flower, of which the areola is distinctly lunate, sharply edged and callous in its 
centre. Female flowers 4-4'0 mm. long; the calyx shortly cylindraceous with a 
callous and flat base, smooth outside, divided down about to the middle into 3 
broadly triangular lobes; the corolla about twice as long as the calyx, its 
segments lanceolate, acute, smooth outside. The growing ovaries are elongated . 
into a thick style, whicn terminates in 3 relatively large, acute, internally lamellose 
recurved stigmas. Fruit ..... 
HasrraT,— The Malayan Peninsula. A species apparently very localized, discovered 
by Ridley in January 1904 on Gunong Pulai, in the State of Johore. (No. 12199 
in Kew Herbarium). 
Osservations.—I have seen of this species only a: leaf and an entire female 
spadix, with flowers spent and with growing ovaries. 
It is apparently related to ©. luridus, with which it partakes the not very 
common character of the corolla of the female flower being twice as long as the 
calyx; it differs chiefly in the leaves, which possess more numerous, more approxi- 
mate, but narrower, and less distinctly 3-costulate leaflets. Its diagnostic characters 
are: the (non-cirriferous) leaves with numerous, equidistant, linear-lanceolate, obscurely 
9-costulate leaflets, with minute spinules on the side costs above, and with very 
small hairs on the 3 coste beneath; the rachis armed beneath with a line of 
single claws; the female spadix rigid, relatively not very long, shortly flagelliferous 
at its apex, and with few rigid, 18—20 cm. long, partial inflorescences ; the spike- 
lets 3-45 cm. long, rigid, having closely-set bifarious flowers; the female flowers 
with an almost cylindrical calyx, smooth outside, truncate and callous at the base ; 
the corolla twice az long as the calyx, its segments lanceolate and acute; the ovary 
tapering to a relatively thick and large style, and with acute, recurved stigmas,

DescripTion.—Scandent, very slender. Shcathed stem 5-6 mm. in diameter. Leaf- 
sheaths bearing by turns spadices and flagella, thinly furfuraceous, when young very 
slightly gibbous above, sharply longitudinally striate, armed throughout with small, very 
slender, scattered ascendant, 2-5 mm, long, acicular spines; near the mouth the spines 
are more numerous and almost bristly and 10—20 mm. long or less, Oerea short, 
exsuccous, brittle, deciduous.  Leaf-sheath flagelia filiform, flattened in their lower part, 
densely armed all round in their very slender apical portion with excessively small 
solitary scattered claws. ^ Leaves non-cirriferous, very regularly pinnate; those of the 
lower part of the stem or of the young plants furnished with a elongate petiole 
and about 50 cm. long in the pinniferous part; those of the upper part of the 
florigenous stems much shorter, about 30 ecm. long and without a petiole; rachis 
flattish and puberulous underneath, bifaced above and bristly on the salient angle; 
the rachis of the radical leaves is unarmed underneath, that of the upper leaves is 
armed at regular distances ir its lower part, or even throughout to the apex, with 
very small, gradually diminishing claws; leaflets numerous, 35 on each side, regularly 
pectinate and equidistant, approximate (5-7 mm. apart) linear-lanceolate ; they
