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, vdth 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, 2Vz 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 VU ram. long, those of the 

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

 1 — IV2 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 

 dupUcate 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, IVs — 2 'A mm. 

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

 broadly ovate in outline; lowest branches 3-pinnate; branchlets 6 — 10 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-2 — S'A 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— 2V2 mm. long, 

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

 smaller; those of the lower plane close but not imbricate, IV2 — 2 mm.
