Description.—-Scandent or standing?  Sheathed stem 3-6 cm. in diam. (1-2 in. 
Miquel . Leaf-sheaths flagelliferous, thick, pale, striate, glabrous, obliquely truncate and 
sparsely hairy at the mouth, strongly armed with straight, subulate, usually more or 
less confluent and whorled, brown-yellowish or chestnut-brown spines, of which the 
largest about 3 cm. long, these intermingled with much smaller ones. Leaves 
subcirriferous ; petiole short, 16-22 cm. long (6-8 in. Miquel), and about 14 mm. 
thick (5 in. Miquel), rounded and strongly spinous below, especially at the margins; 
the pinniferous part 1-1:9 m. long; rachis in its upper portion acutely bifaced above, 
round beneath where armed with deflexed solitary or more often 3-nate prickles of 
which in this last case the mesial very long; leaflets numerous ( about 50 on each 
side) inequidistant and fascicled in groups of 5-6 (on each side of the rachis ?, 
Beccari ), linear-lanceolate, acute, all similar, 16-22 or at most 24 cm. long (6-8 or 9 
in. Miquel) and 11-14 mm. wide (5-6 lines Miquel), shining above, uni- or subtri- 
costate with the mid-costa acute and furnished with erecto-patent, brown, bristly 
spinules, the side costae more slender and sparingly spinulous; margins spinulous- 
serrate; in some very adult leaves the leaflets are more rigid and subseptemnervous ; 
apical leaflet, narrower than the others, a few inches long, aculeolate. ^ Leaf-sheaths 
flagella inserted near the mouth of the sheath, very long, armed with very acute 
black-tipped ternate claw. Spadiz ( male?, Beccari), very long, with 5-6 partial 
inflorescences; these bearing 5-10 alternate spikelets; primary spathes rather loosely 
sheathing, with tubular, somewhat flattened, lanceolate limb; secondary spathes tubular, 
short, striate; spikelets 5:5-8 cm. long; spathels striately veined, asymmetrically 
infundibuliform; involucre (spathellule, Miquel), cupular, bidentate. Flowers (male, 
Beccari) rather remote, conic when in bud; calyx 3-toothed; corolla divided into 3 
elongate narrow segments, (Description from Miquel, |. c.) 
Hasrrar.—South Borneo ( Miquel). 
OssERvATIONS.—I have seen no specimens of this. I do not know auy other 
Calamus with long flagelli at the sheaths and the leaves subcirriferous at the summit, 
and at the same time with fascicled narrow sub-3-costate leaflets. The combined 
character of the linear-lanceolate fascicled leaflets with the rachis armed beneath with 
ternate deflexed spines, of which that of the centre is long, is peculiar to C. viminalis ; 
but in this the leaves are not subcirriferous at their summit. The stem also is 
apparently described as being erect, about as high as a man, but a full-grown 
species of Calamus with standing stem and at the same time with flagelliferous leaf- 
sheaths is not yet known. For these reasons I consider €. pulcher as a doubtful 
species, probably founded upon heterogeneous elements.
