'mostly spreading, lanceolate, to 15 cm. long; ultimate branchlets to 3 'A 

 cm. long, 3V2 — 5 mm. broad. Leaves heteromorphous ; lateral leaves of 

 the lowest Vj — Vs of the stipe unequal-sided, erect or suberect, remote, 

 broadly oblong, bluntish, the inner side very minutely denticulate towards 

 the base, the outer side entire or subentire, the outer base truncate- 

 rotundate, the inner base auriculate-cordate, the auricle rounded or hamate- 

 incurvate; lateral leaves of the branched portion spreading; of the main 

 rachis the largest, approximate, similar to those of the stipe but somewhat 

 falcate, indistinctly spuriously veined, to 5 mm. long and 3 mm. broad, 

 the upper side entire or obsoletely denticulate, more distinctly denticulate 

 in the lower part, broadly rotundate-cordate at the base, the lower side 

 entire or subentire, abruptly cuneate-truncate at the base ; of the branchlets 

 smaller, to 2V2 mm. long, relatively much narrower, more distinctly 

 spuriously veined, less unequal-sided, the upper side cuneate in the lower 

 half, rounded at the very base; intermedial leaves more or less erect; of 

 the stipe remote, broadly oblong, acuminate, entire or obsoletely denti- 

 culate, 2-auriculate-cordate at the base, the outer auricle produced, 

 somewhat hamate-incurvate ; of the main rachis similar but more close, 

 the largest 3 — 4 mm. long, mucronate-acuminate or shortly cuspidate; of 

 the branchlets smaller, imbricate, the inner base narrowly rounded or 

 rotundate-cuneate, the outer base rotundate-cordate. Spikes square, to 

 2 cm. long, I'A mm. diara.; sporophylla isomorphous, ovate, acute, keeled, 

 entire or sparingly denticulate; macrospores yellow-brown or dirty-brown, 

 densely irregularly rugulose on the basal side, the apical- ribs encircled 

 by an irregular rugiform ring, the ridges not rarely glauco-pruinose ; 

 microspores dirty-orange, provided with scattered conical or bacilliform 

 projections on the basal side.'
