the largest leaves 3 mm. long and !*/ 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-

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

 I 1 /* mm. broad, with the cusp Y 2 as long as the blade; those of the 

 branches growing gradually smaller, of the primary branches narrower, 

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

Shoots erect or ascending, 10 17V* 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, 23 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 IVa 2 mm. long, to *U 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 3 A to as 

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

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