i F DAEMONOROPS. 123 
D. didymophyllus] BECCARI. THE SPECIES O h 9 
The specimens now mentioned being both very incomplete and especially wanting 
in the spathes, do not allow of a rigorous comparison either with D. didymophyllus 
or with D. Motleyi, In conclusion, from what I can judge by the material I have 
examined, D. Motleyi is only a geographical form of D, didymophyllus.

DrscnrPTION,—Scandent, very variable in size, Sheathed stem 1:5-3 cm. and in 
very robust specimens up to 4 em. in diam. Leaf-sheaths obliquely truncate and usually 
without spines at the mouth, 
suleate or coarsely striate longitudinally, covered with 
a thin removable brown indumentum, irregularly armed with unequal, scattered, 
solitary or subseriate, laminar, broad-based, deflexed spines; the 
10 mm. broad at the base which is concave beneath, and 2 cm. 
long in. the pinniferous part, 
largest of these are 
long. Leaves 5 m. 
terminating in a somewhat slender, more or less 
elongate, angular, clawed cirrus; petiole 20-30 em. long, biconvex, somewhat flattened 
and with rather acute edges, more or less besprinkled above with short erect prickles 
and with often a few, long, straight, horizontal spines on the edges as well, usually 
less prickly underneath; rachis in its first portion more convex above than 
beneath, and with broad side faces for the insertion of the leaflets; higher up 
the salient angle becomes acute and is more or less spinulous throughout; under- 
neath, the rachis is armed with first solitary and then 3-5-nate half-whorled claws, 
especially on the cirrus; leaflets not very numerous (perhaps not more than 28-30 in 
all); those nearest to the petiole and the apices, solitary: all the others approximate 
‘in remote, sub-opposite or alternate pairs, the pairs 15-20 em. apart on each side of 
the rachis; the leaflets of each pair are almost in contact by their bases 
elliptical-lanceolate or lanceolate-ensiform, more attenuate towards the base than at 
upper end, where they terminate in a triangular acute and at the sides bristly- 
spinulous tip, green and quite free from bristles or spinules on both surfaces, 
longitudinally plicate, and finely striated with many slender secondary nerves ; the mid- 
costa alone is slightly raised, and not very strong ; the transverse veinlets are very minute, 
short, and numerous, are immersed in the parenchyme and render the upper surface 
minutely grained under a lens; the margins very minutely, remotely and appressedly 
spinulous; the intermediate leaflets are 25-35 cm. long, 3-4 cm. broad; the basilar 
usually narrower and longer, and those of the apex shorter and narrower, Male spadiz 
before flowering nodding, rather elongate, cylindraceous and slightly clavate (40 cm. long 
and 25 cm, thick in one specimen), with a short, slender, flattened, acutely two-edged, 
unarmed, peduncular part which gradully broadens into the outer spathe; the latter 
clavate, or almost ear-shaped but split along the ventral side, 2-keeled only at its base, 
and, like the inner spathes, very thickly coriaceous, and entirelyc overed externally 
; narrowly
