species, by the long spines at the base of the petiole and by its flattened male 
spikelets with closely packed bifarious flowers; but Ø. geniculatus has only partial 
membranous crests around the ieaf-sheaths, not complete reversed collars,

No. 1993 in Herb. Beccari. 
74. DAEMONOROPS MACROPHYLLUS Becc. in Hook f. b], Brit. Ind. vi, 470, and 
in Rec. Bot. Surv. Ind. ii, 227. 
DescripTion.—Scandent, rather slender. Sheathed stem 16-18 mm. in diameter. 
Leaf-sheaths cylindraceous, elongate, densely bristly-spinulous at the mouth, greenish, 
apparently covered with a rusty cottony furfuraceous scurf while young, later glabrous 
and almost polished, rather thin, easily splitting longitudinally, each furnished with 
several complete, very approximate, spiculiferous collars, of which 3-4 are larger than 
the others, and have a broad, reversed membranous part; below each of these large 
reversed collars is opposed a rudimentary one, armed with spiculae pointing upwards 
which cross and interlace with those of the upper collar, thus forming 3-4 complete 
ant-harbouring galleries around each sheath; all the spiculae are extremely slender, 
filiform or bristle-like, brittle, blackish or often discoloured. Leaves cirriferous, with 
only five opposed pairs of very large leaflets, the pairs on each side separated by a 
long vacant space; petiole very long (60 cm. long, 7 m m. broad}, flattened-biconvex 
with bluntish edges, armed at the base with a few, long, straight, 
and higher up with small claws; the rachis on the upper surface 
smooth salient angle and flat side-faces which begin at the insertion 
leaflets; on the under surface the rachis is armed with 3-nate claws, which become 
smaller on the slender cirrus. Leaflets papyraceous, elliptical-lanceolate, aimost equally 
tapering to both ends, terminating in a triangular and at the sides bristly-spinulous 
tip: those of the lower pair are very large, 50 cm. long, 10-i2 em. broad, and 
have 7-8 slender but acute costae, which are all of about the same strength, 
and smooth on both surfaces; transverse veinlets numerous, approximate and 
very sharp on both surfaces; margins excessively minutely spinulous; the leaflets 
of the upper pair do not differ from those of the lower one, only they are 
smaller, 25 em. long, 45-5 cm. broad, and 3-costulate. Flowers ...... Fruit 
deflexed spines,

Father Scoriechini (Herb. Beccari). 
OBSERVATIONS. —Of this Scortechini preserved only an entire leaf with a portion 
of the sheathed stem, apparently detached from an adult, but not yet fertile 
plant. If the characteristics given above are specific and not transient or 
variable structures, D. macrophyllus is easily distinguishable by its completely paired 
and opposed criniferous collars, and by the very few large, paired, pluri-costulate
