 pinnately divided, the following once or twice forked, the higher simple; 

 ultimate branchlets long, 3—6 mm. broad. Leaves heteromorphous; lateral 

 leaves of the stem ascending, subapproximate, somewhat obliquely falcate- 

 ovate, acute, the uppei* side pellucid-margined, minutely denticulate, 

 rounded at ths base, the lower side minutely denticulate at the rotundate- 

 cordate base only, the largest leaves 7 mm. long by 4 mm. broad; inter- 

 medial leaves of the stem obliquely falcate-ovate, aristate-acuminate, the 

 outer edge minutely denticulate near the apex, ciliate at the produced 

 incurvate-auriculate base, the inner edge rotundate-cordate at the base, 

 minutely denticulate, the largest leaves 7 mm. long; leaves of the branches 

 growing gradually smaller; lateral leaves of the branchlets close, subacute, 

 rather rotundate-cordate at the base, slightly spuriously veined, the upper 

 side minutely denticulate in the lower half, indistinctly pellucid-margined,, 

 ciliolate at the base, the lower side entire between the minutely den- 

 ticulate apex and ciliate base, the largest leaves 2V2 — 3 mm. long, less than 

 half as broad; intermedial leaves of the branchlets smaller, long-acuminate, 

 subcuspidate, rotundate-cuneate at the inner base, cordate at the outer 

 base, the auricle rounded. Spikes square, terminal, 'A — I'A cm. long, 

 2 — 2V2 mm. diam., solitary on abbreviated lateral branchlets or 2 — 4-nate

Shoots probably 50 cm. or more long, the lower part simple, stipiti- 

 form, compressed, fulvous or fulvo-olivaceous, to 5 mm. thick, when dry 

 slightly 2-sulcate on the face, convex on the back, pubescent on the 

 angles, as are the rachises, the upper part branched, the main rachis 

 10 — I2V2 mm. broad including the lateral leaves, the ultimate branchlets 

 6 — 10 mm. broad; lower pinnae to 20 cm. long, subpinnate, the central 

 2 — 3 times forked, the higher simple. Leaves heteromorphous; lateral 

 leaves of the stipe remote, ascending, 5 mm. long by 2 'A mm. broad; 

 of the branched portion more contiguous, obliquely subfalcate-ovate, the 

 apex very minutely denticulate, acuminate, the point bluntish, both sides
