 sparingly denticulate, entire at the base, the outer base cordate-rotundate, 

 produced, the inner base cuneate-rotundate, with the cusp 1 U as long as 

 the blade. Spikes 4 10 mm. long, 2 mm. diam. ; sporophylla subiso- 

 morphous, deltoid-ovate, very shortly aristate-acuminate, pellucid-margined 

 in the lower half, piloso-denticulate, ciliate at the base, the largest 1V 

 mm. long; macrospores yellowish- white, provided with short or elongate, 

 straight, flexuose, branched or connected rumples on the basal side, the 

 apical ribs encircled by an equatorial wing-shaped crest; microspores 

 minium-red or yellowish, provided with shortly stipitate-capitate and very 

 minutely punctiform or rugiform projections.

 acuminate, both sides minutely denticulate towards the apex, ciliate 

 towards the subauriculate-cordate base, the largest leaves 2Va mm. long, 

 1V 2 mm. broad; those of the main rachis spreading, obliquely subfalcate- 

 ovate-oblong, subauriculate on the upper side at the base, truncate- 

 rotundate at the lower base, indistinctly spuriously veined, the upper 

 side piloso-denticulate in the upper half, pellucid-margined, gradually ciliate 

 towards the base, the lower edge denticulate at the apex, ciliate at the 

 base, the largest leaves 4Y mm. long, 2 mm. broad; those of the branches 

 similar, of the branchlets the smallest, 1V 2 mm. long, V mm. broad, 

 close, distinctly pellucid-margined on the upper side; intermedial leaves 

 erect; of the stipe obliquely deltoid-ovate, shortly aristate-acuminate, 

 both sides minutely denticulate in the upper part, ciliate towards the 

 subauriculate-cordate base, the largest leaves 2 3 A mm. long; those of the 

 main rachis similar but nearly equal-sided, the largest 3Va mm. long, 

 more sparingly ciliate at the base, pellucid-dotted, the cusp .somewhat 

 longer; those of the branches similar, of the ultimate branchlets l*/4 2 

 mm. long, with the cusp 3 A as long as the blade, the base whether or 

 not ciliated, more produced on the outer side. Spikes solitary,. 5 15mm.
