386 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. LC. andamanicus. 
nerve and rather distantly  bristly-ciliate. Male spadiz large, shorter than the 
leaves, in one specimen 1:25 m. long, panicled, rather dense, with not very 
numerous approximate partial inflorescences; primary spathes rather short, 8-10 cm. 
long in the exposed part, tubular, slightly enlarged above, closely sheathing, the 
lower ones slightly compressed, the upper ones more cylindraceous, thinly coriaceous, 
often longitudinally split but not lacerated, more or less sparsely armed (especially 
on the back) with short small solitary or confluent prickles, obliquely truncate, 
entire and naked at the mouth and prolonged at one side into a dorsally keeled 
triangular acute point; partial inflorescences inserted at the bottom of their own 
spathe with a long pedicelliform part; the lower ones, the largest, up to 80 cm. 
long with 7-8 gradually diminishing secondary inflorescences on each side: secondary 
spathes tubular-cylindraceous, slightly infundibuliform, unarmed, almost horizontally 
truncate, shortly apiculate at one side, glabrous, thinly coriaceous, entire or longi- 
tudinally split but not lacerated; secondary inflorescences ascendent, stalked and 
inserted inside their own spathe; the lower ones, the largest, 15-20 cm. long with 
15-20 spikelets on each side; tertiary spathes tubular-infundibuliform, acute at one 
side; spikelets inserted at the bottom of their own spathe, with a distinct flattened 
pedicel; the lower ones, the largest, 20-25 mm. long, often arched, with 15-20 very 
crowded  bifarious flowers on each side; spathels very, closely packed, concave 
subcymbiform with a round obtuse or apiculate point; involucre shorter than the 
spathels, cupular, deep, entire truncate, two-keeled on the side next to the axis. 
Male flowers small, 3 mm. long, obovoid, rather obtuse, furfuraceous at the summit 
like the spathels; the calyx campanulate, slightly narrowed to the base, finely 
‘inconspicuously striately veined, divided down almost to the middle into 3 broad 
and at the summit rounded lobes; the segments of the corolla one-third longer than 
the calyx, concave, lanceolate, externally opaque. Female spadiz simply decompound, 
panicled, shorter than the leaves, not flagelliferous at its summit, in one specimen 
about 1 m. long with many approximate partial inflorescences; primary spathes as 
in the male spadix, but much more densely armed with short subseriate reversed 
prickles, the lower ones slightly differing from the others; partial inflorescences 
stalked as in the male spadix, the lower ones, the largest, 50-60 em. long with 
8-11 distichous spikelets on each side; secondary spathes as in the male spadix, 
but sometimes very sparingly prickly, ultimately decayed in their upper part, but not 
lacerated ; spikelets attached to the bottom of their own spathe and stalked, spreading, 
slightly arched, the lower ones, the largest, 10-15 cm. long, the upper ones some- 
what shorter; spathels shortly infundibuliform, horizontally truncate and entire at 
the mouth, obtuse and not or very slightly prolonged on the. exterior side; 
involucrophorum calyciform, inserted at the bottom of its own spathel, narrowed 
to the base and therefore subpedicellate, acutely two-keeled on the side next to 
the axis; involucre cupular, exceeding the involucrophorum, irregularly cupular and 
unilaterally evolute; areola of the neuter flower elliptic, concave, sharply bordered. 
Female flowers about 6 mm. long, the calyx dusty-furfuraceous, divided into 3 ovate 
lobes; the segments of the corolla ovate-lanceolate, acute externally, opaque, finely 
striate and about as long as the calyx; filaments of the stamens very broad, 
connate by their base, very suddenly apiculate; abortive anthers small. Fruiting 
perianth not forming a pedicel and split under the fruit. Fruit ovoid-elliptic or 
slightly obovoid, conically beaked and acute at the apex, about 18 mm. long and
