confluent and subseriate. Koorders’ specimens exactly agree with the typical ones 
and like these have the leaflets subochraceous on the under surface.

DEscRIeTION.—Scandent and large. Sheathed stem... Leaf-sheaths..,......Leaves large; 
leaflets equidistant, very regularly set, 3-3'5 cm. apart, narrowly ensiform (those seen 
by me apparently belonged to the intermediate portion of the rachis) 73 em. long, 
29-5 cm. broad, narrowing a little towards the base, and very gradually long acuminate 
from below the middle to a subulate and at the sides finely ciliate tip; they are. 
almost glossy above, dull and slightly paler underneath, rather firmly  papyraceous, 
very distinetly 3-costulate, or even 5-costulate, for besides the 3 costae, which are very 
prominent on the upper surface, a secondary rather distinct nerve runs in very close 
proximity to each margin; tranverse veinlets very numerous and fine and like the 
costae, more distinct on the upper than on the lower surface; the mid-costa is con- 
siderably stronger than the side costae, and on the upper surface is very sparingly 
bristly-spinulous but only near the apex, while one of the costae on each side of it 
is furnished with long fulvous bristles; underneath the side costae are smooth, 
and the mid-costae conspicuously bristly; margins distinctly and spreadingly ciliate. 
Male spadiz....Female spadiz apparently large and elongate, and probably provided 
with a long terminal clawed flagellum, but the specimen seen by me consists 
of only a partial inflorescence with a portion of the axial part; the latter is robust, 
obsoletely angular, 6-7 mm. thick, very powerfully armed externally with small rows. 
of 3-4 confluent, very robust, black, broad-pointed claws; the partial inflorescence 
has a generally scorpioid aspect and is 33 em. long; its axial part is strongly arched, 
rigid, terete, 6 mm. thick at the basə and generally narrows towards the upper 
end; it has 6 spikelets on each side, but with a unilateral tendency and terminates in 
a tail-like apex, which carries alternate single flowers. Secondary spathes tubular, 
very closely sheathing, unarmed, glabrous, smooth (not striately-veined) obliquely. 
truncate and smooth at the mouth, produced at one side into a triangular acute or 
acuminate point; spikelets inserted above the mouth of their respective spathes, 
arched, spreading or recurved, with their axial part terete, 2:5 mm. thick; the 
lower and largest spikelets are 9-10 cm. long and have 10-12 flowers on each side ; 
spathels tubular, cylindrical, closely sheathing,  horizontally-truneate, and naked at 
the mouth, briefly apiculate at one side. The flowers (female) 7-8 mm. apart on 
each side, borne by a distinct thickish neck-like or pedicelliform involucrophorum, 
attached to about the middle of the spathel above its own, and having a distinct. 
axillary callus; it is about 2 mm. long, terete, and about 1:5 mm. thick at its base, 
but broadens slightly above into a short truncate limb; involucre exserted from the 
involucrophorum, discoid, flat, entire; areola of the neuter flower depressed. Fruiting 
perianth shortly but distinctly pedicelliform, terete, broader than high (8:5 mm. 
broad, 2 mm. high) formed by the tube of the hardened calyx, which has the limb 
irregularly split; the corolla about as long as the calyx, its segments triangular, 
smaller than the lobes of the calyx. Fruit spherical with a short and broadly 
conical beak, about 15 mm. in diameter; scales arranged in 18 longitudinal series,
