 subangular and irregularly grooved, castaneous or dirty-coloured, the 

 upper part 4-pinnate, ovate in outline, the main rachis 7 mm. broad 

 including the lateral leaves; pinnae ovate or lanceolate, to 20 cm. long, 

 the rachises puberulous; ultimate branchlets hardly more than 2 mm. 

 broad. Leaves heteromorphous; leaves of the stipe scattered; of the 

 lower plane acute, minutely denticulate on both sides, broadest at the 

 rounded upper base, straight at the lower base, the largest 2V2 mm. 

 long and 1 mm. broad; of the upper plane obliquely ovate, aristate- 

 acuminate, slightly keeled, the inner side minutely denticulate, rounded 

 at the base, the outer side subentire, slightly decurrent at the base, the 

 largest leaves 2Vj mm. long and IVj mm. broad, with the cusp 'A as 

 long as the blade; leaves of the branched portion gradually approximate; 

 leaves of the main rachis the largest; of the lower plane very remote, 

 spreadmg, to S'A mm. long and IV2 mm. broad, obliquely lanceolate, 

 acute, the upper side minutely denticulate, pale-margined in the lower 

 74, rotundate-cuneate at the base, the lower side entire, rotundate-cuneate 

 at the base; of the upper plane obliquely ovate, to 2 'A mm. long and 

 IV2 mm. broad, subcuspidate-long-acuminate, the cusp Vs as long as the 

 blade, the sides partly narrowly pellucid-margined, the inner side remotely 

 denticulate, rotundate-cuneate at the base, the outer side hardly den- 

 ticulate, cordate-auriculate at the base, the auricle rounded ; leaves of the 

 branchlets similar but smaller; of the lower plane approximate, to IV2 

 mm. long and ';2 mm. broad, bluntish, narrowed at the base. Spikes 

 solitary, V/i mm. diam.; sporophylla subisomorphous, ovate, mucronate, 

 keeled, denticulate, the ventral ones the largest, to IV2 mm. long; macro-

Shoots stiffly erect, to 30 cm. long, the stem slender, the lower part 

 simple, the upper part 3-pinnate; pinnae much ascending, deltoid-oblong, 

 5 — 7V2 cm. long, the rachises deciduously and finely hairy; branchlets 

 sometimes 2V2 — 4 cm. long, 1 — Vk mm. broad including the lateral leaves. 

 Leaves of the branches heteromorphous; lateral leaves crowded or nearly 

 close, suberect, liable to curl up in drought, nearly as broad as long,
