Shoots creeping, dichotomous in the lower part, the secondary shoots 

 3-pinnate or sub-4-pinnate, the main rachises subquadrangular, compressed, 

 grooved when dry, stramineous or subochraceous, hardly more than 1V 

 mm. thick, 7 10 mm. broad including the lateral leaves; pinnae remote, 

 to 5 cm. long; pinnulae to 5 on a side, less remote, forked or sparingly 

 pinnate to sub-2-pinnate ; ultimate branchlets short, 4 5 mm. broad. 

 Leaves heteromorphous; lateral leaves remote on the stem, approximate 

 or subcontiguous on the branchlets; of the stem horizontal, obliquely 

 suboblong-ovate, shortly mucronulate, the upper side sparingly serrulate, 

 rather broadly rounded at the base, the lower side entire, narrowly 

 rotundate-truncate at the base, the largest leaves 3Va 5 mm. long by 

 about l lt as broad ; of the ultimate branchlets subhorizontal, very sparingly 

 serrulate on the upper side, unequally rotundate-cuneate at the base, to 

 2Va mm. long; intermedial leaves erect, obovate-oblong, abruptly cuspidate, 

 moderately ciliolate, unequally rotundate-cuneate at the base or the inner 

 base more rounded; of the stem 3 1; 2 4 mm. long, with the cusp 1 U J /2 

 as long as the blade; of the branchlets smaller, imbricate. Spikes short, 

 about 57 mm. long, 3 mm. broad; sporophylla of the upper plane 

 spreading, oblique-ovate-lanceolate, shortly mucronate-acuminate, remotely 

 and shortly ciliate, gradually serrulate towards the apex, to 3 mm. long; 

 of the lower plane suberect, deltoid-ovate, acuminate, shortly ciliate, 

 gradually serrulate towards the apex, hardly keeled, the lower much the 

 largest; macrospores white or yellow to castaneous, very minutely 

 punctulate, soon smooth; microspores pale dirty-ochraceous, densely but 

 very minutely verruculose.
