unarmed, obliquely truncate and ciliolate at the moath and produced at one side into 
a triangular acute point, the lower ones, the largest, 2-25 cm, long; branchlets 
attached just at the mouth of their respective spathe, the lower ones, the largest, 
8-10 cm. long with 8-10 spikelets on each side; upper branchlets shorter and with 
fewer spikelets; tertiary spathes infundibular, truncate, produced at one side into a 
triangular acuminate point; spikelets spreading or horizontal, slightly arched, flat and 
comb-like (when carrying full-grown flowers), attached. just at the mouth of the 
spathes; the lower ones, the largest, 15-25 mm. long, brittle, with 6-15 flatly bifarious 
horizontal flowers on each side; spathels bracteiform, broad with a triangular deflexed 
point, this subtending its respective flower; involucre shallowly cupular, slightly bidentate 
and lunately excavate on the axial side; spikelets of the upper part of the partial 
inflorescences 2:5-3:5 cm. long with a proportionate number of flowers Male flowers 
oblong-cylindraceous obtuse, 4 mm. long; their calyx cupular with 3 superficial broad 
teeth; their corolla twice as long as the calyx. Female spadiz decompound, diffuse, 
terminating in a small flattened sheathed aculeolate taillike flagellum, with a few 
not very remote (10 cm, apart) partial inflorescences; primary spathes (the first not 
seen by me) elongate-tubular, closely sheathing, slightly enlarged above, and narrowed 
towards the base, where flat on the inner side, convex on the back and with acute 
margins, thinly coriaceous, fugaciously scaly-furfuraceous, ultimately glabrous, faintly 
longitudinally striolate, aculeolate on the back in their upper part, entire, truncate 
and scarious-ciliolate at the mouth, where suddenly prolonged into a dorsally keeled 
point; partial inflorescences erecto-patent, inserted above the mouth of their own 
spathe with a distinct axillary callus and a distinct (nectarifluous?) transverse rima, 
the lower ones (of the portion of spadix seen by me) 25 m., the uppermost 20 cm. 
long, with 5-6 distichous spikelets on each side; secondary spathes narrowly tubular- 
infundibuliform, unarmed, glabrous, striolate, about 2 cm. long, truncate at the 
mouth and barely prolonged at one side into a broadly triangular point; spikelets 
erecto-patent, rigid, slightly arched, inserted just at the mouth of their own  spathe, 
slightly callous at their axilla, 4°5-6 cm. long, the lower ones, barely longer than 
the upper ones, their axis closely zig-zag sinuous with 10-12 distichous flowers on 
each side; spathels broadly and asymmetrically infundibuliform, narrowed a good deal 
to the base, obsoletely striately veined, horizontally truncate, entire and ciliolate at 
the mouth, prolonged at one side into a triangular acute short patent point; involu- 
crophorum shallow, sub-cupular, posticously bidentate, sub-horizontally subtended by 
its own spathel and laterally attached at the base of the one above; involucre 
moulded on the involucrophorum and not or slightly exceeding ds, shallowly 
cupular, bidentate and with the margin slightly excavate on the side of the neuter 
flower; areola of the neuter flower lunate, sharply bordered. Female flowers small, 
about 3 mm. long. Fruiting perianth shortly cylindraceous, distinctly pedicelliform, 
with 3 very broadly triangular lobes, not or obsoletely striately veined; the segments 
of the corolla as long as the lobes of the calyx but narrower; the filaments of 
the stamens forming by their connate bases an urceolum one-half as long as the 
corolla and crowned by 6 broad, short, triangular teeth. Fruit globose, small, 8-9 
mm. in diam., topped by a small mucro; scales squarrose or loosely imbrieate and 
not adpressed, large relatively to the size of the fruit and few, in 12 series, broadly 
and superficially channelled along the middle, shining, yellowish-brown with a paler 
scarious finely erosely toothed margin and often with a reddish-brown spot at the
