C. asperrimus.) BECCARI. MONOGRAPH OF THE GENUS CALAMUS. 423 
deflexed; involucre transversely evolute, sublunate and apparently formed by two 
semiovate slightly faleate bracts—connate by their bases; spathels and involucra 
membranous, reddish-brown, strongly striately veined, ciliate and sprinkled with small 
rusty subhairy scales. Male flowers 4 mm. long, oblong; the calyx parted to about 
midway down into 3 broadly triangular acute distinctly bordered lobes, strongly 
striately veined; the segments of the corolla twice as long as the calyx, opaque 
and finely striate outside. Female spadiz simply decompound, about 1:8 m. long 
(Blume), nodding, slender, with 7-9 partial inflorescences and terminating in a rather 
elongate aculeolate filiform appendix; primary spathes . . . . .; partial inflores- 
cences elongate with straight slender axis, the one seen by me 40 cm, long with 18 
distichous spikelets in all; secondary spathes tubular, slightly infundibuliform, 2°5-3 
em. long, obliquely truncate and densely bearded at the mouth, scabrid; spikelets 
inserted just at the mouth of their own spathe, horizontal, slightly arched, the lower 
ones, the largest, about 4 cm. long, with 8-10 distichous very approximate flowers 
on each side; the upper ones somewhat shorter; spathels very closely packed, sub- 
perfoliate or with a very short tubular part, suddenly expanded into a very broad 
concave bracteiform obtuse deflexed limb; involucrophorum and involucre subconform, 
bracteiform, concave, unilaterally evolute in contrary directions; spathels and involuera 
strongly striately veined and glabrous inside, densely ciliate and covered outside with 
rusty-paleaceous hairs; areola of the neuter flower depressed, linear, hidden under the 
involucrum. Female flowers about 4 mm. long, almost horizontally inserted; the calyx 
subcoriaceous, striately veined outside, parted to midway down into 3 very broad 
semiovate rather obtuse distinctly bordered lobes; segments of the corolla narrower 
but as long as the lobes of the calyx. Fruiting perianth apparently not or very 
shortly pedicelliform. Fruit (very young) ovoid, tapering to a stout conic beak; 
scales shining, in 18-20 series, reddish-brown at the summit, this not fringed an’ 
erosely toothed at the margins. 
HanrrAT.—On the volcanic mountains of Java, such as the Megamendong, Pan- 
gherango, Gedé, etc., Blume.—Javan name: “ Huy Lulus” or “H. Leles”; Malayan 
name: ‘ Rotang Lumus." 
OnsrRvaTIONS.—Biume founded this species only on specimens of the female plant 
with spadices bearing very young fruit. Of Blume's specimens I have seen some 
portions of which I availed myself in the description above. Furthermore I have 
recognized this species in some fine eultivated male specimens forwarded to me from 
Buitenzorg by Dr. Treub and in others (also with male spadices) sent by Teysmann 
to the St. Petersburg Herbarium. These last have a leaf with a very long cirrus, 
the leaflets are 11 on each side, of which the largest is 25 cm, long and 27 mm. 
broad; some of them are subtricostulate, having on each side of the mid-costa one 
secondary nerve slightly stronger than the others. The sheathed stem in Blume’s 
specimen is 2 cm. in diam. and in the cultivated male specimens is a good deal 
more slender (6-12 mm.). In these the leaves of the lower part of the plant are 
not cirriferous, have 28-30 leaflets in all, with the two of the terminal pair free at 
the base; the leaves of the intermediate portion have a very slender and rudimentary 
cirrus at their summit, and the uppermost are conspicuously cirriferous; these last have 
9-10 couplets of leaflets 15-20 em. long and 15-18 mm. broad, :
