denticulate, cuneate and ciliolate in the lower half, ciliate and very 

 narrowly auriculate at the base, the lower side entire, ciliate at the 

 rotundate-cuneate base, the midrib thickened towards the apex, flanked 

 by spurious veinlets, the largest leaves IVs 2 mm. long, V 3 A mm. 

 broad; leaves of the upper plane erect; of the stipe and main rachis 

 falcate-ovate, aristate-acuminate, piloso-denticulate on both sides, ciliate 

 at the base, the inner base rounded, the outer produced, cordate-auriculate, 

 the cusp Vs Va as long as the blade, the largest leaves 3 4 mm. long; 

 of the branches similar, shorter, more sparingly denticulate, much longer 

 cuspidate, often non-ciliate at the base. Spikes 3 9 mm. long, nearly 

 2 mm. diam. ; sporophylla deltoid, shortly aristate-acuminate, piloso- 

 denticulate, keeled, the ventral ones somewhat larger, 1V mm. long; 

 macrospores pale-reddish, yellowish or reddish-blackish, provided with 

 flexuose, branched or reticulate rumples on the basal side, the apical 

 ribs encircled by an equatorial ring; microspores yellowish or orange, 

 provided with stipitate-capitate projections on the basal side.

Shoots 20 30 cm. long, the lower part simple, stipitifbrm, greenish- 

 or reddish-stramineous or bluish-grey, compresso-quadrangular, 2V mm. 

 thick at the base, the upper part sub-3-pinnate, ovate in outline. Leaves 

 heteromorphous ; lateral leaves spreading; of the stipe remote, very 

 unequal-sided, broadly oblique-ovate, broadest on the upper side, shortly 

 acuminate, minutely denticulate on both sides, the upper side gradually, 

 the lower suddenly, ciliated towards the cordate base, the largest leaves 

 2 J A mm. long and nearly 2 mm. broad; of the main rachis similar to 

 those of the stipe but larger, rather entire on the lower side, to 5 mm. 

 long and 3 mm. broad; of the ultimate branchlets approximate, less 

 unequal-sided, lanceolate-falcate, bluntish, hardly spuriously veined, with 

 the upper side pellucid-margined, minutely denticulate, gradually ciliate 

 towards the base, cuneate in the lower half, narrowly rounded at the 

 very base, the lower side entire, ciliate at the truncate-rotundate base, 

 the largest leaves 1Y 2 mm. long and Vs 1 mm. broad; intermedial 

 leaves erect ; of the stipe remote, unequal-sided, broadly oblique-ovate, 

 shortly denticulate, shortly cordate and ciliolate at the base, the largest 

 leaves 3Vi mm. long, with the cusp V as long as the blade ; of the main 

 rachis similar to those of the stipe but somewhat smaller, pellucid-dotted,
