rather long} (14-17 cm. in length), slightly channelled above near the base, flat 
upwards, its margins very acute and armed—as is the lower rounded surface—with 
scattered, short, straight aculei; rachis acutely bifaced and smooth above, regularly 
and closely armed beneath with solitary, rather small claws; leaflets numerous, 
equidistant, rather closely set, linear-lanceolate, gradually finely acuminate into a 
subulate bristly tip, somewhat attenuate at the base, where suddenly plicate at 
their insertion on the rachis, thinly papyraceous, about the same colour on both 
surfaces, shining above, distinctly and rather densely bristly above on the acute mid- 
costa and on one rather slender nerve on each side of it; beneath only the 
mid-costa is bristly; margins distinctiy and appressedly spinulous; the largest leaflets, 
those a little above the base, 15-17 em. long and 8-10 mm. broad; the two ter- 
minal slightly smaller than the others and quite free at the base. Male spadiz 
à . . Female spadiz very slender, filiform, about as long as the leaves; with 
very few partial inflorescences; primary spathes very elongate and very narrow, 
very closely sheathing, the lowest somewhat flattened and acutely two-edged, the 
others cylindraceous, finely and densely aculeate, truncate and entire at the mouth; 
partial inflorescences spreading, very small and short (5-6 cm, long), inserted above 
the mouth of their own spathe, and with very few (usually 2) spikelets on each 
side distinctly callous at their upper axilla; secondary  spathes scabrid, tubular, 
slightly enlarged above or very narrowly infundibuliform, closely sheathing, ob- 
liquely truncate at the mouth, where acute at one side; spikelets very short (15-20 
mm. long) and relatively thick, horizontal, inserted at the mouth of their own 
spathe with a distinct axillary callus, and bearing 4-5 rather remote flowers on 
each side;  spathels  cylindraceous at the base, scabrid,  striately veined and ' 
slightly infundibuliform in their upper half, horizontally truncate and entire at 
the mouth; involucrophorum sub-cupular, almost hollowed laterally into the base of 
the spathel above its own; involucre asymmetrically sub-cupular, 
striately veined limb; areola of the neuter flower rather large, 
parts unknown, 
with an irregular
