the largest leaves 3 mm. long and IVa mm. broad, acutely acuminate; 

 those of the branches spreading, rather remote, growing gradually smaller ; 

 of the ultimate branchlets more ascending, hardly 2 mm. long, 1 mm. 

 broad, less unequal-sided, less acute, more or less indistinctly spuriously 

 veined, subentire on both sides towards the apex ; leaves of the upper 

 plane erect, cuspidate ; those of the stipe broadly ovate, narrowly pellucid- 

 margined and piloso-denticulate on both sides, keeled towards the apex, 

 cordate-rotundate on both sides at the base, the largest 3 mm. long and 

 r/i! mm. broad, with the cusp 'A as long as the blade; those of the 

 branches growing gradually smaller, of the primary branches narrower, 

 with the cusp Vs as long as the blade; of the ultimate branchlets to 1 

 mm. long and 'A mm. broad, with the cusp Va as long as the blade, 

 rotundate-cuneate at the base.

Shoots erect or ascending, 10 — IT'A cm. long, simple or forked in 

 the lower part, 3 — 4-pinnate in the upper part, the stem terete or grooved, 

 stramineous, 1 — 2 mm. thick at the base, 5—6 mm. broad including the 

 lateral leaves; pinnae to 7 cm. long, with moderately crowded branches; 

 ultimate branchlets 5 — 10 mm. long, 2 — 3 mm. broad. Leaves hetero- 

 morphous on both stem and branches ; leaves of the lower plane spreading, 

 horizontal or subdeflexed on the stem, ascending on the branchlets; of 

 the stem somewhat remote, oblong, to 3 mm. long, 1 mm. broad, bluntish, 

 the upper side minutely denticulate in the lower part, broadly cordate 

 and much produced at the base, the lower side entire, more narrowly 

 rotundate-truncate at the base; of the branchlets crowded, subfalcate, 

 the largest IV2 — 2 mm. long, to V4 mm. broad, rotundate or rotundate- 

 cuneate on the upper side at the base, more narrowed on the lower side 

 at the base, for the rest similar to those of the stem ; leaves of the 

 upper plane erect and adpressed; of the stem remote, oblong, 2 mm. 

 long, rather suddenly very long-cuspidate, sparingly serrulate, the inner 

 base rotundate-cordate, the outer base produced, auriculate-cordate, the 

 auricle slightly hamate-incurvate ; of the branchlets imbricate, obovate- 

 oblong, cuspidate-acuminate, 1 mm. long, sparingly denticulate, the inner 

 base rather cuneate, the outer base produced, cordate, the cusp 'A to as 

 long as the blade. Spikes solitary, partly terminal, partly axillary in 

 the higher forks, short, square, 1 — IV2 mm. diam. ; sporophylla iso-
