oblique, lanceolate, to 10 — 20 cm. long, 2—5 cm. broad, the rachis 4 mm. 

 broad including the lateral leaves; branchlets 4 mm. broad at the base, 

 narrowed rather gradually towards the apex. Leaves heteromorphous; 

 lateral leaves very remote on the stem, less so on the secondary rachises, 

 approximate on the branchlets; of the stem oblique, obliquely suboblong- 

 ovate, hardly unequal-sided, shortly acuminate, entire, the upper base 

 rounded, the lower base rotundate-truncate, the largest leaves 3 mm. 

 long, V/i mm. broad; of the branches suboblique-oblong, obsoletely den- 

 ticulate towards the mucronulate apex, very narrowly pellucid-margined, 

 the upper side rotundate-cuneate in the lower half, plicate-subauriculate 

 at the base, the lower side subcordate-truncate or truncate-rotundate, the 

 largest leaves 2V2 mm. long, 1 mm. broad; of the branchlets smaller, 

 more narrowed and hardly plicate at the base; intermedial leaves erect; 

 of the stem remote, subfalcate-ovate, acuminate, entire, shortly 2-auriculate 

 at the base, the outer auricle a little produced, subhamate-incurvate ; of 

 the branches falcate-ovate, long-acuminate, subcuspidate, entire, narrowly 

 pellucid-margined, very obliquely adnate at the base, the outer base 

 rounded and more or less decurrent, the inner base narrowed; of the 

 branchlets imbricate, cuneate-decurrent on the outer side at the base. 

 Spikes solitary, 5 — 15 mm. long, IV2 mm. diam. ; sporophylla deltoid-ovate, 

 to 2 mm. long, acuminate, slightly keeled, narrowly pellucid-margined; 

 microspores cream-yellow, provided with crowded stipitate-capitate pro- 

 jections; macrospores

Shoots divaricating-scandent, 1 — 8 m. long, the lower part probably 

 one or more times forked, the stem to 2 cm. thick, 3 — 5-stelical, fragile, 

 pale-ochraceous or stramineous-green, the secondary shoots sub-4-pinnate ; 

 pinnae ovate, the rachis 4 mm. broad including the lateral leaves; 

 ultimate branchlets IV2 — 3 mm. broad. Leaves entire; leaves of the stem 

 remote, the lower subisomorphous; lateral leaves obliquely falcate-ovate, 

 more or less acute, unequal-sided, narrowly 2-auriculate-cordate at the 

 base, to 4V2 mm. long, to 2 mm. broad; intermedial leaves nearly similar 

 but less unequal-sided, to 4V2 mm. long, to I'A mm. broad; leaves of the 

 branches heteromorphous; lateral leaves very oblique and somewhat 

 remote on the secondary rachises, less oblique and close or imbricate on 

 the ultimate branchlets; of the secondary rachises falcate-ovate, bluntly
