Q. javensis] BECCARI, MONOGRAPH OF THE GENUS CALAMUS, i 177 
truncate at the mouth, distinctly striate longitudinally, quite unarmed. Ocrea very 
short, almost obsolete. Zeaf-sheath flagella filiform, very slender, finely aculeolate 
callous at the base, Leaves simple, not pinnate, 45 cm. long, 10 cm. brosi, 
elongate-flabelliform, papyraceous, green, of the same colour on both surfaces prada 
ally attenuate and acute at the base, furcate or divided in the upper third bust Gt their 
length into two broadly lanceolate, acuminate, acutely 6-7-costate lobes; the doei 
very acute, naked on both surfaces all of the same strength and all reaching the 
apex, and lower down meeting at different heights and at a very acute angle along 
the mid-costa of the blade; beneath, the mid-costa (or rachis) rather robust and 
sparingly clawed; margins acute, not ciliated or spinulous; transverse  veinlets 
rather approximate and sharp; petiole 3-4 cm. long, slender, sub-trigonous, striate, 
unarmed.—Other ports unknown. 
Hasirat.—Borneo; on Mount Mattang, near Kuching in Sarawak (Beccari 
P. B. No. 1911.)— The Rotang is of very good quality and is called in Sarawak 
Rotang Berman. | 
OssERvATIONS,— The only specimen I have preserved of this-very peculiar Calamus 
is sterile, but it belongs to a nearly full-grown plant. Other species have undivided 
or furcate radical leaves, but this is the only one I know with furcate or flabellate 
leaves on the upper part of the stem. Its affinities are apparently with the species 
of the group of C. javensis,

Description.—Scandent, slender. Sheathed stem 5-8 mm. in diam. Leaf-sheaths 
distinctly striate longitudinally, green, glabrous, sparingly armed with straight 1-5 mm, 
long, solitary, horizontal or slightly deflexed spines. Leaf-sheath flagella with the 
lowest spathe usually smooth. ^ Ocrea 5-12 mm. long, ciliate, maked or fugaciously 
furfuraceous. Leaves short, 30-50 cm. long; potiole very short or almost obsolete ; 
leaflets very few, 3-6 on each side, more or less inequidistant, usually opposite 
or subopposite, oblong-lanceolate or lanceolate-elliptic,  cuspidate, rather variable 
in size and in relative breadth, with 3 often spinulous coste; the two 
leaflets near the base smaller than the others and spreading, the two of the 
terminal pair two-thirds connate. Male and female spadiz as in var. peninsularis. 
Fruit 15-16 mm, long (including the beak), 9-10 mm. in diam., ellipsoid-ovoid, with -
