104 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. Winklerianus. 
" half-whorls of rather delicate, very sharp, black-tipped claws; petiole very short, 
or almost obsolete ; the rachis in its lowest part is about 5 mm. broad, depressed, 
with the upper surface flat, the lower convex, and the edges obtuse; higher 
up it becomes bifaced on the upper surface with the salient angle smooth; the 
lower surface is rather irregularly armed, especially on its lower portion, with 
rather robust claws. Leaflets not very numerous (19-13 on each side’, very 
inequisdistant, often approximate in pairs on each side of the rachis, with rather 
long vacant spaces interposed between the pairs; they are papyraceous, rigidulous, 
glabrous, dull, concolorous, and of a greenish-yellow colour (when dry) on both 
surfaces: those near the base are linear, very narrow bot larger towards the upper 
end: the mesials (largest) are narrowly oblanceolate, or very narrowly spathulate, 
plicately 5-costulate, 16-22 cm. long, 20-23 mm. wide in their broadest part (above 
the middle, or not very far from the apex) and thence gradually taper down to 
an acute base: their upper ends are suddenly narrowed into a more or less 
produced narrow acuminate mucro or tip, which is quite bald or has 1-2 subspiny 
(deciduous?) bristles at its apex, the costae slender and smooth on both surfaces; 
transverse veinlets fine, much interrupted, margins perfectly smooth. Male spadiz 
about 80 cm. long, covered with a thin rusty-furfuraceous, removable, and partly 
deciduous indumentum, springing erect from about midway of the sheaths, then 
nodding, not flagelliferous at its apex, which terminates in a slender tail.like 
appendage,  ultra-decompound or at times almost simply decompound, with 10-11 
partial inflorescences; primary spathes 6-7 cm. long: the lowest not longer than the 
others, tubular, slightly infundibuliform or somewhat enlarged and rather loosely 
sheathing in their upper part, armed more or less on the back with short claws, 
narrowed to the base into a short smooth axial part, which is concave on the 
inner and convex on the external side, obliquely truncate, bearded or very densely 
ciliate at the mouth with long, light-coloured hairs, and produced at one side into 
a lanceolate-acuminate, and also bearded point; partial inflorescences inserted at the 
mouth of their own spathes, spreading and arched: the lower are 12-15 cm. long 
and have several compound spikelets on each side: the upper gradually smaller; 
secondary spathes elongate-infundibuliform, unarmed, covered with rusty-furfuraceous 
scales, obliquely truncate and conspicuously ciliate at the mouth, prolonged at one 
side into a rather acute tip; the primary, or compound spikelets are spreading, arched 
or subscorpioid ; those of the lower part of the partial inflorescences are 2-4 cm. 
long, and carry 8-10 gradually diminishing secondary spikelets on each side; in 
the upper part the spikelets are gradually smaller; at times the partial inflorescences 
bear only a few compound spikelets in their lower part and all the others are 
simple; the secondary spikelets are very small, 3-5 mm. long, circinate-scorpioid» 
and have 3-5 very closely packed flowers on each side; spatheis very approximate, 
bracteiform, concave, broadly ovate, acute or acuminate, strongly deflexed and 
subtending their flowers; involucre slightly concave, transversely evolute and 
apparently formed by two triangular, divaricate, acute bracts connate by thei, 
bases; spathels and involucra reddish-brown, ^ scaly-furfuraceous, strongly striately 
veined, and ciliate, Mule flowers small, 2 mm. long, ovoid subtrigonous ; .the calyx 
briefly subcampanulate, strongly striately veined, parted midway down into 3 very 
broad acute lobes; the corolla about twice as long as the calyx, dull . outside,
