spathas primarias anguste vaginantes, superne scariosas, extus brcvitei 
spmulosas onentibus. Spathae secundariae inermes, angustissime vaginantes. 
superne dilatatae, scariosae, oblique truncatae, ramulos basi pedunculiformes 
flonbus distichis ca. 20 in quoque latere nascentes. Spathulae infundibuli- 
formes involucrophorum pedicellatum inferne anceps suffiilgentes. Fructus 
parvus, ovoideo-ellipticus, utrinque aequaliter rotundatus, minutissime rostra- 
tus, squamuhs 18-seriatis, convexis, stramineis, tenuiter longitudinaliter 
carinatis, apice obtusis loricatus. 
A large climber. Leaf-sheaths . . . Leaves large, terminating into 
a long and robust cirrhus regularly armed with */ 4 whorls of strong black- 
tipped claws; rachis with upper salient angle smooth, armed beneath at 
regular distances with black-lipped at first solitary then 2—3 and finally 
half-whorled robust claws; leaflets very numerous equidistant 3—4 cm apart 
on each side of the rhachis, papyraceous linear-lanceolate, concolour and 
almost shiny on both surfaces, very narrowly polished along the lower 
margin, gradually long-acuminate to a fine subulate tip, tricostulate, side 
'■oslae slender, the 3 costae in the upper surface sparingly bristly spinulous 
underneath not prominent and also more or less bristly, bristles longer on 
the mid-costa; transverse veinlets very faint; margins minutely and closely 
and appressedly spinulous; the lower and larger leaflets 40 cm long and 
2 cm broad; the upper gradually shorter, not narrower, only those nelr the 
cirnus smaller in breadth and length. Male spadix . . . Female spadix 
large, non flagelliferous at its summit, much branched and forming a large 
i il use panicle composed of several partial inflorescences. Primary spathes 
u ular, slightly enlarged above, closely sheathing, often split longitudinally, 
on t e inner side coriaceous, withered in their upper part, armed with 
small prickles having swollen and often confluent bases and transversedley 
seriah', partial inflorescences arched-spreading inserted. With elongate 
pedicellar part inside their respective spathes, the largest 60—70 cm Ion'’ 
with 8 10 spikelets on each side; secondary spathes very closely shea- 
nn r , tubular slightly enlarged above, obliquely truncate at the mouth 
an prolonged at one side into a triangular point, unarmed, frequently 
split longitudinally, withered above, the withered or dry part forming a 
n-oad ring around their mouths; spikelets inserted with a flattened pedicellar 
part to the bottom of their respective spathes arched-spreading, the lowest 
and largest 10-12 cm long with 20—22 distichous flowers on each side- 
spathels briefly and not very broadly infundibuliform exactly truncate at 
the mouth obsoletely apiculate at one side; involucrophorum unilaterally 
subinfundibuliform, narrowed to the base and therefore distinctly pedi- 
cella le, not exceeding its own spathel and attached to its bottom, twokeeled 
on the side next to the axis; involucre rather deep obliquely cupular, 
slightly produced on the side of the areola of the neuter flower, which is 
mche-hke somewhat vertically evolute and sharply bordered. Female
