including the lateral leaves. Leaves of the stem isomorphous, equal-sided, 

 cordate-subulate, minutely denticulate, ciliated at the base; leaves of the 

 branches heteromorphous; leaves of the lower plane lanceolate-oblong, 

 subfalcate, acuminate, nearly equal-sided, cordate or subtruncate-cordate 

 at the base, spuriously striolate-venulose, with the upper edge piloso- 

 denticulate in the lower half, ciliated at the base, the lower edge entire, 

 with 4 ciliae at the base, the midrib thickened towards the apex; of the 

 principal rachises the largest, 2V mm. long, hardly more than 1 mm. broad; 

 of the ultimate branchlets smaller, ascending; leaves of the upper plane 

 ovate, oblique at the base, rather produced, cordate and more or less 

 ciliated on the outer side at the base, acuminate, piloso-denticulate, 

 sparingly pellucid-dotted, the largest leaves V/z mm. long, those of the 

 ultimate branchlets often quite entire. Spikes solitary, 3 7 mm. long, 

 1 r/2 mm. diam.; sporophylla deltoid-ovate, shortly aristate-acuminate, 

 keeled, piloso-denticulate, the ventral ones a little larger, to 1 mm. long; 

 macrospores whitish, irregularly rugulose with short or elongated, flexuose, 

 branched or reticulated ridges on the basal side; microspores orange or 

 yellowish, sparingly provided with stipitate-capitate projections. - - A 

 duplicate of Elmer's No. 7058, occurring in the Buitenzorg Herbarium, has 

 the lateral leaves bluntish, the sporophylla acute, the projections of the 

 microspores partly bacilliform.

Shoots erect, 35 60 cm. long, the lower part simple, IVz 2Y-2 mm. 

 thick, angular, distinctly grooved, the upper (smaller) part branched, 

 broadly ovate in outline; lowest branches 3-pinnate; branchlets 610 mm. 

 long, 2 4 mm. broad including the lateral leaves. Leaves of the stem 

 adpressed, lanceolate-triangular, 3 mm. long, acute, the base truncate to 

 cordate, ciliolate; leaves of the branched portion heteromorphous; those of 

 the lower plane distant, subspreading, broadly lanceolate, 2V* 3V2 mm. long, 

 subfalcate, subacute, not oblique, black-green above, paler, glittering and 

 distinctly spuriously veined beneath, the base truncate, ciliate, rounded 

 on the upper side, partly hiding the rachis, with 4 ciliae on the lower 

 side; those of the upper plane ascending, ovate, oblique, 2 2Vz mm. long, 

 acute, hardly acuminate, keeled; leaves of the branchlets similar but 

 smaller; those of the lower plane close but not imbricate, IV* 2 mm.
