most, ending in a very slender smooth filiform appendix; primary spathes exces- 
sively narrow, very strictly sheathing, cylindraceous throughout, obliquely truncate at 
the mouth and produced at one side into a short triangular or lanceolate point; 
partial inflorescences very few (2-3), very distant and very delicate, lax, sproadinis 
10-12 cm. long, with very few (4-6 in all) spikelets; secondary spathes strictly 
sheathing, tubular, slightiy clavate, smooth, obliquely truncate and naked at the 
mouth, obsoletely apiculate on one side; spikelets filiform, zig-zag sinuous, 1:5-3 cm, 
long, horizontally inserted above the mouth of their own spathe, conspicuously 
callous in their upper axilla, with very few (2-3) flowers on each side; spathels 
tubular, uncommonly elongate, slightly enlarged above, strongly  striately veined, 
truncate and apiculate at one side at the mouth; involucrophorum laterally attached 
to the base of the spathel above its own, shallow and irregularly cupular with an 
axillary callus next the axis; involucre irregularly cupular, strongly veined; areola 
of the sterile flower rather large and more or less depressedly lunate, Female flowers 
very small (hardly 2 mm, long), relatively very remote (3-4 mm. apart) Fruiting 
perianth not pedicelliform, its calyx split almost to the base into 3 very broad 
apiculate lobes, these slightly shorter than the segments of the corolla. Fruit very 
small (immatare 6 mm. long), broadly ovate with a conical top; scales in 12 series, 
shining, convex, not channelled along the middle, light-yellowish, bordered by a 
broad chocolate-brown band which extends to the erosely toothed tip. Seed not 
seen perfectly ripe.

OssERvATIONS.— This is perhaps the smallest species of the genus; though nearly 
stemless and devoid of the usual organs of climbing, the very slender and long 
spadices raise themselves amongst the shrubs by means of the small divaricate 
spikelets acting as rigid hooks.

DeEscRIPTION.—Scandent, sheathed stem as thick as a finger. Leaf-sheaths flagelli- 
ferous, not gibbous above (always?), gradually passing into the petiole, covered with 
a grey ochraceous scurf when young, open upwards on the ventral side, where densely 
covered near the margins with long erect rigid bristles of a reddish-brown colour, 
these intermingled with some slender subulate spines; the remainder (the greatest part)
