38 OF THE ROYAL BOTANIC GARDEN, CALCUTIA. CC. pi/osissimus. 
taper somewhat towards a rather acute base and from the middle upwards are 
gradually acuminate to a setiform tip; are thinly papyraceous, green and 
subconcolorous on both surfaces, subtricostulate, or with the mid-costa very 
sharp and another costa more slender on each side of it; all 3 furnished with 
long bristles on their upper surface, and quite smooth underneath; secondary nerves. 
extremely slender or inconspicuous; transverse veinlets rather sharp, distant, connecting 
the coste; margins sharp, furnished with numerous, long, Jight coloured, soft and 
very delicate, conspicuous cilia as much as 5-7 mm. long; the largest leaflets are 
those of the middle, which are in the upper leaves 10-12 em. in length and 5-8 
mm. in width, and in the radical ones 15-17 cm. by 7-9 mm.; the upper and 
lower leaflets are gradually smaller, those near the mouth of the sheaths being 
only 3-5 em. long and 3-4 mm. broad: the two of the terminal pair are quite 
free at the base, 6-7 cm. long and very narrow. Male spadic slender. about 3 mm. 
thick in its lower sheathed part, flagelliform but rather rigid and terminating in 
a short, slender, aculeolate appendix; on the whole it is 60-70 cm. long, simple- 
decompound, has 4-5 not very approximate, gradually diminishing partial inflorescen- 
ces; primary spaihes tubular, very narrow, very closely sheathing: the two lowest 
very long and similar, slightly flattened, entire and obliquely truncate at the 
mouth, armed all round with very small solitary scattered claws; partial inflor- 
escences panicled, inserted near or a little above the mouth of their own 
spathe, slightly arched and spreading: the largest, lowest, is 10-13 cm. long and 
has 8-10 alternate and  bifarious, slightly arched spikelets on each side: the 
upper ones are gradually shorter and’ have fewer spikelets ; secondary  spathes 
tubular-infundibuliform, glabrous, entire, and almost horizontally truncate at the 
mouth, flat on the inner or axial side, convex and rather densely armed with small 
claws externally, strongly striately veined; spikelets inserted just at the- mouth of 
their own spathe, spreading, flattened, with a slender axis, glabrous in every part: 
the largest, lowest, are 2:5-3 cm. long, and have 10-12 flowers on each side: the 
others are gradually shorter and have fewer flowers; spathels broadly and obliquely 
infundibuliform, truncate, entire and glabrous at the mouth, produced externally into 
a triangular acute point, very strongly striately-veined ; involucre cupular, obliquely 
inserted at the base of the spathel above its own into which it is half immersed, 
obsoletely bidentate on the side next to the axis. Male flowers perfectly bifarious, 
inserted at an angle of 45°, not in contact with one another, glabrous, ovoid- 
oblong, obsoletely trigonous and obtusely subapiculate when not yet open; calyx 
cupular, subcyathiform, strongly striately veined, deeply parted into 3 broadly 
triangular acute loves; the corolla striate, twice as long as the calyx. 
HaBrrAr.— In the forests, at about 900 m. above the level of the sea along the 
Noori-river in the south part of Dutch New-Guinea, collected by Dr. G. Versteeg 
the 9th September 1908 (No. 1701 in the Utrecht Herbariam. ; collected again during 
Dr. Lorentz’s expedition in 1909 by M. Von Romer on Mount Hellwig, botwdii 1350 
to 1600 m. above the level of the sea. 
OsskRVATIONS.— This is a very characteristic delicate species easily distinguishable 
from any other known to me by the leaves of the upper part of the plant having 
no petiole and having many very regularly set leaflets, which bear on 3 nerves 
above and on the margins very long soft bristles far longer than those of (. ciliaris,
