reappear, but much smaller, in its upper part; above (the rachis) is acutely bifaced 
with the angle smooth and the faces rather concave, and is furnished at the sides 
with some very small aculei; leaflets very numerous,’ very regularly equidistant 
from the base to the top; in the intermediate portion about 3 cm. apart on 
each side, closer towards the apex, alternate or subopposite, papyraceous, rigidulous, 
subconcolorous on both surfaces, slightly paler underneath,  subshining above, 
elodgate-lanceolate or  ensiform, slightly attenuate at the base, where suddenly 
plicate, and not callous at their insertion, very gradually long-acuminate into a 
subulate very slender tip, which is sparingly bristly spinulous at the sides, with 
3 slender coste, which are all furnished above with brown bristles (these 
scarcer on the mid-costa) and naked beneath; transverse veiulets sharp, rather remote 
and interrupted; margins finely and very appressedly spinulous, . slightly thickened 
by a marginal nerve; all leaflets almost of the same size, those a little above the 
base, the largest, 40-45 em. long, 20-25 mm. broad, only those near the summit 
narrower and shorter; the two of the terminal pair very narrow and free at 
the base. Male spadic . + s. +> Female spadiv simply decompound, elongate, 
terminating in a very long and robust flagellum (2-8 m. long in one specimen) 
which is strongly armed with robust, very broad-based black-tipped claws; primary 
spathes ... + « +} partial inflorescences elongate-paniculate, the one seen by me 
38 cm. long with 8 spikelets on each side; secondary spathes tubular-infundibuliform, 
closely sheathing, somewhat narrowed at the base, unarmed, indistinctly striately 
veined, truncate at the mouth, prolonged at one side into a short erect point; 
spikeleis cylindraceous, rather thick, inserted just outside the mouth of their own 
spathe and arising erect from this and then arched downwards, not distinctly callous. 
at their upper axilla; the largest, the lower ones, 5-6 cm. long, with 5-6 flowers 
on each side, the upper ones shorter ; spathels tubular-infundibuliform, slightly narrowed 
to the base, horizontally truncate and entire at the mouth, prolonged at one side 
into a short triangular point, involucrophorum exsert from its own spathel and 
laterally attached at the base of the one above, almost regularly cupular not callous 
at its axilla, slightly bidentate on the side next to the axis; involucre cupular, 
truncate, slightly lunately emarginate and bidentate on the side of the neuter 
flower; areola of the neuter flower distinctly lunate, rather concave, with sharp 
borders, Fruiting perianth not pedicelliform. wt subspberic, about 12 mm; 
in diam., suddenly topped by a rather large muero; scales in 17-18 series, yellowish- 
brown, rather shining, slightly channelled along the middle with a very dark 
intramarginal line, the short tip and margin erosely toothed. Seed subdimidiately 
globular, 8 mm. long, with uneven but not pitted surface, very convex on the 
Duk and Wah a very deep ‘circular chalazal fovea on the rapbal side; albumen 
equable ; embryo basal. | 
HammaT.—Australia: N. E. Queensland, on argillaceous ground in damp places 
of the primeval forests on the middle and upper Barron River, at about 500 
metres above the level of the sea, Diels No. 8388 in Herb. Berol. 
Opsrrvations,—I have seen of this the terminal portion of a fruit spadix with 
a single partial inflorescence and the upper part of a plant with two leaves and their 
sheaths: these are not gibbous above and are without any trace of a flagellum, but
