate at the 

 base; intermedial leaves erect; of the stem remote, deltoid-oblong, sub- 

 acute, long-cuspidate, ciliolate, the outer base shortly rotundate-auriculate, 

 the inner base narrowly rounded, the largest leaves 4 4V 2 mm. long, 

 the cusp about Y 2 as long as the blade; of the branchlets imbricate, 

 smaller, obovate, very abruptly cuspidate, the cusp longer, the base 

 obliquely cuneate. Spikes 4 9 mm. long, 4 mm. broad; sporophylla 

 of the upper plane oblique, oblong, to 4 mm. long, shortly mucronulate- 

 acuminate, minutely serrulate towards the apex, for the rest shortly 

 appresso-ciliolate, keeled, the keel serrulate; of the lower plane less 

 oblique, deltoid-ovate, unequal-sided, shortly cuspidate-mucronate, ciliolate, 

 the lower much the largest; macrospores when young ivory-white or 

 cream-yellow, when ripe yellow-brown or castaneous, minutely punctulate 

 with deciduous, hyaline, papilliform projections; microspores ochraceous, 

 densely but very minutely verruculose.
