shiny on both surfaces, rather distinctly 3-costulate, mid-costa very sparingly 
bristly spinulous only near the apex in the upper-surface; the 3-costae 
underneath feebler and only that of the middle obsoletely spinulous; mar- 
gins very minutely remotely and appressedly spinulous; spinules more 
numerous and distinct in the apical part; transverse veinlets inequal not 
very sharp and pellucid, lowermost leaflets (in a portion of a leaf seen 
by me consisting of its apical part 80 cm in length) 45 cm long, 23 mm 
broad; this upper ones gradually shorter, the two terminal being the 
smallest and quite free at the basis. Male spadix ... Female spadix 
straigt, rigid and rather elongate (not flagelliform) terminating into a rudi- 
mentary cirrus and divided into several gradually diminishing superposed, 
distant, partial inflorescences; primary spathes elongate-tubular, closely 
sheathing in their lower part, produced above into an elongate, dry, mem- 
branous, lacerate limb, covered with a minute rusty scurf and densely 
beset with small short prickles having a bulbous light coloured base; par- 
tial inflorescences inserted inside their respective spathes, not long-pedicelled, 
rather dense rising erect from the leafsheaths and slightly arched above; 
the lowest inflorescence in the portion of spadix seen by me 18 cm long 
with 7—8 gradually diminishing spikelets on each side; those above speedy 
smaller with considerably fewer spikelets; secondary spathes infundibuli- 
form, truncate, ciliate at the mouth, rusty scurfy and very densely beset 
with minute prickles, like those covering the primary spathes but smaller; 
spikelets inserted just above the mouths of their respective spathes with 
a distinct axillary callus, spreading and arched subscorpioid, the lowest of 
every partial inflorescence 5 cm long with two series of 8—9 biserious 
very slightly assurgent not flatly bifarious flowers; upper spikelets gradually 
smaller, the uppermost very short with very few flowers; spathels very 
briefly infundibuliform, covered with the same kind of minute prickles as 
the secondary spathes; involucrophorum short, cupular, placed just at the 
base af its own spathel, involucre orbicular shallowly cupular; areola of 
the neuter flower lunate callous. Fruiting perianth briefly pedicelliform. 
The very young fruit obovoid with very stout beak, scales in 21 vertie 
series, convex subsquarrosa, yellowish in their posticous part, and with 
red-brown margins and point.

I have seen the upper part of a leaf only änd a few pieces of the female spadix 
with very young fruits. The collector notes only »hochkletternder daumendicke"

leaf-sheaths have a long or a rudimentary flagellum. It belongs to group Y wie
