344 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. CC. Bousigonii. 
with small numerous scattered horizontal or slightly deflexed dark-brown fine subulate 
spines which rest on a swollen base and are about 1 cm. long at most and some- 
times almost tuberculiform.  Leaf-sheath flagella filiform, elongate (1:5 m.) compressed 
in their lower portion where acute and aculeolate on the margins, armed upwards 
with simple or 3-nate claws. Ocrea very short, obliquely truncate. Leaves relatively 
short, 75-85 cm. long, not cirriferous, with very few (11-13 in all) leaflets; 
petiole 15-20 cm. long, flattish above, rounded and clawed beneath, the margins 
armed near the base with straight spines; rachis bifaced above in its upper portion 
and sparsely clawed below; leaflets remotely inequidistant, irregularly alternate, sub- 
ovate-rhomboid, cuneately attenuate, symmetric and acute at the base, shortly and 
suddenly acuminate at the summit into a bristly tip, papyraceous, rather firm, quite 
glabrous, opaque, green, and with a few brown polished longitudinal stripes on both 
surfaces, slightly paler beneath with 5-7 radiately divergent naked (not bristly or 
spinulous) costae of which the mid-costa only reaching the summit and the side ones 
arched near the margins and evanescent at different levels; secondary nerves slender; 
transverse veinlets sharp, numerous, approximate, continuous and subparallel; margins. 
slightly undulate from the middle upwards, bristly-spinulous near the summit; some 
of the largest lezflets 20 cm. long, 8°5 cm. broad; in one leaf the intermediate ones 
15 cm. long, 6 cm. broad; the upper ones slightly smaller; the two of the terminal 
pair quite free at the es: 9-10 cm. long, 3 cm. broad. Male spadix . : 
Female spadiz flagelliform, not very elongate, straight (not seen entire) and rigid. in 
its lower portion with few partial inflorescences; primary spathes tubular, elongate, 
closely sheathing, obliquely truncate at the mouth, strongly and densely spinous, the 
spines straight, similar to those of the sheath or in the upper spathes, somewhat 
hooked; partial inflorescences short (8-10 cm. long) erecto-patent with few spikelets; 
secondary spathes tubular, short, truncate, unarmed; spikelets 1:5-2:5 cm. long, slightly 
arched, spreading, with few (8-10) somewhat irregularly not flatly biseriate flowers; 
spathels shortly and broadly infundibuliform, 2-3 mm. long, narrowed to the base, 
glabrous, striately veined, entire and truncate at the mouth, acute at one side; 
involucrophorum sessile, concave, very shallow, laterally attached to the base of the 
spathel above its own; involucre cupular, obsoletely bidentate on the outer side > 
areola of the neuter flower broadly lunate, sharply bordered. Female flowers 4*5 mm, 
long, the calyx very broadly 3-toothed; the corolla one-third longer than the calyx, 
its segments ovate-lanceolate, rather obtuse, almost polished outside or indistinctly 
striately veined; staminal urceolam crowned by 6 triangular teeth. Fruiting perianth 
shortly pedicelliform. Fruit broadly ovoid, very suddenly beaked, about 18 mm, 
long, 14 mm. broad; scales in 18 series, broader than long, almost flat, very 
slightly chauneiled along the middle, subshining, straw-yellow, narrowly bordered with 
chestnut-brown, the point obtuse, the margins erosely toothed. Seed ovoid-oblong, 
rounded at both ends, about 1 cm. long, 7-8 mm. broad, covered with a very thin 
adherent integument, superficially and coarsely pitted all round; the chalazal fovea 
very shallow and small, above the centre on the raphal idi: ; albumen bony, 
‘superficially ruminated ; embryo basal.
