388 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [¢C. Zollingerii. 
one I measured 4'5 m, in the pinniferous portion); the cirrus very robust, armed 
with i-whorls of very strong black claws; petiole very robust, 3-3:5 em. broad, 
deeply channelled above, round beneath where irregularly armed with straight strong 
unequal spines; rachis in its lowest portion broadly channelled above, rounded 
beneath, where armed along the middle with solitary claws and elsewhere with 
scattered prickles; higher up sub-4-angular in section but roundish beneath, and 
more or less channelled above, with spinulous margins, and with rather broad side-faces 
where are inserted the leaflets; in the terminal portion trigonous, bifaced above and 
strongly armed beneath with robust 3-5-fid half-whorled claws; leaflets numerous, 
equidistant, 3-4 cm. apart, papyraceous, ratner rigid, large, ensiform, the largest, the 
intermediate ones, 50-70 em. long, 3-3'5 em. broad, the upper ones s:maller and more 
distant, gradually acuminate at the apex, suddenly sonteaored and plicate at the base, 
green on both surfaces; the mid-costa prominent, acute and naked or nearly so above 
where accompanied on each side by a slender nerve, this furnished with a few long 
bristles; in the lower surface the mid-costa barely prominent, but furnished with a 
few 2-25 cm. long bristles; the side-nerves faint and smooth; margins remotely 
spinulous-setose, somewhat thickened by an intramarginal nerve. Male spadiz not seen 
entire, but apparently large and much branched; partial inflorescences (only one seen) 
panicled, compact, cupressiform, divided in its lower part into many approximate 
secondary branches or compound spikes and bearing upwards some simple spikelets; 
these much larger than the secondary ones of the lower branchlets ; primary spathes 
not seen; secondary spathes tubular-infundibuliform, 2-4 cm. long, closely sheathing, 
papyraceous, obliquely truncate at the mouth, unarmed, prolonged at one side into a 
triangular acute point; the lowest compound spikes, the largest, 7-8 cm. long, inserted 
inside and at the bottom of their respective spathe, 7-8 cm. long; spikelets 6-7 on 
each side of the secondary axis, approximate, about 1 cm. in length; spathes of the 
compound spikes broadly infundibuliform, truncate, finely striately-veined, extended at 
one side into a short triangular point; spathels of the simple spikelets very closely 
packed, bracteiform or boat-shaped, finely striately-veined, very obtuse; involucre 
cupular, apparently formed by two bracts, more or less connate by their bases, or 
sometimes nearly disjunct and ovate, acute, concave, acutely keeled next to the axis. 
Male flowers (in bud) oblong obtuse, 4 mm. long, the calyx entirely split into 3 oblong 
thinly pergamentaceous, finely striately-veined, concave, rather obtuse parts; corolla 
twice as long as the calyx, divided down to a little beyond midway into 3 ovate- 
elliptic, finely striate segments; filaments of the stamens subulate, inflected at the apex, 
united at the base with the undivided tubular-infundibuliform part of the corolla, longer 
than the segments; anthers linear-sagittate acute; rudimentary ovary formed by 3 small 
distinct acicular bodies, about as long as the tube of the corolla. Female spadiz 
very large but relatively short (1-1-5 m.) non-flagelliferous at its summit and forming 
a rather dense pyramidate cupressiform panicle, composed of many approximate partial 
inflorescences; these 50-50 cm. long, terminated by a very short tail-like appendix 
and bearing 8-14 spikelets on each side; primary spathes relatively short, 10-20 em. 
long, tubular-cylindraceous slightly enlarged above, closely sheathing, more or less 
covered with scattered tuberculiform spines and prolonged at the summit into a 
withered iriangular acuminate point; secondary spathes as in the male spadix, often 
longitudinaliy split in the fruiting stage; spikelets inserted inside their own spathe 
and conspicuously pedicellate, ere at first, then spreading, the lowermost 8-10.
