334 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. pilosellus. 
solitary prickles; rachis armed beneath along the middle (like the petiole) with solitary 
claws, these becoming closer and. smaller towards the apex, bifaced and acute 
above -and covered with a ferrugineous down, and furthermore finely tubercled-scabrid 
owing to the bases of the rusty hairs with which it is clothed; leaflets numerous 
(35 pairs in one leaf), equidistant, 10-12 mm. apart, very regularly inserted at an 
angle of about 45°, alternate or almost opposite, narrowly lanceolate, almost equally 
parrowed to both ends, acuminate at the summit, thinly papyraceous, rather firm, green 
and subconcolorous on both surfaces, with the acute mid-costa and 2-3 secondary 
nerves on each side of it furnished with long fulvous bristles on the upper surface, 
where furthermore on the very slender tertiary nerves are longitudinally arranged 
numerous very minute and short bulbous hairs; on the under surface the mid-costa 
and the secondary nerves are indistinet and the very numerous (about 50) and very 
slender tertiary nerves are closely covered with excessively minute and short bulbous 
hairs, which render that surface scabrid to the touch and are almost invisible to 
the naked eye; margins rather closely ciliated with fine long fulvous erecto-patent 
hairs; transverse veinlets few, distant and short, not very conspicuous; the largest 
leaflets, the mesial, 10 cm. long, 10-11 mm. broad, acuminate to a capillary point, 
the lowermost smaller and narrower, the upper ones a trifle smaller but less. acu- 
minate and with a bristly-hairy tip, the two of the terminal pair free at the base. 
Male spadiz slender, elongate, rigid, erect, in one specimen 1 m. in length, including 
the terminal filiform flagellum, glabrous, smooth, and not hairy-scabrid in any part, 
ultradecompound, with 5 partial inflorescences; primary spathes elongate, tubular, closely 
sheathing, obliquely truncate, entire and naked at the mouth, where prolonged at 
one side into a short point; the lowermost unarmed, somewhat flattened, rather 
acutely two-edged, the upper ones cylindraceous, sparsely aculeolate on the dorsal 
side near their base; partial inflorescences panicled, lax, the lowest, the largest, 13 
em. long, inserted at or a little above the mouth of their respective spathes, with 
a distinct axillary callus and transverse rima, ascending at first, then arched and 
scorpioid, with a few branchlets near the base and some very slender spikelets in 
their upper part; the upper inflorescences with only 3-4 spikelets on each side, of 
which the lowermost barely branched and the upper ones very short and very few- 
flowered; secondary spathes unarmed, glabrous, tubular, very slightly enlarged above, 
closely sheathing, prolonged at one side into a triangular acute or acuminate point; 
spikelets (like the branchlets) inserted above the mouth of their own spathes, with a 
distinct axillary callus, patent, arched downwards and subscorpioid; the largest, the 
lowest, 15-20 mm. long with 8-10 alternate remote  biseriate assurgent flowers; 
the other spikelets gradually shorter, the uppermost with 2-3 flowers only ; spathels 
elongate, tubular, closely sheathing, slightly enlarged above or narrowly in- 
fundibuliform, subscarious in their upper part, prolonged at one side into a 
triangular acute point; involucre discoid or pateriform, circular or obsoletely trigonous, 
slightly concave or almost flat, inserted outside its own spathel at the base of the 
one above, with a distinct axillary callus next to the axis, more or less supported 
by a thick short pedicel or neck.—WMale flowers, female flowers and fruit unknown.
