140 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. Kerrianus. 
acuminate above to an acute tip which is prolonged into a setaceous apex: they are 
thinly papyraceous, green, and almost glossy on both surfaces; have 3 slender 
costae bearing a few fine bristles on the upper surface; underneath the mid-costa 
only is bristly; transverse veinlets very numerous and sharp; the margins are 
smooth, except very ear the apex where they are minutely bristly-ciliate; the 
intermediate leaflets are 16—18 em. long, 13—18 mm. broad; those near the base 
are not much smaller, but from about the middle of the leat upwards gradually 
decrease in size, the two terminal being the smallest, and very shortly united by 
their bases. 
Male spadiz flagelliform, very elongate (2:30m. in one specimen,) supradecom- 
pound, bearing 6 partial inflorescences, with a very slender main axis especially in 
its upper part, where it is thread-like, and clusely armed with very minute claws, 
but yet furnished with diminutive partial inflorescences even to very near its 
extreme point; primary spathes tubular, all closely sheathing, very elongate and 
entire: the lowest slightly flattened, obliquely trancate and entire at the mouth, 
7 mm. broad with acute spinulous edges; the upper spathes are very briefly 
produced at the apex into short obtuse or split auriculiform limbs, more or less 
armed with small claws; the partial inflorescences form rather dense, somewhat 
irregular panicles 20—25 em. long; their main axis is very slender and sinuous, 
and carries several gradually-decreasing spikelets bearing branchlets; secondary 
spathes cylindrical, very closely sheathing, smooth; tertiary spathes elongate- 
infundibuliform ; spikelets alternate and approximate on the branchlets, spreading, 
inserted outside the mouths of their respective spathes, very regularly pectinate, or 
strongly flattened with very regularly and closely-set, horizontal, bifarious contiguous 
flowers usually 15—20 mm.or at times 25 mm, long and 5 mm, broad; spathels, 
very approximate, concave, bracteiform, produced at one side into a triangular, 
deflexed acute point; involucre cupular, bidentate. Male flowers narrowly oblong, 
terete, small, a little over 2 mm. long, and about *66 mm. broad; the calyx 
campanulate, 3-lobed ; the corolla twice, or more, as long as the calyx, almost 
polished, Female spadiz...... TUNE t

OpseRvATIONS.—It is apparently related to the 
the leaf-sheaths prolonged into a very elongate ocrea. -It is however 
e by the leaf-sheaths and ocrea being both armed with bristly spines: 
with numerous narrowly-lanceolate leaflets; and by the very 
flattened, pectinate spikelets bearing 
other New Guinea species 
having

by the short lsaves 
elongate flagelliform spadix having small, 
very small contiguous flowers.
