140 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUITA. [D. elo ngatus 
surfaces, papyraceous, very narrowly lanceolate or lanceolate-ensiform, broadest 
not very far above the base, narrowing thence shortly towards it, and upward 
gradually acuminate to a finely subulate and, at the sides, bristly-spinulous tip; 
on the upper surface: the mid-costa is slender and sharp, spinulous only near the 
upper end, and accompanied on each side by a slender secondary nerve (stronger 
however than several other nerves of the same kind) furnished with several short 
blackish bristles; underneath, the mid-costa alone is more or less minutely bristly- 
spinulous; transverse veinlets very sharp on both surfaces, numerous and much 
interrupted; margins finely and closely spinulous; the largest leaflets are those a 
little above the base which are 25-28 cm. long, 18-20 mm. broad in Motley’s. 
Bornean specimens, and as much as 35-40 cm. long and 25 mm, broad in the 
cultivated plants; the leaflets towards the upper end are gradually shorter and more, 
spaced.  Spadices, male and female, very similar, before flowering very narrowly 
cylindrical and elongate, slightly arched and nodding; primary spathes coriaceous, at 
first tubular, each protruding considerably beyond that immediately below, obliquely 
truncate at the mouth; after the anthesis the outermost spathe spreads out and is 
narrowly elliptical or elliptical-lanceolate or at times subspathulate or spoon-shaped, 
gradually diminishing towards the base to a more or less elongate, sparsely prickly 
aud flattened pedicellar part; it also narrows slightly above to a shortly bidentate. 
apex, is reddish brown and polished inside and more or less rusty-furfuraceous 
externally, where it is entirely covered with small solitary, more rarely digitate, 
scattered, deflexed, brown spines, which rest on a lighter anl sub-bulbous base; 
inner spathes deciduous, broadly linear, briefly bi-deatate at the upper end, more or 
less striate longitudinally; the second rather densely, the others sparingly 
prickly towards the apex, the ultimate spathes unarmed. Mal spadiz 40-75 cm. 
long; the flowering panicle strict, very  slenderly  fastigiate and with 6-8 
partial inflorescences, more or less persistently rusty-furfuraceous in every part; 
its main axis is cylindraceous or obsoletely angular, as slender as a  pack-thread, 
usually marked by numerous small depressions; partial inflorescences about 10 em. 
long, cupressiform and appressed to the main axis, (the ultimate smaller), formed by 
10-12 branchlets, each bearing 8-10 gradually diminishing fastigiate spikelets; secon- 
dary and tertiary spathes small, very shortly embracing, produced at one side into a 
short bracteiform, triangular, acute point; spikelets small, filiform, the lower (largest), 
9-10 mm. long, and with 8-10 unilaterally set flowers; their axes irregularly 
sinuous, and strongly indented at the insertions of the flowers which are often in pairs: 
spathes very small, produced at one side into a triangular, not very acute point; 
involucre very small, with the limb reduced to a very narrow annular rim round the 
circular scar, Male flowers very small, oblong, 3-5 mm. long; the calyx very 
shallowly cupular, with 8 small acute teeth; the corolla jseveral times longer than 
the calyx. Female spadiz about as long as the male or rather shorter; the peduncular 
part sometimes 20 cm, long, usually less, flattened, more or less armed all round with 
deflexed, solitary orconfluent, and subdigitate, straight, rather short spines: it slightly 
broadens above, where it gradually passes into the first spathe; the flowering panicle. 
is oblong, formed by 6-7 partial inflorescences; the main axis is straight, has the 
lowest internodes short, terete, and about 5 mm. in diam. while the other internodes. 
are more or less angular; the secondary and tertiary spathes are very small, scarious,
