Shoots erect from a decumbent or ascending base, to 40 cm. or more 

 long, the lower part simple, when dry pale-dirty-fuscous, obtusely angled 

 or 2-sulcate on the face, convex on the back, the upper part branched, sub- 

 oblong in outline, the main rachis + 10 — 12 mm. broad including the lateral 

 leaves ; pinnae ascending, the lower 2 — 8-pinnate ; pinnulae simple or forked ; 

 ultimate branchlets varying from very short to 6 cm. long, + 5 — 9 mm. broad. 

 Leaves heteromorphous ; lateral leaves blunt or bluntish ; of the stipe 

 much ascending, remote, unequal-sided, obliquely ovate, bluntish, the upper 

 (inner) side rounded, minutely serrulate, ciliate at the subcordate base, 

 the lower (outer) side less rounded, entire, ciliate at the narrowly 

 rounded base ; of the main rachis approximate, much spreading, elongate- 

 oblong, subfalcate, blunt, provided with a submarginal spurious veinlet 

 on each side, the upper side very minutely serrulate, or entire at the 

 middle, gradually ciliolate at the cordate base, the lower side entire, 

 obsoletely denticulate towards the apex, provided with + 2 — 6 propor- 

 tionally long ciliae at the subahruptly cuneate base, the largest leaves + 

 6 mm. long and + 2^^ mm. broad; of the ultimate branchlets similar 

 but smaller, + 4 — 5 mm. long; intermedial leaves erect, unequal-sided, 

 acuminate; of the stipe remote, subfalcate, rhomboidal-ovate, very minut- 

 ely serrulate, narrowly pellucid-margined, gradually and deciduously cihate 

 towards the obliquely cordate base, the outer base the broadest, produced, 

 the largest leaves + 3^2 — 4 mm. long; of the branched portion similar 

 but growing gradually smaller, with the basal ciliae more persistent; of 

 the ultimate branchlets imbricate, obliquely rotundate-subcordate at the 

 base. Spikes square,' + I'/i — 2 mm. diam. ; sporophylla suberect, ovate, 

 acuminate, keeled, minutely serrulate, to 2 mm. long, at length spread- 

 ing; macrospores reticulate-rugulose, the apical ribs encircled by a ring- 

 shaped crest; microspores provided with verruciform, bacilliform or 

 stipitate-capitate projections on the basal side.

Shoots creeping, + 40 cm. long, pinnate, forked at the base, the 

 stem when fresh pale-red, when dry pale-brown and irregularly grooved, 

 ± l'/2 — 2 mm. thick, the main rachis + 6 — 8 mm. broad including the 

 lateral leaves ; pinnae pinnate ; pinnulae of the largest pinnae compound,
