D. angustifolius.] BECCARI. THE SPECIES OF DAEMONOROPS. 69 
OssrRvaTIONs.—l have received some specimens of this, with female spadices in 
flower, from the Botanic Garden of Buitenzorg, where it is cultivated under the 
original name of D. marginatus T. et B. Under the same name I have received 
some loose fruits from the Utrecht Herbarium, and these have enabled me to recognise 
as belonging to this species a fine, entire spadix loaded with fruits, which I have 
also received from Buitenzorg; the characters of the fruiting spadix in the 
description above are derived from this material. 
D. Binnendykit, though in general appearance and dimensions similar to D. 
trichrous, offers some characters of its own which render its identification no very 
difficult task. The involucrophorum is not distinctly callous at its axilla and the 
involucre of the female flower conspicuously protrudes beyond the involucrophorum, 
has a thick base, and one of its sides is wholly occupied by the flat and not 
swollen areola. of the neuter flower. Further D.  Binneadijkü.. differs. from. D.. 
trichrous and D. angustifolius in its outer spathe, which is armed with long, broad, very 
thin, laminar, often laciniate and excessively finely acuminate spines, and in the 
beak armed at its base with very long spreading spines.

DESCRIPTION. —Scandent, of moderate size. Sheathed stem 2-25 cm. in diameter, ' 
Leaf-sheaths armed with many flat, solitary, scattered or sub-seriate narrowly triangular, 
rather short, unequal spines, of which the largest are about 1 cm. long; petiole short 
(10 em. long in one specimen), flattish on its upper surface, where densely armed, 
especially near the margins, with very short, straight, flat, triangular, ascendent spines, 
on the lower surface convex but similarly armed as on the upper with short spines even 
on the margins; rachis in its lower portion prickly on both surfaces like the 
petiole, higher up minutely spinulous on the salient angle; the latter at first obtuse 
and very acute and smooth from the middle upwards, furnished beneath with 
3—5-nate claws, which become  half-whorled on the terminal cirrus. Leaflets 
numerous, very regularly and closely set, 10-15 mm. apart, more spreading 
than in allied species, often almost horizontal, linear, comparatively very narrow, 
thinly papyraceous, green on both surfaces, 20-25 em. long, 8-10 mm. broad, some- 
what narrowed to a not very acute base, gradually acuminate from above the 
middle to a capillary tip, rather distinctly tricostulate on the upper surface where 
the mid-costa is bristly spinulous only from the middle upwards, and the side costulae _ 
are furnished from not very far above the base with rather long bristles; on the 
lower surface the mid-costa only is closely spinulous-ciliate. Male and female
